Made in USA with stringent quality control ensures consistent dimensional accuracy and structural integrity that withstands years of filter media replacement cycles and continuous HVAC system operation with thicker, higher-capacity filter media installations.

Galvanized Steel Frame Construction

The foundation of this industrial media pad holding frame begins with a precision-formed 24 gauge galvanized steel perimeter frame engineered for maximum structural rigidity and dimensional stability throughout decades of continuous service supporting 2-inch depth filter media. This heavy-gauge construction provides superior resistance to warping, bending, and distortion even under continuous exposure to 325°F operating temperatures common in commercial HVAC systems and elevated ambient conditions in rooftop mechanical equipment—with enhanced structural integrity specifically calibrated to support the additional weight and airflow requirements of thicker 2-inch filter media without frame deflection or dimensional changes. The galvanized steel composition delivers exceptional corrosion resistance in humid environments, coastal installations, and conditions where moisture exposure could compromise frame integrity over years of operation. The zinc coating inherent to galvanized steel construction provides long-term protection against rust and oxidation, maintaining structural properties and appearance throughout the filter pad holding frame’s multi-decade service life. Professional-grade mitered corner construction with pop rivet fastening ensures the filter pad holding frame maintains perfect dimensional accuracy of 11.5″ H x 23.5″ W x 1.75″ D throughout its operational lifetime, preventing dimensional changes that could create bypass gaps allowing unfiltered air to circumvent the filter media. The rigid frame construction provides firm support for various 2-inch depth filter media types, maintaining consistent media positioning and preventing media sag or displacement under airflow pressure that could compromise filtration effectiveness—critical for thicker media that presents greater weight and airflow resistance compared to standard 1-inch alternatives.

Expanded Metal Face Grid

The permanently attached 30 gauge galvanized steel face grid represents a critical engineering component that secures 2-inch depth filter media firmly against airflow pressure while maintaining minimal airflow resistance and optimal system performance. This expanded metal construction—permanently attached to the inside flange on the air exit side of the frame—creates a rigid support structure that prevents filter media from being drawn through the frame under system airflow conditions, with structural characteristics specifically designed to support the greater weight and airflow resistance of 2-inch depth filter media. The expanded metal manufacturing process creates a mesh pattern with uniform openings that distribute airflow evenly across the entire filter face area, preventing localized high-velocity zones that could damage delicate filter media or create uneven dust loading patterns—particularly important for thicker 2-inch media where airflow distribution affects media utilization and service life. The 30 gauge steel thickness provides adequate structural support while maintaining an open area percentage that adds negligible airflow resistance to the overall filter assembly, ensuring HVAC system fans operate within design parameters and energy consumption remains optimized even with thicker 2-inch depth filter media installed. The permanent attachment method—typically spot welding or mechanical fastening—ensures the face grid never separates from the frame during filter media replacement operations, handling, or years of continuous operation under varying airflow conditions and temperature exposures with heavier 2-inch media. The galvanized steel construction of the face grid matches the corrosion resistance properties of the main frame, providing consistent performance in humid environments or applications where periodic frame cleaning may be necessary to remove accumulated surface contamination from supporting thicker filter media over extended service intervals.

Mitered Corner Assembly

Each corner of the HPG201224 frame features precision-mitered joints that create true 90-degree angles essential for proper sealing against standard 2-inch depth filter housings and elimination of bypass air gaps. The mitered corner construction—where frame members are cut at precise 45-degree angles and joined at corners—provides superior strength and dimensional accuracy compared to simple butt-joint designs used in economy filter frames, with enhanced structural integrity to support the additional weight and airflow requirements of 2-inch depth filter media. This professional manufacturing approach distributes mechanical stresses evenly across corner joints, preventing localized stress concentrations that could lead to joint failure during handling or years of thermal cycling in HVAC applications supporting heavier filter media. Pop rivet fastening secures each mitered corner joint with permanent mechanical attachment that maintains frame integrity throughout decades of service, handling during filter media replacement with thicker 2-inch media, and exposure to vibration from HVAC equipment operation. The corner assembly design prevents frame racking or distortion that could compromise the critical dimensional accuracy required for proper fitment in filter housings, ensuring consistent performance and prevention of bypass airflow throughout the frame’s service life even when supporting substantially heavier 2-inch depth filter media compared to standard 1-inch alternatives. Precision corner construction maintains the 11.5″ x 23.5″ face dimensions within ±1/16″ tolerance, providing reliable fitment in standard 12x24x2 nominal filter housings without gaps or interference issues that could complicate installation or reduce filtration effectiveness with deeper media profiles.

Optional Hinged Wire Gate

The optional hinged wire gate—available as a specified feature at time of order—installs on the air entrance side of the filter pad holding frame to provide convenient 2-inch depth filter media retention without requiring frame removal from the filter housing during media replacement operations. This wire gate construction consists of a rigid wire frame assembly attached to the main filter frame via hinges, allowing the gate to swing open for media insertion and close securely to hold thicker 2-inch media in place during operation. The hinged design dramatically simplifies filter media replacement in applications where filter housings are installed in tight spaces, stacked filter banks, or locations where frame removal would require extensive disassembly of surrounding equipment or ductwork—particularly valuable when handling bulkier 2-inch depth filter media that can be more awkward to manipulate during installation. Maintenance personnel appreciate the time savings and reduced labor complexity of simply opening the hinged gate, removing contaminated 2-inch depth filter media, inserting fresh media, and closing the gate to secure the new media—all without removing the frame from its installed position or struggling with the handling challenges of thicker media in confined spaces. The wire gate construction adds minimal airflow resistance while providing adequate retention force to hold 2-inch depth filter media securely against normal HVAC system airflow conditions, preventing media displacement or shifting that could create bypass gaps—with structural design specifically calibrated for the greater weight and thickness of 2-inch media. Facilities managing large numbers of filter locations report significant labor cost reductions when using holding frames equipped with hinged wire gates, as media replacement operations complete faster with reduced complexity and eliminate the handling concerns associated with removing and reinstalling heavy filter frames supporting 2-inch depth media in mechanical rooms or rooftop equipment.

Drainage and Cleaning Features

Strategic corner drain holes integrated into the frame design facilitate complete moisture removal when periodic frame cleaning is necessary to maintain optimal airflow characteristics and remove accumulated surface contamination from years of service supporting 2-inch depth filter media. These drainage features enable maintenance teams to wash the galvanized steel frame using standard cleaning methods—pressure washing, spray washing, or manual cleaning with detergent solutions—without water becoming trapped in frame channels or corner assemblies where standing moisture could promote corrosion or support biological growth. The galvanized steel construction resists corrosion from water exposure and cleaning chemicals, allowing frames to be cleaned periodically throughout their multi-decade service life without material degradation or structural compromise even after years of supporting heavier 2-inch depth filter media. Rapid drainage characteristics ensure frames return to dry condition quickly after cleaning operations, minimizing downtime and allowing prompt reinstallation with fresh 2-inch depth filter media to restore HVAC system operation. The open frame design—with face grid providing the only obstruction to airflow—prevents dust accumulation in hidden pockets or complex frame geometries that would require extensive disassembly for thorough cleaning, maintaining accessibility even with the deeper 1.75-inch frame profile. These practical maintenance features contribute to the extended service life typical of media pad holding frames, where proper care and occasional cleaning maintain the frame in like-new condition throughout decades of filter media replacement cycles and continuous HVAC system operation supporting various 2-inch depth filter media types.

Dimensional Accuracy and Quality Control

Manufacturing precision ensures each HPG201224 frame maintains exact dimensional specifications essential for proper fitment in standard 2-inch depth filter housings and consistent performance across hundreds or thousands of frames deployed throughout commercial facilities. The actual dimensions of 11.5″ H x 23.5″ W x 1.75″ D provide appropriate clearance for installation in 12x24x2 nominal filter housings while maintaining close enough tolerances to prevent excessive bypass gaps that would compromise filtration effectiveness with 2-inch depth media installations. Quality control procedures verify dimensional accuracy within ±1/16″ on all critical measurements, ensuring frames install properly without interference or excessive looseness that could allow unfiltered air to bypass the filter media, with particular attention to the critical 1.75-inch depth dimension that must precisely match 2-inch nominal filter housing specifications. Frame squareness—the precision of corner angles and parallel relationship of opposite frame members—is verified to prevent racking or distortion that could create uneven gaps in filter housings or complicate installation of thicker 2-inch depth filter media. The consistent dimensional accuracy across production runs enables facilities to order replacement frames years after initial installation with confidence that new frames will match existing 2-inch depth filter housings without modification or fitment concerns. Made in USA manufacturing provides supply chain reliability and consistent quality compared to imported alternatives that may exhibit dimensional variations complicating filter system maintenance and reducing long-term cost predictability for facilities managing large filter inventories across multiple properties or locations requiring 2-inch depth filtration capacity.

Maintenance & Cleaning

The HPG201224 12x24x2 media pad holding frame requires minimal maintenance while delivering decades of reliable service through simple filter media replacement procedures. Unlike complete disposable filter assemblies requiring full unit replacement every 1-3 months, this industrial-grade galvanized steel frame supports economical media-only replacement strategies that reduce filtration costs by 60-80% while maintaining optimal HVAC system performance and indoor air quality standards. The 2-inch depth capacity accommodates high-capacity filter media that typically extends replacement intervals by 50-100% compared to standard 1-inch media, further reducing operational costs and maintenance labor requirements.

Filter Media Replacement Procedures

Filter media replacement represents the primary maintenance activity for media pad holding frames, with procedures varying slightly based on whether the frame includes optional hinged wire gate features. For frames without wire gates, remove the frame from its filter housing by sliding it out of the filter tracks or releasing frame retention hardware according to your specific HVAC system design. Position the frame on a clean work surface with the face grid side down, and carefully pull the contaminated 2-inch depth filter media out of the frame, disposing of it according to facility waste management protocols. The thicker media profile requires slightly more care during removal to prevent tearing or fragmentation that could leave media residue in the frame. Insert fresh 2-inch depth filter media into the frame, ensuring the media extends fully to all four edges without gaps that could allow bypass airflow, and verify the media sits flat against the face grid without wrinkles or folds that could restrict airflow—the thicker 2-inch media may require gentle compression or positioning to ensure proper fitment within the 1.75-inch frame depth. Reinstall the frame in the filter housing with proper orientation—typically with the face grid on the downstream (air exit) side—and secure according to system design using latches, pressure clips, or frame rails. For frames equipped with optional hinged wire gates, the replacement process simplifies significantly as the frame remains installed in its housing throughout the media change operation. Simply open the hinged wire gate by releasing its closure mechanism, remove the contaminated 2-inch depth media, insert fresh media ensuring proper edge coverage and flat positioning, and close the wire gate to secure the thicker media in place. The hinged gate design is particularly valuable when working with bulkier 2-inch depth media in confined mechanical rooms or tight filter bank installations. Verify the gate latches properly and that the new 2-inch media appears properly seated without visible gaps or displacement that could compromise filtration performance.

Media Replacement Frequency Guidelines

Filter media replacement intervals depend entirely on the specific filter media type installed, operating environment, particulate loading rates, and HVAC system design parameters, making general scheduling guidelines difficult to establish without application-specific information. The 2-inch depth capacity provides substantially greater dust-holding volume compared to standard 1-inch media, typically extending service intervals by 50-100% depending on media type and application conditions. Standard thick fiberglass filter media pads in typical commercial HVAC applications generally require replacement every 60-90 days based on dust accumulation and pressure drop measurements across the filter assembly—approximately double the service life of comparable 1-inch media in similar applications. High-efficiency 2-inch depth polyester media, pleated media inserts, or specialty filtration materials may support longer service intervals of 90-120 days or more depending on their specific performance characteristics and enhanced dust-holding capacities enabled by the deeper media profile. Heavy particulate environments including manufacturing facilities, warehouses with frequent loading dock activity, or locations with high outdoor air introduction rates may necessitate more frequent media replacement every 4-6 weeks to maintain acceptable pressure drop and system airflow—still representing substantial improvement over 2-4 week intervals typical with 1-inch media in similar conditions. Conversely, clean indoor environments such as office buildings with minimal outdoor air intake or facilities with upstream pre-filtration stages may extend 2-inch media service life to quarterly or semi-annual replacement intervals depending on actual contamination rates. The most reliable indicator for media replacement timing involves monitoring pressure drop across the filter assembly using differential pressure gauges or building automation system sensors, scheduling media replacement when pressure drop exceeds manufacturer specifications or reaches levels that compromise HVAC system performance—the greater dust-holding capacity of 2-inch depth media typically allows higher terminal pressure drop before replacement becomes necessary. Visual inspection provides supplementary guidance, with media replacement indicated when filter pads appear visibly loaded with dust accumulation, show media degradation or damage, or exhibit discoloration suggesting contamination or excessive service time—though 2-inch depth media may show surface loading while retaining substantial unused depth capacity, making pressure drop measurement particularly important for optimizing replacement timing.

Frame Cleaning and Inspection

Periodic frame cleaning maintains optimal airflow characteristics and removes accumulated dust or debris from the galvanized steel construction, though frame cleaning typically occurs less frequently than media replacement cycles. Most applications require frame cleaning annually or semi-annually depending on dust loading conditions, with visual inspection during routine media replacement operations indicating when cleaning becomes necessary. The 2-inch depth frame profile may accumulate slightly more surface dust compared to shallower frames due to greater exposed surface area, though the galvanized steel construction facilitates easy cleaning. Remove the frame from its filter housing and position it in an area suitable for wet cleaning operations such as a mechanical room sink, outdoor washing station, or designated cleaning area with appropriate drainage. Use standard pressure washing equipment at moderate pressure settings (1000-1500 PSI), spray washing with garden hose, or manual cleaning with brushes and detergent solutions to remove accumulated dust, surface contamination, or residue from the galvanized steel frame and face grid surfaces. The deeper frame profile may require additional attention to ensure thorough cleaning of the interior surfaces that contact 2-inch depth filter media. Ensure thorough rinsing to remove all cleaning solution residue that could attract dust or interfere with filter media contact surfaces, and allow complete drainage through the corner drain holes before proceeding to drying. Air drying typically requires 30-60 minutes in normal ambient conditions, with the galvanized steel construction and open frame design facilitating rapid moisture evaporation even with the deeper 1.75-inch profile. Accelerated drying using portable fans, compressed air, or heat sources reduces waiting time to 15-30 minutes when rapid return to service is required. Inspect the cleaned and dried frame for any signs of damage including bent frame members, loose corner joints, separated face grid attachment points, or corrosion that could compromise structural integrity or filtration performance, addressing any identified issues before returning the frame to service with fresh 2-inch depth filter media installed.

Long-Term Service Life Maintenance

Proper handling techniques and operational awareness extend the HPG201224 galvanized steel frame’s service life to multiple decades while maximizing the cost savings and sustainability benefits of permanent holding frame systems. The 3.17-pound frame weight (heavier than standard 1-inch frames) requires mindful handling to avoid dropping frames or subjecting them to impact loads that could bend frame members, damage corner joints, or compromise dimensional accuracy essential for proper fitment in 2-inch depth filter housings. Store spare frames in protected locations away from heavy equipment traffic, potential impact hazards, or stacking loads that could distort frame geometry—the deeper 1.75-inch profile may be slightly more susceptible to crushing loads if improperly stored. Maintain records of frame installation locations, service history, and any observed damage or unusual conditions that could inform long-term asset management and capital planning for eventual frame replacement decades in the future. Train facilities staff on proper frame handling, 2-inch depth media replacement procedures, and inspection criteria to ensure consistent maintenance practices across shifts and personnel changes—emphasizing the handling differences between standard 1-inch and deeper 2-inch frames. Calculate total cost of ownership by comparing the one-time frame purchase cost plus recurring media-only replacement expenses against complete disposable filter assembly costs over 10-20 year planning horizons, demonstrating cost savings exceeding 60-80% for permanent holding frame systems—with the extended replacement intervals enabled by 2-inch depth media providing additional savings beyond the permanent frame economics. The combination of durable galvanized steel construction, simple media replacement procedures, extended service intervals from 2-inch depth media capacity, and minimal frame maintenance requirements makes media pad holding frames the most economical choice for commercial and industrial HVAC applications requiring reliable filtration with maximum service life and minimum total cost of ownership.

Installation

Installing the HPG201224 12x24x2 media pad holding frame follows straightforward procedures that fit standard 12x24x2 filter housings used throughout commercial and industrial HVAC systems requiring 2-inch depth filter capacity. Professional HVAC contractors or trained facility maintenance staff can complete the installation in minutes with proper procedures. Following the guidelines below ensures optimal performance, proper sealing, and long-term reliability of your galvanized steel holding frame system supporting 2-inch depth filter media.

Pre-Installation Considerations

Before installing your new media pad holding frame, verify that your filter housing accepts standard 12x24x2 nominal size filters with actual dimensions accommodating 11.5″ H x 23.5″ W x 1.75″ D frames. The 2-inch depth specification is critical—this filter pad holding frame will not fit properly in 1-inch nominal filter housings and requires filter slots or tracks designed for 2-inch depth filters. Inspect the filter housing interior for accumulated dust, debris, or damage that could compromise the seal or restrict airflow once the new frame is installed. Check the condition of existing gaskets or sealing surfaces in the filter housing, and have replacement gaskets available if current ones show signs of wear, cracking, or compression set that could allow bypass airflow—proper sealing is particularly important with 2-inch depth frames to prevent air from bypassing the greater filter media depth. Ensure the HVAC system is completely shut down and locked out before accessing the filter compartment for safety, following all facility lockout-tagout procedures and electrical safety protocols. Locate filter housing orientation indicators, airflow direction markings, or existing filter position to understand proper frame installation orientation for the new holding frame. Verify that your HVAC system operates within the frame’s temperature rating of 325°F continuous operation to prevent damage to the galvanized steel construction in extreme temperature applications. Select appropriate 2-inch depth filter media for your application requirements, ensuring media dimensions match the holding frame’s 12x24x2 size and that media thickness is compatible with the frame’s 1.75-inch depth capacity—verify the media is specifically rated for 2-inch applications to take full advantage of the enhanced dust-holding capacity. Clean hands or wearing clean work gloves during installation helps maintain frame cleanliness and prevents contamination of filter media that will be installed in the frame.

Frame Installation Steps

Begin by completely shutting down your HVAC system and verifying power disconnection to prevent accidental startup during installation work. Open the filter access door or remove the access panel according to your system’s specific design, noting any latches, fasteners, or retention mechanisms that must be addressed. Carefully remove any old filters from the housing, noting their orientation, airflow direction markings, and how they fit within the filter tracks or retention hardware—if replacing 1-inch filters with this 2-inch depth frame, verify the housing can accommodate the greater depth before proceeding. Thoroughly clean the filter housing interior using a vacuum cleaner or damp cloth to remove accumulated dust, debris, or residue that could interfere with proper frame seating or compromise sealing surfaces. If installing filter media in the frame before installation, position the frame on a clean work surface with the face grid side down, insert the 2-inch depth filter media ensuring complete edge coverage without gaps, and proceed with the loaded frame installation—note that the combined weight of frame plus 2-inch media will be greater than standard 1-inch assemblies. The 3.17 pound frame weight makes handling manageable while the rigid galvanized steel construction maintains shape during installation procedures without flexing or distortion even when supporting thicker 2-inch media. Insert the frame into the housing following the airflow direction appropriate for your application—typically with the face grid on the downstream (air exit) side to support media against airflow pressure—ensuring the frame tracks or guides designed for 2-inch depth filters properly engage with the frame edges. For frames with optional hinged wire gates, verify the gate can open freely for future media replacement without interference from surrounding equipment, ductwork, or structural elements, and confirm the gate mechanism operates smoothly with the thicker media profile. Press the frame firmly into place ensuring all edges seat properly against gaskets or housing walls to prevent bypass air leakage around the frame perimeter, and secure the frame according to your specific filter housing design using latches, retention clips, pressure bars, or filter tracks—the slightly heavier frame may require firmer pressure to fully seat compared to standard 1-inch alternatives. Verify the frame fits snugly without excessive movement or gaps around the perimeter before closing the access door or reinstalling the access panel, paying particular attention to proper depth engagement in the housing tracks.

Post-Installation Verification

After securing the filter access door or panel, restore power to the HVAC system and restart normal operation according to facility procedures and system start-up protocols. Listen carefully for any unusual sounds such as air whistling around the frame perimeter, rattling from loose frame installation, or abnormal fan noise that might indicate airflow restrictions or improper installation—the 2-inch depth media will present slightly higher airflow resistance than 1-inch alternatives, which is normal and should be within system design parameters. Verify proper system airflow by checking air velocity at supply registers or grilles matches expected performance levels, or by observing pressure readings if your system includes monitoring instrumentation. If your system includes differential pressure monitoring across filters, record the initial clean filter pressure drop reading to establish a baseline for future media replacement scheduling and system performance trending—expect slightly higher initial pressure drop with 2-inch media compared to 1-inch alternatives, but with substantially greater dust-holding capacity justifying the marginal resistance increase. Monitor the system operation for the first several hours after installation to ensure stable performance with no unexpected issues, pressure fluctuations, or temperature anomalies that could indicate installation problems. The holding frame’s rigid galvanized steel construction will immediately provide stable filter media support, maintaining consistent filtration performance and HVAC system protection throughout the extended media service life enabled by 2-inch depth capacity. Document the installation date, frame location, installed media type, initial pressure drop reading, and expected replacement interval in your facility maintenance records to support long-term asset tracking and maintenance scheduling—the extended intervals typical with 2-inch depth media make accurate record-keeping particularly valuable. Establish a regular inspection schedule based on your specific operating conditions to monitor filter media condition, measure pressure drop trends, and plan optimal media replacement timing that maintains system performance while maximizing media service life and minimizing filtration costs through the enhanced dust-holding capacity of 2-inch depth filter media.

Frequently Asked Questions

What types of filter media can I use with this 2-inch holding frame?

The HPG201224 media pad holding frame accommodates various 2-inch depth filter media types including thick fiberglass filter pads, high-capacity polyester media, extended-surface activated carbon sheets, antimicrobial-treated media, and specialty filtration materials with 2-inch thickness. The rigid face grid securely holds thicker media in place while allowing flexibility to select the most appropriate media type for your specific application requirements, whether basic dust control with extended service intervals, enhanced odor removal, or improved particle capture. Ensure selected media dimensions match the 12×24 frame size and that media thickness is appropriate for the frame’s 1.75-inch depth capacity—2-inch nominal media typically compresses slightly to fit within this dimension.

How is this different from a 1-inch holding frame?

This 2-inch depth holding frame (actual 1.75″ depth) accommodates substantially thicker filter media compared to standard 1-inch frames (actual 0.875″ depth). The deeper profile provides 2-3 times greater dust-holding capacity, typically extending filter media replacement intervals by 50-100% compared to 1-inch alternatives in similar applications. While the initial frame cost is slightly higher and the frame weighs more (3.17 lbs vs 2.08 lbs for 1-inch version), the extended media service intervals typically provide superior total cost of ownership by reducing media replacement frequency and associated labor costs. The 2-inch frame is ideal for applications with heavy particulate loading, facilities seeking to minimize maintenance frequency, or installations where extending intervals between filter changes provides operational benefits.

Can I install 2-inch filter media before mounting the frame?

Yes, you can install 2-inch depth filter media in the frame before mounting it in the filter housing, which many maintenance personnel find convenient for workspace organization and installation efficiency. Position the frame with the face grid side down on a clean work surface, insert the 2-inch depth filter media ensuring it extends fully to all edges without gaps (the media may require gentle compression to fit within the 1.75-inch frame depth), then install the frame with media in place into your filter housing. Note that the combined weight will be greater than standard 1-inch assemblies. Alternatively, for frames equipped with optional hinged wire gates, you can install the empty frame first and then insert 2-inch media through the hinged gate opening, which is particularly convenient when filter housings are installed in tight spaces or difficult-to-access locations.

How long does the frame itself last?

With proper handling and normal maintenance procedures, the HPG201224 galvanized steel holding frame delivers 5-10 years of reliable service life. The durable 24 gauge galvanized steel construction resists corrosion, maintains dimensional stability, and withstands repeated filter media replacement cycles without structural degradation even when supporting heavier 2-inch depth filter media. Many commercial facilities report holding frames remaining in service for years with only periodic cleaning required to maintain optimal condition. This exceptional longevity provides the foundation for significant long-term cost savings compared to disposable filter systems, particularly when combined with the extended media replacement intervals enabled by 2-inch depth capacity.

Does this filter pad holding frame come with filter media included?

No, the HPG201224 media pad holding frame is sold as a standalone component without filter media included. This allows you to select the specific 2-inch depth filter media type most appropriate for your application requirements and to establish your own media replacement inventory based on your actual consumption rates. Filter media is available separately from HVAC suppliers, filtration distributors, or online retailers in various efficiency levels and material types to match your performance and budget requirements—ensure you specify 2-inch depth media compatible with this filter pad holding frame’s 1.75-inch actual depth capacity.

What does the UL Classified 900 rating mean?

UL Classified 900 indicates this holding frame has been tested and classified by Underwriters Laboratories for continuous operation at temperatures up to 325°F in commercial and light industrial HVAC applications. This classification provides assurance that the galvanized steel construction maintains structural integrity and does not present fire hazards in high-temperature environments such as rooftop HVAC units, mechanical rooms with elevated ambient temperatures, or installations near heat-generating equipment—even when supporting heavier 2-inch depth filter media. The rating is particularly important for commercial building code compliance and insurance requirements.

Can this frame be cleaned or washed?

Yes, the galvanized steel construction allows periodic cleaning to maintain optimal condition throughout the frame’s multi-decade service life. Remove accumulated dust or surface contamination using pressure washing, spray washing, or manual cleaning with mild detergent solutions. The corner drain holes facilitate complete moisture removal after washing, and the corrosion-resistant galvanized steel construction withstands repeated cleaning without degradation. The 2-inch depth profile may accumulate slightly more surface dust than shallower frames due to greater exposed surface area, but the open construction facilitates thorough cleaning. While frame cleaning is typically less frequent than filter media replacement—perhaps annually or semi-annually—periodic cleaning maintains airflow characteristics and extends service life.

What is the optional wire gate feature?

The optional hinged wire gate installs on the air entrance side of the holding frame, providing a convenient opening for 2-inch depth filter media insertion and removal without requiring frame removal from the filter housing. The hinged gate swings open for media access and closes securely to hold thicker media in place during operation. This feature significantly simplifies media replacement in applications where filter housings are installed in tight spaces, stacked filter banks, or locations where frame removal would be difficult or time-consuming—particularly valuable when handling bulkier 2-inch depth filter media that can be awkward to manipulate in confined spaces. Wire gate availability must be specified at time of order.

Is this frame compatible with existing filter housings?

The HPG201224 fits standard 12x24x2 nominal filter housings with actual opening dimensions accommodating 11.5″ H x 23.5″ W x 1.75″ D frames. This represents industry-standard sizing used throughout commercial HVAC equipment from major manufacturers for 2-inch depth filter applications. CRITICAL: This frame will NOT fit in 1-inch nominal filter housings—the 1.75-inch depth requires filter slots or tracks specifically designed for 2-inch filters. Measure your existing filter housing or current filters to verify 2-inch depth compatibility before ordering. The frame’s dimensional accuracy ensures proper fitment in standard 2-inch housings without modification, though custom filter housings or non-standard installations should be measured to confirm dimensional compatibility.

Why choose a media pad holding frame instead of washable filters?

Media pad holding frames suit applications where disposable media replacement is preferred over filter washing procedures. Some facilities prefer replacing contaminated media rather than managing filter cleaning operations, particularly in applications with heavy grease or contaminants that complicate washing. The 2-inch depth filter holding frames frames provide the additional advantage of extended replacement intervals compared to both 1-inch disposable alternatives and washable filters, reducing maintenance frequency. Media holding frames also allow flexibility to change filtration efficiency levels by selecting different media types, whereas washable filters have fixed efficiency characteristics. The choice between holding frames and washable filters depends on facility maintenance preferences, contamination types, desired replacement intervals, and operational requirements specific to each application.

How much longer does 2-inch media last compared to 1-inch?

In typical commercial HVAC applications, 2-inch depth filter media lasts approximately 50-100% longer than comparable 1-inch media due to the substantially greater dust-holding capacity—essentially 2-3 times the media volume. Actual service life improvement depends on media type, dust loading conditions, and application specifics. For example, if 1-inch fiberglass media requires monthly replacement, comparable 2-inch media might extend intervals to 2-3 months in similar conditions. Heavy particulate environments still require more frequent replacement than clean applications, but the improvement ratio typically remains consistent across different contamination levels. The extended intervals reduce both media procurement costs and maintenance labor requirements, often justifying the moderately higher initial frame cost within the first year of operation.
