2-Inch Depth Advantages

The 2-inch depth configuration of the HPG201624 represents a strategic advancement in permanent filter frame technology, delivering substantial operational and economic benefits compared to standard 1-inch depth frames through enhanced dust-holding capacity and dramatically extended service intervals that reduce maintenance labor costs while improving overall filtration performance.

Extended Service Intervals and Reduced Maintenance Frequency

The primary advantage of 2-inch depth media accommodation lies in the dramatic reduction of filter maintenance frequency enabled by the higher dust-holding capacity of thicker filter media. Standard 1-inch depth filter media in commercial HVAC applications typically requires replacement every 30-60 days as pressure drop increases beyond acceptable levels or media becomes visibly saturated with particulate accumulation. In contrast, 2-inch depth media with 2-3 times the dust-holding capacity extends typical service intervals to 90-180 days in equivalent operating conditions, reducing maintenance frequency by 50-75% and delivering proportional reductions in maintenance labor costs. For facilities managing hundreds of filter locations across multiple buildings or large commercial properties, this reduction in maintenance frequency translates to substantial labor savings as maintenance staff complete filter changes quarterly instead of monthly, freeing personnel for other critical facility maintenance activities. The extended service intervals also reduce operational disruptions as HVAC systems experience filter maintenance events three to four times annually instead of twelve times, minimizing the risk of service scheduling conflicts with building operations, tenant activities, or critical production processes.

Enhanced Dust-Holding Capacity and Improved System Performance

The 1.75-inch actual depth of the HPG201624 frame accommodates significantly thicker filter media pads that provide 2-3 times the dust-holding volume compared to 0.875-inch depth 1-inch frames. This enhanced capacity means 2-inch media maintains acceptable pressure drop levels over extended service periods even as particulate accumulation increases, whereas 1-inch media reaches unacceptable pressure drop levels much earlier in the service cycle. HVAC systems operating with 2-inch media experience more gradual pressure drop increase over time, maintaining consistent airflow characteristics and system performance throughout the extended service interval. The thicker media construction also provides more uniform dust distribution across the media depth, preventing premature surface loading that can restrict airflow and increase pressure drop disproportionately. Facilities benefit from more predictable system performance between filter changes, with less variation in supply air volume, temperature control consistency, and energy consumption as filter media progressively loads with particulates. The enhanced dust-holding capacity particularly benefits facilities in high-particulate environments such as manufacturing operations, distribution centers with frequent loading dock activity, or locations with elevated outdoor air contamination levels where 1-inch media would require impractically frequent replacement schedules.

Economic Advantages and Total Cost of Ownership

While 2-inch depth filter media typically costs 20-40% more than equivalent 1-inch media on a per-unit basis, the extended service intervals deliver net cost savings through reduced material consumption and dramatically lower maintenance labor costs. A facility replacing 1-inch media monthly incurs twelve media purchases and twelve maintenance cycles annually, whereas the same facility using 2-inch media on quarterly schedules purchases only four media pads and completes only four maintenance cycles per year. Even accounting for higher per-unit media costs, the facility realizes 40-60% reduction in annual material expenses and 65-75% reduction in maintenance labor costs, delivering total cost of ownership savings of 50-70% compared to 1-inch systems. The labor savings prove particularly significant in facilities with extensive filter inventories where maintenance staff productivity improvements enable reallocation of personnel to other facility maintenance priorities or allow facilities to defer additional maintenance staff hiring as building portfolios expand. The combination of permanent reusable holding frames with 2-inch depth media accommodation represents the most economical filtration solution for commercial and industrial facilities prioritizing both upfront cost reduction through media-only replacement and ongoing operational cost reduction through extended service intervals and minimized maintenance labor requirements.

Operational Benefits and Facility Management Advantages

Beyond direct cost savings, the 2-inch depth configuration delivers operational benefits that improve overall facility management effectiveness and reduce complexity in maintenance scheduling, inventory management, and vendor coordination. Quarterly filter maintenance schedules align naturally with other preventive maintenance activities typically performed on quarterly cycles, enabling facilities to consolidate maintenance activities and reduce the number of separate service events requiring scheduling coordination, building access arrangements, and potential disruption to occupants or operations. The reduced maintenance frequency simplifies inventory management as facilities maintain smaller safety stocks of replacement media while still ensuring adequate supply for scheduled maintenance activities, freeing up storage space and reducing working capital tied up in filter media inventory. Procurement activities consolidate into quarterly or semi-annual orders instead of monthly purchases, reducing administrative burden and potentially enabling volume pricing negotiations with suppliers. For facilities using contracted maintenance services, quarterly filter change schedules reduce annual service calls by 65-75%, proportionally reducing contract costs or enabling facilities to renegotiate service agreements at substantially lower annual rates. The combination of extended service intervals with permanent reusable frames transforms filter maintenance from a frequent operational burden requiring near-constant attention into a manageable quarterly activity that integrates seamlessly with other facility maintenance programs while delivering superior filtration performance and equipment protection.

Construction Features

The HPG201624 16x24x2 media pad holding frame represents precision industrial manufacturing with UL Classified 900 rating for continuous operation at 325°F. Every component is engineered for maximum durability and 5-10 years service in commercial HVAC applications, from the heavy-duty galvanized steel frame to the permanently attached face grid. The 2-inch depth configuration provides enhanced structural support for thicker filter media while maintaining the dimensional accuracy and build quality essential for reliable performance. 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.

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. 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. The deeper 1.75-inch frame profile required for 2-inch media accommodation maintains exceptional structural integrity while supporting the higher weight of thicker media pads without frame deflection or dimensional changes that could compromise seal integrity. 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-year service life. Professional-grade mitered corner construction with pop rivet fastening ensures the filter pad holding frame maintains perfect dimensional accuracy of 15.5″ 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.

Expanded Metal Face Grid

The permanently attached 30 gauge galvanized steel face grid represents a critical engineering component that secures thicker 2-inch 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 engineering specifically calibrated to support the higher weight and thickness of 2-inch media without deflection or displacement. The expanded metal manufacturing process creates a mesh pattern with uniform openings that distribute airflow evenly across the entire 364.25 square inch filter face area, preventing localized high-velocity zones that could damage delicate filter media or create uneven dust loading patterns. The 30 gauge steel thickness provides adequate structural support for 2-inch media weight 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. 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. 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.

Mitered Corner Assembly

Each corner of the HPG201624 frame features precision-mitered joints that create true 90-degree angles essential for proper sealing against standard 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 particular importance in 2-inch depth frames where deeper frame profiles require robust corner joints to maintain structural integrity. 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. Pop rivet fastening secures each mitered corner joint with permanent mechanical attachment that maintains frame integrity throughout 5-10 years of service, handling during filter media replacement, 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. Precision corner construction maintains the 15.5″ x 23.5″ face dimensions within ±1/16″ tolerance, providing reliable fitment in standard 16x24x2 nominal filter housings without gaps or interference issues that could complicate installation or reduce filtration effectiveness.

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 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. Maintenance personnel appreciate the time savings and reduced labor complexity of simply opening the hinged gate, removing contaminated filter media, inserting fresh 2-inch media, and closing the gate to secure the new media—all without removing the frame from its installed position. The wire gate construction adds minimal airflow resistance while providing adequate retention force to hold thicker 2-inch filter media securely against normal HVAC system airflow conditions, preventing media displacement or shifting that could create bypass gaps. 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 heavier 2-inch depth filter frames 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. 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-year service life without material degradation or structural compromise. Rapid drainage characteristics ensure frames return to dry condition quickly after cleaning operations, minimizing downtime and allowing prompt reinstallation with fresh 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. These practical maintenance features contribute to the extended 5-10 years service life typical of media pad holding frames, where proper care and occasional cleaning maintain the frame in like-new condition throughout years of filter media replacement cycles and continuous HVAC system operation.

Dimensional Accuracy and Quality Control

Manufacturing precision ensures each HPG201624 frame maintains exact dimensional specifications essential for proper fitment in standard filter housings and consistent performance across hundreds or thousands of frames deployed throughout commercial facilities. The actual dimensions of 15.5″ H x 23.5″ W x 1.75″ D provide appropriate clearance for installation in 16x24x2 nominal filter housings while maintaining close enough tolerances to prevent excessive bypass gaps that would compromise filtration effectiveness. 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. 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. 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 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.

Maintenance & Cleaning

The HPG201624 16x24x2 media pad holding frame requires minimal maintenance while delivering 5-10 years 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 on extended quarterly schedules that reduce filtration costs by 60-80% and maintenance labor by 65-75% while maintaining optimal HVAC system performance and indoor air quality standards.

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 filter media out of the frame, disposing of it according to facility waste management protocols. 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 1.75-inch frame depth accommodates standard 2-inch nominal thickness filter media pads without forcing or compression that could damage media structure. 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 media, insert fresh media ensuring proper edge coverage and flat positioning within the 1.75-inch depth cavity, and close the wire gate to secure the media in place. Verify the gate latches properly and that the new media appears properly seated without visible gaps or displacement that could compromise filtration performance.

Media Replacement Frequency Guidelines

Filter media replacement intervals for 2-inch depth media depend entirely on the specific filter media type installed, operating environment, particulate loading rates, and HVAC system design parameters, but typically extend 50-100% beyond equivalent 1-inch media schedules due to enhanced dust-holding capacity. Standard 2-inch depth fiberglass filter media pads in typical commercial HVAC applications generally require replacement every 90-120 days based on dust accumulation and pressure drop measurements across the filter assembly, compared to 30-60 days for equivalent 1-inch media. High-efficiency polyester media, enhanced pleated media inserts, or specialty filtration materials may support longer service intervals of 120-180 days or more depending on their specific performance characteristics and dust-holding capacities. 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 60-90 days to maintain acceptable pressure drop and system airflow, but still represent 50-100% improvement over 1-inch media schedules. 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 semi-annual replacement intervals or longer. 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. 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.

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. 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. 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. 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 filter media installed.

Long-Term Service Life Maintenance

Proper handling techniques and operational awareness extend the HPG201624 galvanized steel frame’s service life to 5-10 years while maximizing the cost savings and sustainability benefits of permanent holding frame systems with extended maintenance intervals. 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 filter housings. Store spare frames in protected locations away from heavy equipment traffic, potential impact hazards, or stacking loads that could distort frame geometry. Maintain records of frame installation locations, service history, media replacement schedules, and any observed damage or unusual conditions that could inform long-term asset management and capital planning for eventual frame replacement after years of service. Train facilities staff on proper frame handling, media replacement procedures, and inspection criteria to ensure consistent maintenance practices across shifts and personnel changes. Calculate total cost of ownership by comparing the one-time frame purchase cost plus recurring media-only replacement expenses on quarterly schedules against complete disposable filter assembly costs over 5-10 year planning horizons, demonstrating cost savings exceeding 60-80% for permanent holding frame systems with dramatically reduced maintenance labor. The combination of durable galvanized steel construction, 2-inch depth media accommodation enabling extended service intervals, simple media replacement procedures, 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 HPG201624 16x24x2 media pad holding frame follows straightforward procedures that fit standard 16x24x2 filter housings used throughout commercial and industrial HVAC systems. 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.

Pre-Installation Considerations

Before installing your new media pad holding frame, verify that your filter housing accepts standard 16x24x2 nominal size filters with actual dimensions accommodating 15.5″ H x 23.5″ W x 1.75″ D frames. The 2-inch depth represents a significant increase from 1-inch frames, so confirm your filter housing provides adequate depth clearance and that converting from 1-inch to 2-inch depth will not interfere with surrounding equipment, ductwork, or structural elements. 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. 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 16x24x2 size and that media thickness is compatible with the frame’s 1.75-inch depth 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 upgrading from 1-inch to 2-inch depth frames, verify that the deeper frame will fit properly within the available housing depth without interference. 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. The 3.7 pound frame weight remains manageable for one person while the rigid galvanized steel construction maintains shape during installation procedures without flexing or distortion. 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. 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. 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. Verify the frame fits snugly without excessive movement or gaps around the perimeter before closing the access door or reinstalling the access panel.

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. 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. The 2-inch depth media should show slightly higher initial pressure drop than equivalent 1-inch media due to greater media thickness, but this is normal and expected behavior. 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 typical of 2-inch depth media. Document the installation date, frame location, installed media type, initial pressure drop reading, and planned quarterly replacement schedule in your facility maintenance records to support long-term asset tracking and maintenance scheduling. 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 the extended service life benefits of 2-inch depth media.

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, particularly when extended service intervals through 2-inch depth media reduce maintenance frequency to quarterly schedules. Some facilities prefer replacing contaminated media on quarterly schedules rather than managing filter cleaning operations monthly, particularly in applications with heavy grease or contaminants that complicate washing. filter holding frames 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, and operational requirements specific to each application.

How often should I replace 2-inch media compared to 1-inch media?

In typical commercial HVAC applications, 2-inch depth media requires replacement every 90-120 days compared to 30-60 days for equivalent 1-inch media—a 50-100% extension of service intervals due to the enhanced dust-holding capacity of thicker media. Heavy particulate environments may require 60-90 day replacement cycles for 2-inch media compared to weekly or biweekly schedules for 1-inch media. Clean environments may extend 2-inch media to semi-annual replacement. The optimal approach involves monitoring pressure drop across the filter assembly and scheduling replacement when pressure drop exceeds manufacturer specifications, but most facilities implement quarterly replacement schedules for 2-inch media that dramatically reduce maintenance frequency compared to monthly 1-inch media schedules.

What is the airflow capacity of this filter pad holding frame?

The HPG201624 frame with 364.25 square inches of filter area supports approximately 758 CFM at 300 FPM face velocity or 1,265 CFM at 500 FPM face velocity.
