Once you’ve specified your custom dimensions and confirmed galvanized steel performance with extended cleaning intervals in your specific environment, future reorders through your online account maintain consistent filtration capability without the perpetual frustration of searching for compatible custom-sized industrial-grade replacement filters with adequate dust-holding capacity.

Material Selection Guide

The HIGS20 features industrial-grade galvanized steel construction with 7-ply media specifically engineered for applications requiring enhanced corrosion resistance, elevated temperature capability, and extended dust-holding capacity beyond aluminum’s limitations. Understanding when galvanized steel with 2″ depth provides optimal value—compared to cost-effective aluminum or premium stainless steel, and compared to thinner 1″ depth filters—ensures maximum service life, performance, cleaning interval extension, and return on investment based on your specific operating environment and maintenance requirements.

HIG: Galvanized Steel Construction (Industrial Grade – 2″ Depth)

The galvanized steel construction features 24-gauge hot-dip galvanized steel frame construction with 7-ply aluminum screen wire media and 30-gauge galvanized steel face grids, delivering enhanced corrosion resistance, elevated 325°F temperature capability, and 97 g/sq ft dust-holding capacity at moderate cost increase over aluminum. The protective zinc coating applied through hot-dip galvanizing process provides exceptional rust resistance in humid environments, moisture-rich atmospheres, and applications involving frequent washdown or cleaning protocols, while the 7-ply media configuration extends cleaning intervals by 42% compared to 5-ply 1″ filters. Choose galvanized steel with 2″ depth when your application involves moderately elevated temperatures (275-325°F), humid environments requiring enhanced rust resistance, industrial settings where aluminum might corrode prematurely OR where heavy particulate loading demands extended cleaning intervals to reduce maintenance labor costs, or when the 50°F higher temperature rating combined with superior dust-holding capacity provides necessary operational advantages over aluminum construction. Galvanized filters with 2″ depth excel in commercial laundries with heavy lint loading, printing facilities with continuous paper dust, food processing plants with grease and organic matter accumulation, humid industrial environments with sustained particulate challenge, manufacturing operations requiring extended maintenance intervals, commercial kitchens with elevated temperatures and heavy loading, and applications where aluminum’s environmental limitations OR inadequate dust-holding capacity compromise service life or create excessive maintenance frequency. The 5-10 year service life matches aluminum and stainless steel duration but delivers this longevity in significantly more demanding conditions while the enhanced dust-holding capacity maintains manageable cleaning intervals—making galvanized steel with 2″ depth the optimal value choice for harsh environments with heavy particulate loading where aluminum fails prematurely or requires excessive maintenance.

HIA: Aluminum Construction (Standard Grade – 2″ Depth)

Aluminum construction with .030″ thick aluminum alloy frames and 7-ply media provides cost-effective filtration solution for standard commercial and residential HVAC applications with normal indoor temperatures, dry environments, and moderate particulate loading. With 275°F continuous temperature rating and excellent corrosion resistance in non-humid conditions, aluminum with 97 g/sq ft capacity serves many HVAC environments at lowest initial cost. Consider upgrading to galvanized steel (HIGS20) when your application involves temperatures approaching or exceeding 275°F, sustained high humidity levels, frequent moisture exposure, heavy continuous particulate loading requiring extended cleaning intervals, or when premature aluminum corrosion has shortened filter service life in your specific environment. The moderate cost increase for galvanized construction delivers substantial service life extension in demanding conditions and extended cleaning intervals in high-particulate applications—providing better long-term value than repeatedly replacing corroded aluminum filters or performing excessive cleaning cycles on aluminum filters with adequate depth but insufficient environmental protection.

HIS: 304 Stainless Steel Construction (Premium Grade – 2″ Depth)

304 stainless steel construction with 24-gauge stainless steel frames, 7-ply stainless media, and all-stainless face grids provides maximum corrosion resistance and exceptional 900°F continuous temperature rating for the most extreme applications. Choose stainless steel over galvanized when your application involves extreme temperatures exceeding 325°F (foundries, commercial bakeries, industrial drying operations), highly corrosive chemical environments beyond galvanized steel’s capabilities, or when maximum service life in extraordinarily harsh conditions justifies premium initial investment. For most industrial applications with elevated temperatures (275-325°F), humid or corrosive conditions, and heavy particulate loading, galvanized steel (HIGS20) with 7-ply media provides optimal balance of enhanced durability, extended cleaning intervals, and cost-effectiveness—reserving stainless steel for truly extreme environments where galvanized steel’s 325°F rating or corrosion resistance proves inadequate. Note that service life for stainless steel is 5-10 years—the same as galvanized steel and aluminum—with stainless steel’s advantage being its ability to achieve this service life in extremely harsh environments rather than extended longevity in standard conditions. The 97 g/sq ft dust-holding capacity is identical across all three materials with 2″ depth.

1″ Depth vs. 2″ Depth Comparison

When deciding between HIGS10 (1″ nominal depth, 5-ply, 68 g/sq ft) and HIGS20 (2″ nominal depth, 7-ply, 97 g/sq ft), consider both space constraints and maintenance interval requirements. Choose 1″ depth (HIGS10) when filter housing depth is limited to 1″ nominal or when moderate dust loading allows acceptable cleaning frequency with 68 g/sq ft capacity. Choose 2″ depth (HIGS20) when filter housing accommodates 2″ nominal depth AND when heavy particulate loading, limited maintenance access, or labor cost considerations justify the extended cleaning intervals provided by 42% higher dust-holding capacity. In applications where both depths physically fit, the 2″ galvanized filter typically provides better long-term value in industrial environments with heavy dust loading by substantially reducing maintenance frequency—though initial cost is moderately higher. Both depths provide identical 325°F temperature rating, corrosion resistance, and 5-10 year service life with proper maintenance.

Construction Features

The HIGS20 Custom 2″ Galvanized Steel Washable Mesh Filter is engineered with precision manufacturing techniques, industrial-grade materials, and enhanced media construction that ensure every custom-sized unit meets rigorous quality standards for enhanced durability, corrosion resistance, and extended cleaning intervals. UL 900 Class 1 certification validates continuous operation capability at 325°F, while Made in USA construction guarantees dimensional accuracy and structural integrity throughout the filter’s 5-10 year service life in demanding industrial environments with heavy particulate loading.

Hot-Dip Galvanized Steel Frame Construction

The foundation of this custom filter begins with a precision-formed 24-gauge steel frame subjected to hot-dip galvanizing process, where the steel is immersed in molten zinc to create a metallurgically bonded protective coating. This galvanizing process provides superior corrosion resistance compared to aluminum’s natural oxide layer, preventing rust formation in humid environments, moisture-rich atmospheres, and applications involving frequent wet cleaning cycles. The 24-gauge thickness delivers excellent structural rigidity while the hot-dip zinc coating ensures the frame maintains dimensional stability and corrosion resistance throughout repeated thermal cycling between ambient and elevated operating temperatures up to 325°F. The 2″ nominal (1-3/4″ actual) depth provides increased frame depth compared to 1″ filters, accommodating the robust 7-ply media pack while maintaining proper airflow transition. Professional-grade mitered corners secured with galvanized pop rivets ensure the frame maintains perfect dimensional accuracy to your custom specifications throughout repeated cleaning cycles and years of service in demanding conditions with heavy particulate loading. Each custom frame is manufactured to your exact height and width requirements with ±1/8″ tolerance, ensuring precise fit without gaps or binding in your HVAC system’s filter tracks while the galvanized construction prevents the corrosion-induced dimensional changes that can compromise aluminum filter fit over time.

Enhanced 7-Ply Media Pack

The filtration media consists of seven layers of corrugated aluminum screen wire arranged in a precision criss-cross weave pattern specifically engineered for 2″ nominal depth applications. This 7-ply configuration achieves 43% dust arrestance efficiency while delivering 97 grams per square foot dust-holding capacity—42% more than 5-ply 1″ filters—substantially extending cleaning intervals and reducing maintenance frequency in high-particulate industrial environments. The aluminum media provides excellent particulate capture with lightweight construction while the galvanized steel frame and face grids deliver the enhanced structural durability and temperature capability required for industrial applications. Each layer features expanded mesh construction with carefully engineered strand spacing that captures large particulates through multiple interception stages. The seven-layer corrugated structure provides significantly increased surface area within the 2″ nominal depth while the criss-cross weave pattern ensures uniform particle distribution across the entire media pack. This engineering approach delivers effective pre-filtration performance with manageable pressure drop, protecting downstream HVAC components without overburdening system blowers—with galvanized steel construction ensuring the frame and face grids maintain structural integrity even when industrial operating conditions would compromise aluminum alternatives, and with enhanced dust-holding capacity ensuring cleaning intervals remain manageable despite heavy particulate loading.

Corner Drain System

Three strategically positioned corner drain holes facilitate rapid water evacuation following cleaning operations, with typical air-drying times of 30-90 minutes depending on ambient conditions. The open mesh construction and robust galvanized steel frame design enable complete water drainage without trapped moisture in corner joints or frame channels. This drainage system prevents water pooling that could lead to odor development while the hot-dip galvanized coating ensures the frame resists corrosion even with repeated wet-dry cycles throughout the filter’s multi-year service life. The galvanized steel construction naturally resists rust formation in humid environments and moisture-rich applications, maintaining structural integrity and filtration performance through thousands of operational hours and repeated cleaning cycles—delivering consistent dimensional accuracy and reliable filtration in conditions where aluminum frames would experience oxidation and potential warping. The enhanced 1-3/4″ actual depth accommodates the 7-ply media pack while the drain system ensures complete moisture removal regardless of filter depth.

Galvanized Steel Face Grid Protection

Both upstream and downstream faces incorporate 30-gauge galvanized steel protective grids that shield the 7-ply media layers from physical damage during handling, installation, and operation. These galvanized steel face grids distribute incoming airflow uniformly across the entire filter surface, preventing concentrated jet streams that could damage the media structure while maintaining the manageable pressure drop characteristic of 2″ nominal depth filtration with 7-ply media. The grid construction provides impact resistance against accidental contact during filter changeouts while the hot-dip galvanized coating ensures the face grids resist corrosion in humid or corrosive atmospheres where aluminum grids might oxidize. This protective layer ensures the custom-manufactured filter maintains its structural integrity and filtration performance throughout thousands of operational hours and repeated cleaning cycles in heavy-particulate environments, with galvanized steel construction delivering enhanced durability compared to aluminum in demanding industrial and commercial applications with elevated temperatures and continuous dust loading.

Maintenance & Cleaning Protocol

The HIGS20 Custom 2″ Galvanized Steel Washable Mesh Filter requires minimal maintenance while delivering 5-10 years of reliable service in demanding industrial and commercial environments. Unlike disposable filters that create ongoing frustration finding compatible replacements for custom sizes, this industrial-grade galvanized steel mesh filter with 7-ply media supports repeated cleaning cycles using simple water-based methods without expensive cleaning agents or replacement costs—with hot-dip galvanized construction ensuring corrosion resistance throughout years of wet cleaning cycles and with enhanced dust-holding capacity substantially extending cleaning intervals compared to thinner filters.

Cleaning Methods

Four effective cleaning methods accommodate different facility capabilities and contamination levels. Garden hose cleaning provides the simplest approach, using high-pressure nozzle settings to spray both sides of the 7-ply media until water runs clear—typically sufficient for most commercial and light industrial applications, though the 2″ depth requires thorough rinsing of both faces to ensure complete cleaning of the thicker media pack. Sink or tub soaking works well for moderate to heavy contamination, submerging the filter in warm soapy water for 15-30 minutes before rinsing thoroughly (galvanized steel benefits from mild detergent and tolerates more aggressive cleaning agents than aluminum without corrosion concerns, while the 7-ply media may require extended soak time compared to thinner filters). Commercial dishwashers offer hands-free cleaning for facilities with industrial dishwashing equipment, with galvanized construction tolerating standard commercial dishwasher temperatures and detergents without degradation—ensure dishwasher accommodates the 2″ depth dimension. Pressure washing delivers fast results for heavier contamination typical in industrial applications, using 1000-1500 PSI with warm water—galvanized steel’s robust construction tolerates higher pressure than aluminum while the protective zinc coating prevents rust formation even with repeated high-pressure wet cleaning, and the 7-ply media’s enhanced thickness requires thorough pressure washing from both sides to dislodge accumulated particulate from the deeper media pack. The hot-dip galvanized frame and face grids withstand repeated washing without corrosion or degradation, maintaining structural integrity throughout the filter’s service life while operating continuously at 325°F temperature rating.

Recommended Cleaning Frequency

Cleaning intervals depend on operating environment and particulate loading rates, with the HIGS20’s enhanced 97 g/sq ft dust-holding capacity extending intervals substantially compared to 68 g/sq ft 1″ filters. Light dust environments such as standard commercial applications require cleaning every 4-6 months—roughly 50% longer intervals than 1″ filters in equivalent conditions. Moderate industrial applications including manufacturing facilities and commercial operations benefit from cleaning schedules every 6-8 weeks—extended from monthly intervals typical with 1″ filters. High-particulate industrial environments with continuous heavy dust generation may need monthly to bi-monthly cleaning—extended from bi-weekly to monthly intervals required with thinner filters. Visual inspection provides the most reliable cleaning indicator—schedule cleaning when the 7-ply screen wire media appears visibly loaded with dust or when system airflow seems reduced. Monitor pressure drop across the filter if instrumentation is available, cleaning when resistance reaches 0.50″ w.g. to maintain energy-efficient system operation. In humid environments or applications involving frequent moisture exposure, inspect the galvanized steel frame periodically to verify the protective zinc coating maintains its integrity—though properly maintained galvanized filters typically show no corrosion throughout their 5-10 year service life. The enhanced dust-holding capacity of the 2″ depth substantially reduces maintenance labor costs compared to 1″ filters in equivalent high-particulate applications, making the HIGS20 particularly cost-effective in industrial environments where filter accessibility challenges make frequent cleaning expensive.

Handling Considerations for Galvanized Steel Construction

Galvanized steel filters with 2″ depth provide enhanced durability with moderate weight increase compared to aluminum construction and increased weight compared to 1″ depth, tolerating somewhat more aggressive handling and cleaning pressure while still benefiting from proper support during maintenance. Support larger custom sizes from underneath during cleaning and installation to prevent frame stress, particularly important with the increased weight of 2″ depth filters. The 24-gauge galvanized steel frame construction with 1-3/4″ actual depth provides excellent structural rigidity, though heavier custom sizes may require two-person handling for safe installation and removal—the combination of galvanized steel material and 2″ depth creates noticeably heavier filters than aluminum 1″ alternatives. The hot-dip galvanized coating tolerates repeated wet-dry cycles and mechanical cleaning without degradation—maintaining corrosion resistance and dimensional stability throughout years of service in demanding industrial and commercial applications. Avoid using extremely abrasive cleaning tools that might damage the protective zinc coating, though normal pressure washing, detergent cleaning, and standard handling poses no risk to properly galvanized construction. The enhanced media depth requires thorough cleaning from both sides to ensure complete particulate removal from the 7-ply structure.

Installation

Installing the HIGS20 Custom 2″ Galvanized Steel Washable Mesh Filter follows the same straightforward procedures as standard filters, with attention to proper orientation, secure seating, and depth clearance to ensure optimal performance from your custom-manufactured industrial-grade filtration solution with enhanced dust-holding capacity.

Pre-Installation Verification

Before installing your custom galvanized steel 2″ filter, verify the dimensions match your original specifications and that your HVAC system is completely shut down with power disconnected. Inspect the filter housing interior for accumulated dust, debris, or damage that could compromise the seal. The custom-manufactured filter should fit your housing precisely with minimal clearance—if excessive gaps exist, verify you’re installing in the correct location and orientation. Confirm the filter housing accommodates the 2″ nominal (1-3/4″ actual) depth—measure the housing depth to ensure adequate clearance for the thicker filter compared to 1″ alternatives you may have previously used. Check the condition of existing gaskets or sealing surfaces, replacing worn gaskets before installing your new permanent filter. Clean the filter housing interior thoroughly with a vacuum or damp cloth to ensure optimal sealing surfaces. Locate the airflow direction arrow marked on your new custom filter frame, ensuring you understand proper orientation before installation. Note the galvanized steel construction and 2″ depth for documentation in your maintenance records, particularly in industrial environments where tracking filter material specifications and media depth supports compliance and quality management protocols.

Installation Steps

With the HVAC system powered off and locked out, open the filter access door or remove the access panel. Carefully remove any existing filter, noting its orientation and airflow direction. Inspect your new HIGS20 custom galvanized steel 2″ filter and locate the airflow direction arrow clearly marked on the frame. The 2″ nominal (1-3/4″ actual) depth creates increased handling weight compared to 1″ filters, and the galvanized steel construction creates slightly heavier weight than aluminum—larger custom sizes will likely require two-person installation for safety. Insert the filter into the housing with the airflow arrow pointing in the correct direction of air movement through your system. Press the filter firmly into place, ensuring all edges seat properly against the gasket or housing walls without forcing—the 2″ depth requires verification that the filter seats completely within the housing depth. The robust 24-gauge galvanized steel frame construction prevents flexing during installation while the custom dimensions create proper fit without excessive gaps around the perimeter. Verify the increased depth doesn’t interfere with access doors, adjacent components, or housing closure. Secure the access door or panel, restore power, and restart system operation.

Post-Installation Verification

After system restart, listen carefully for any unusual sounds such as air whistling or rattling that might indicate improper seating or depth interference. Verify proper airflow by checking that air velocity at supply registers matches expected performance levels. The slightly higher pressure drop of the 2″ nominal filter with 7-ply media (0.10″ w.g. vs. 0.08″ w.g. for 1″ filters) means system performance should still maintain acceptable levels while providing substantially extended cleaning intervals. Document the installation date, custom dimensions, galvanized steel construction specification, and 2″ depth in your maintenance records for future reordering through your online account. The 43% dust arrestance efficiency with 97 g/sq ft dust-holding capacity begins immediately protecting downstream HVAC components from large particulates and debris while the extended capacity delays the first cleaning interval substantially compared to thinner filters. Establish a regular inspection schedule based on your specific environmental conditions to monitor dust accumulation and maintain optimal system performance throughout the filter’s 5-10 year service life. In humid or corrosive industrial environments, the galvanized steel construction provides peace of mind that the filter will maintain structural integrity and dimensional accuracy throughout years of demanding service where aluminum alternatives might experience premature degradation, while the enhanced dust-holding capacity ensures cleaning intervals remain manageable despite heavy particulate loading.

Frequently Asked Questions

Why choose 2″ galvanized steel over 1″ or aluminum?

Choose the HIGS20 (2″ galvanized steel) over alternatives when you need the combined benefits of industrial-grade corrosion resistance AND extended cleaning intervals from enhanced dust-holding capacity. The 2″ depth with 7-ply media provides 97 g/sq ft capacity—42% more than 1″ filters with 5-ply media (68 g/sq ft)—substantially extending cleaning intervals in high-particulate industrial environments. The galvanized steel construction adds 325°F temperature rating (50°F higher than aluminum) and superior rust resistance in humid conditions. Choose 2″ galvanized steel when your application involves elevated temperatures approaching or exceeding aluminum’s 275°F limit, humid environments where aluminum corrodes, AND heavy particulate loading where 1″ filter cleaning frequency becomes impractical. The combination delivers both environmental durability and extended maintenance intervals—providing better long-term value than repeatedly replacing corroded aluminum filters or performing excessive cleaning cycles on 1″ filters in heavy-dust applications.

How much longer can I go between cleanings with the 2″ filter versus 1″ filter?

The HIGS20’s 97 g/sq ft dust-holding capacity versus the HIGS10’s 68 g/sq ft represents 42% more capacity, typically translating to 40-50% longer cleaning intervals in equivalent particulate loading conditions. For example, if you currently clean 1″ filters monthly in your application, the 2″ filter would typically extend intervals to 6-8 weeks. In moderate-dust environments requiring quarterly cleaning with 1″ filters, the 2″ filter might extend to 5-6 months between cleanings. However, actual interval extension depends on your specific particulate characteristics, loading rate, and acceptable pressure drop—monitor your first cleaning cycle with the new 2″ filter to establish optimal interval for your application. The extended intervals reduce maintenance labor costs substantially in applications where filter accessibility challenges make frequent cleaning expensive.

Will the 2″ filter fit in my current 1″ filter housing?

No. The HIGS20 requires a filter housing designed for 2″ nominal (1-3/4″ actual) depth filters. If your current equipment uses 1″ nominal (7/8″ actual) depth filters, you cannot retrofit to 2″ depth without modifying the housing—the 2″ filter is nearly 1 inch deeper than 1″ filters. Before ordering the HIGS20, measure your filter housing depth to confirm it accommodates 2″ nominal filters. If your housing only accepts 1″ depth, order the HIGS10 (Custom 1″ Galvanized Steel) instead, which provides galvanized steel’s enhanced corrosion resistance and temperature capability in the thinner profile, though with lower dust-holding capacity (68 g/sq ft versus 97 g/sq ft).

Does galvanized steel affect filtration efficiency compared to aluminum?

No, material selection does not affect filtration performance. The HIGS20 galvanized steel filter provides identical 43% dust arrestance efficiency and 97 g/sq ft dust-holding capacity as aluminum (HIAS20) or stainless steel (HISS20) construction in 2″ depth. The 7-ply media configuration delivers the same particle capture performance and dust-holding capacity regardless of frame material. Material selection affects temperature rating (aluminum 275°F vs. galvanized 325°F vs. stainless 900°F), corrosion resistance, weight, and cost—but not filtration efficiency or dust-holding capacity. Choose galvanized steel for its enhanced environmental durability and temperature capability while achieving the same filtration performance as other materials, with identical cleaning interval benefits from the 2″ depth media pack.

Is galvanized steel washable and reusable like aluminum?

Yes, the HIGS20 galvanized steel filter is designed for repeated washing and reuse throughout its 5-10 year service life—identical to aluminum and stainless steel service life expectations. The hot-dip galvanized coating withstands repeated cleaning cycles using water-based methods, detergents, pressure washers, or commercial dishwashers without corrosion or degradation. In fact, galvanized steel’s superior rust resistance makes it more tolerant of aggressive cleaning protocols and repeated wet-dry cycles compared to aluminum—maintaining structural integrity and dimensional accuracy through years of regular washing in humid or moisture-rich applications where aluminum might experience oxidation. The 7-ply media requires thorough rinsing from both sides during cleaning to ensure complete particulate removal from the enhanced media depth.

Can I order aluminum, galvanized, or stainless in the same custom 2″ dimensions?

Yes, absolutely. Once you’ve specified your custom dimensions for the HIGS20 galvanized steel 2″ filter, you can order the same size in aluminum (HIAS20) for cost-effective applications or stainless steel (HISS20) for extreme conditions. Many facility managers maintain inventory in multiple materials for different zones—aluminum for standard areas, galvanized steel for humid or elevated temperature zones with heavy particulate, stainless steel for extreme applications. Your custom dimensions are saved in your account, making it easy to reorder in the same or different materials as needs change or as you optimize material selection based on actual operating experience. All three materials provide identical 97 g/sq ft dust-holding capacity and 43% filtration efficiency in 2″ depth.

How long does custom 2″ galvanized steel filter manufacturing take?

Custom galvanized steel 2″ filter manufacturing typically requires 5-10 business days from order confirmation to shipment, though production schedules may vary based on current order volume. Galvanized steel production may add 1-2 days to lead time compared to aluminum due to the hot-dip galvanizing process, but this modest lead time increase delivers substantial performance advantages in demanding applications. The 2″ depth does not significantly affect production time compared to 1″ or 4″ depths. Rush production is available for critical applications requiring faster turnaround. We recommend ordering before your existing filter reaches end-of-service to ensure continuous filtration coverage, particularly in industrial applications where extended lead times for custom-sized galvanized steel filters with enhanced depth might otherwise create operational challenges.

What maintenance does the 2″ galvanized steel filter require?

Galvanized steel 2″ filters require the same simple maintenance as aluminum construction—periodic washing with water-based methods when dust accumulation becomes visible or when pressure drop reaches 0.50″ w.g.—but with substantially extended intervals between cleanings due to the enhanced 97 g/sq ft capacity. The hot-dip galvanized coating requires no special maintenance or treatment, maintaining its corrosion protection throughout the filter’s 5-10 year service life with normal cleaning protocols. Clean using garden hose, sink soaking, commercial dishwasher, or pressure washer depending on facility capabilities and contamination level—ensure thorough rinsing of both faces of the 7-ply media. The galvanized construction tolerates aggressive cleaning methods without degradation—you can use stronger detergents and higher pressure than aluminum without corrosion concerns. The enhanced dust-holding capacity means you’ll perform fewer total cleaning cycles over the filter’s service life compared to 1″ alternatives, reducing cumulative maintenance labor substantially.

Why Choose the HIGS20 Custom 2″ Galvanized Steel Washable Mesh Filter?

Choosing the HIGS20 Custom 2″ Galvanized Steel Washable Mesh Filter eliminates the frustration and expense of searching for compatible replacement filters for HVAC systems with discontinued or non-standard dimensions while providing industrial-grade durability, enhanced corrosion resistance, elevated temperature capability, and substantially extended cleaning intervals that aluminum construction and thinner filters cannot match. Whether you’re maintaining commercial kitchen equipment operating at sustained elevated temperatures with heavy particulate loading, supporting manufacturing facilities with high humidity and continuous dust generation, servicing food processing plants requiring frequent washdown environments with limited maintenance access, or managing industrial systems where premature aluminum corrosion and excessive cleaning frequency have increased operational costs, this made-to-order galvanized steel solution with 7-ply media provides permanent filtration precisely matched to your unique dimensional requirements and demanding operating conditions. The custom manufacturing process ensures perfect dimensional fit while hot-dip galvanized steel construction with enhanced media depth ensures optimal performance, maximum service life in harsh environments, and manageable maintenance intervals despite heavy particulate challenge.

Built to the same rigorous quality standards as our stock HIG Series products, this custom filter features precision-engineered 7-ply media construction and UL 900 Class 1 certification with 325°F continuous temperature rating—50°F higher than aluminum’s limitation. The industry-standard 2″ nominal (1-3/4″ actual) depth profile fits the vast majority of HVAC filter tracks designed for 2-inch filters while the 97 grams per square foot dust-holding capacity extends cleaning intervals by 42% compared to 1″ filters, substantially reducing maintenance frequency and labor costs. Made in USA with premium 24-gauge hot-dip galvanized steel frames and 30-gauge galvanized steel face grids, each custom filter is manufactured to your exact specifications with ±1/8″ tolerance, ensuring precise fit and optimal performance throughout its 5-10 year service life in demanding industrial and commercial applications with heavy continuous particulate loading.

The permanent washable construction delivers exceptional long-term value compared to disposable alternatives—especially critical for custom sizes where finding compatible replacements creates ongoing frustration and expense and where galvanized steel’s enhanced durability extends service life significantly beyond aluminum in harsh operating conditions while the enhanced dust-holding capacity reduces maintenance frequency dramatically. Once you’ve placed your initial custom order, reordering identical galvanized steel 2″ filters is effortless through your online account, eliminating the need to re-measure or re-specify dimensions for future purchases. The 43% dust arrestance efficiency protects downstream HVAC components while the manageable pressure drop maintains acceptable system efficiency even with 7-ply media. Simple water-based cleaning when pressure drop reaches 0.50″ w.g. restores peak performance without expensive cleaning agents or professional services—but you’ll perform these cleanings far less frequently than with 1″ filters—with hot-dip galvanized construction supporting repeated cleaning cycles throughout the filter’s multi-year service life without corrosion or degradation.

Facility managers, property owners, HVAC contractors, and industrial maintenance professionals choose the HIGS20 when standard filters cannot solve their combined dimensional, environmental, and maintenance filtration challenges and when operating conditions demand materials and dust-holding capacity exceeding aluminum’s and thinner filters’ limitations.
