Key Benefits of Custom Aluminum Moisture Separator Washable Aluminum Mesh Filters
- Made to Your Dimensions: Fabricated to the exact height and width you specify—ideal for non-standard housing sizes, retrofit applications, and built-up filter banks where off-the-shelf catalog sizes do not fit. Provide your required dimensions when ordering and receive a precision-built filter with ±1/8” dimensional tolerance.
- 99%+ Efficient on 3-Micron Water Droplets: Independently tested and verified to capture over 99% of water droplets measuring 3 microns and larger, providing reliable moisture protection for chilled water coils, downstream HVAC components, fan motors, and ductwork systems where uncaptured moisture causes corrosion, biological growth, and equipment damage
- Dual Function — Moisture Separation and Particulate Filtration: Primary function as an impingement-type aluminum mist eliminator filter is complemented by secondary heavy-duty washable particulate filtration capability, making the HMAS10 a versatile single-filter solution for applications requiring both moisture control and airborne particle capture in one permanent filter unit
- Permanent washable mist eliminator filter design: Rinse with warm water to restore full aluminum mist elimination and moisture separation and filtration performance—no replacement media required. Eliminates the recurring cost and logistics of disposable filter programs while maintaining consistent moisture separation performance throughout decades of commercial and industrial HVAC service
- 275°F Maximum Operating Temperature: Rated for continuous operation at temperatures up to 275°F, making the HMAS10 suitable for demanding commercial and light industrial applications with elevated air temperatures where lower-rated filter alternatives would be damaged or degraded
- Heavy-Duty 9-Ply Aluminum Screen Wire Construction: Multiple layers of corrugated and flat aluminum screen wire provide the tortuous path geometry required for efficient impingement-type moisture separation, with sufficient structural integrity for frequent washing and long-term service in harsh environments including outdoor air intakes, industrial ventilation, and coolant mist applications
- Gravity Drainage System: 3/8” diameter drain holes along the bottom of the aluminum frame collect and divert captured moisture to a drain when the filter is installed upright with the TOP label facing upward. This passive drainage system requires no power, pumps, or active components
- Made in USA by AMFCO — UL Classified 900: Manufactured by American Metal Filter Company to exacting dimensional and construction standards ensuring consistent performance throughout years of demanding commercial and industrial service. Optional polyurethane gaskets available for side-access housing applications

Commercial & Industrial Applications
Carrier commercial HVAC equipment is deployed across a wide range of commercial, institutional, and industrial building types. The following applications represent the primary use cases for Custom Aluminum Moisture Separator permanent washable aluminum mesh filters.
The HMAS10 custom 1-Inch aluminum mist eliminator filter is specified for commercial, institutional, and industrial HVAC applications where standard catalog HMA filter sizes do not match the required housing dimensions. The make-to-order capability allows HVAC engineers, facilities managers, and building operators to specify precise filter dimensions for retrofit projects, non-standard ductwork, existing side-access housings with unusual dimensions, and built-up filter bank configurations requiring exact sizing for proper bypass prevention.
Non-Standard Housing Retrofit Applications
Existing commercial buildings often have HVAC systems installed with non-standard filter housing dimensions that do not match current catalog sizes. Outside air intake housings, side-access filter housings in older air handling units, and built-up filter banks assembled from site-specific ductwork frequently require custom filter dimensions that off-the-shelf products cannot satisfy. The HMAS10 custom aluminum mist eliminator provides the same HM Series impingement-type moisture separation performance in a filter built to the exact dimensions required for proper fitment in these non-standard housings, eliminating bypass gaps that reduce moisture capture efficiency and compromise downstream equipment protection.
Chilled Water Coil and Humidifier Protection
Data centers, server rooms, precision manufacturing facilities, healthcare environments, and other applications with strict humidity control requirements frequently have AHU configurations with non-standard filter section dimensions. The HMAS10 custom filter provides 99%+ moisture separation and water droplet separator efficiency in a 1-Inch impingement-type panel filter built to the exact AHU interior dimensions, capturing chilled water coil carry-over and humidifier droplets before they enter supply ductwork. Custom sizing ensures complete face coverage with no bypass gaps for critical moisture control applications where even small amounts of uncaptured moisture cause equipment damage, biological growth, or contamination.
Industrial and Coolant Mist Applications
Industrial ventilation systems handling coolant mist, metalworking aerosols, and process exhaust frequently use ductwork and housings fabricated to plant-specific dimensions that require custom filter sizing. The HMAS10’s 9-ply aluminum screen wire construction captures oil mist and coolant aerosol droplets through the same impingement mechanism used for water droplets, with the 275°F temperature rating and all-aluminum construction providing compatibility with common industrial coolant chemistry. Custom height and width allow precise fitment in industrial ductwork and exhaust housings without air bypass that would defeat mist capture performance.

Frequently Asked Questions
What dimensions can I specify for the HMAS10?
Height and width can be specified to your exact requirements in 1/8″ increments. The nominal depth is fixed at 1″ (7/8″ actual depth per HM Series convention). Contact Metal Air Filters with your required height and width to receive a quote and confirm lead time.
How does the HMAS10 aluminum mist eliminator filter work?
The HMAS10 operates on the impingement principle: water droplets and oil mist cannot follow the tortuous path through the 9-ply aluminum screen wire media layers at 500 fpm and collide with wire surfaces where surface tension holds captured liquid until it drains through the 3/8″ bottom drain holes. Achieves 99%+ efficiency on 3-micron+ water droplets.
How do I clean the HMAS10?
Rinse with a moderate-to-heavy stream of warm water from the clean side through to the dirty side until water runs clear. High-powered steam cleaning and chemical dips are not recommended. Air dry or shake off excess water before reinstalling. Filter Coat adhesive may optionally be reapplied after each wash.
What is the lead time for a custom HMAS10 order?
Lead time varies by dimensions and production schedule. Contact Metal Air Filters with your required dimensions and quantity to receive a current lead time quote. Custom orders cannot be returned or exchanged once production has begun.
What is the maximum operating temperature of the HMAS10?
The HMAS10 HMA aluminum model is rated for 275°F continuous operation. For higher temperatures, AMFCO offers HMG galvanized (325°F) and HMS stainless steel (900°F) variants.
Why must this filter be installed with the TOP label facing upward?
The 3/8″ drain holes are along the bottom of the frame and only function when the filter is upright with TOP facing up. Installing sideways or inverted prevents captured moisture from draining, reducing separation efficiency and potentially causing liquid re-entrainment into the airstream.
Are polyurethane gaskets available for this filter?
Yes—the HM Series may be supplied with polyurethane gaskets on the vertical sides of the frame for side-access housing applications. Specify the gasket option and indicate which sides require gaskets when placing your order.
How often should I wash the HMAS10?
Outside air intakes in dusty environments typically every 1–3 months; commercial moisture separation applications every 3–6 months; industrial coolant mist applications may need monthly washing. Inspect visually and monitor drain hole flow as washing indicators.
How does the HMA aluminum model compare to HMG and HMS models?
HMA (.030″ aluminum frame, 24 ga aluminum face grids): 275°F max, frequent and moderate washability. HMG (galvanized steel): 325°F max, frequent and rigorous washability. HMS (stainless steel): 900°F max. Contact Metal Air Filters for HMG or HMS custom sizing if higher temperature ratings are required.
