Hydrophobic Mesh Moisture-Eliminator Air Filter is selected when an assembly or process calls for stripping rain and mist droplets out of outdoor air intakes so water does not soak downstream filters, coils and ductwork. This application guide to the AMCA 500-L / ASHRAE 62.1 type covers concrete end-uses, the specification checklist, correct installation, and where an alternative mesh or filter medium performs better.
Typical Applications for Hydrophobic Mesh Moisture-Eliminator Air Filter
Where Hydrophobic Mesh Moisture-Eliminator Air Filter is specified and bought:
- Rooftop units & AHUs: fresh-air intake moisture eliminators.
- Marine & offshore HVAC: salt-mist removal on ships and platforms.
- Generator & turbine rooms: air-intake protection.
- Data centers: outside-air economizer intakes.
How to Specify Hydrophobic Mesh Moisture-Eliminator Air Filter for Your Application
- Face velocity: Keep below about 3 m/s or droplets re-entrain.
- Media: Knitted SS304/316 layered with polypropylene for droplet capture.
- Drainage: Provide a drain path at the bottom of the frame.
- Standard: Quote AMCA 500-L / ASHRAE 62.1 and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Install upstream of particulate filters, with a drip tray below.
- Rinse off salt and dirt deposits periodically.
Common Selection Mistakes with Hydrophobic Mesh Moisture-Eliminator Air Filter
- Running above the rated face velocity, which carries water through.
- Leaving no drain path so water pools in the frame.
Where Hydrophobic Mesh Moisture-Eliminator Air Filter Is Not the Right Choice
Not a particulate filter — fit standard filters downstream.
