Hydrophobic Mesh Moisture-Eliminator Air Filter in 304 Stainless Steel (AISI 304 (1.4301)) is used for stripping rain and mist droplets out of outdoor air intakes so water does not soak downstream filters, coils and ductwork. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Hydrophobic Mesh Moisture-Eliminator Air Filter Is Used
- 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.
Ordering Hydrophobic Mesh Moisture-Eliminator Air Filter in 304 Stainless Steel
- 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.
Mistakes to Avoid 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.
