AMCA 500-L Hydrophobic Mesh Moisture-Eliminator Air Filter Specifications

A rectangular knitted stainless steel mesh moisture eliminator filter panel installed in a rooftop air intake louver

Hydrophobic Mesh Moisture-Eliminator Air Filter is used for stripping rain and mist droplets out of outdoor air intakes so water does not soak downstream filters, coils and ductwork. AMCA 500-L is the reference cited for it on drawings, datasheets and purchase orders.

What AMCA 500-L Means for Hydrophobic Mesh Moisture-Eliminator Air Filter

The dimensions in the table below are supplied to suit AMCA 500-L. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Hydrophobic Mesh Moisture-Eliminator Air Filter Beyond the Standard

  • 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.

When Hydrophobic Mesh Moisture-Eliminator Air Filter Is Not the Right Choice

Not a particulate filter — fit standard filters downstream.
