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. ASHRAE 62.1 is the reference cited for it on drawings, datasheets and purchase orders.
What ASHRAE 62.1 Means for Hydrophobic Mesh Moisture-Eliminator Air Filter
The dimensions in the table below are supplied to suit ASHRAE 62.1. 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.
Hydrophobic Mesh Moisture-Eliminator Air Filter Dimensions
| Size | Width (mm) | Height (mm) | Thickness (mm) | Media | Max face velocity (m/s) |
|---|---|---|---|---|---|
| 24 u00d7 24 u00d7 2 in | 610 | 610 | 50 | Knitted SS304 + PP layers | 3.0 |
| 24 u00d7 12 u00d7 2 in | 610 | 305 | 50 | Knitted SS304 + PP layers | 3.0 |
| 24 u00d7 24 u00d7 4 in | 610 | 610 | 100 | Knitted SS316 multi-layer | 3.5 |
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.
