The design of the filter media is such that the filter will function with complete satisfaction with face velocities ranging from 1.5m/s to 2.7m/s. This offers a great deal of latitude in selecting sizes.
Filter medial used is a metal honeycomb .24mm thick,manufactured from aluminum. .50mm wide aluminum strip is formed into a system of double compound curves so that when folded back on itself it forms a non-nesting system of smooth-walled honeycombs.
This special media design splits the incoming air into approximately 3,000 separate airstreams per square foot of filter surface.
