Face Velocity*
*Filter grilles: Tested without filters. Typical capacity is 2 CFM per square inch of nominal filter area. Recommended face velocity is 300-450 FPM. Velocities higher
will decrease filter performance, increase flow resistance, and possibly be of noise concern. Velocity measured 1" from face.
