The Draw-Through Filtered Exhaust Fan is well suited for Paint Spray Booth applications (for example).

Takes the hassle out of having to build your own filter box and filters. (Filter Box is “removable”)

The Blow-Through Filtered Supply Fan is for SUPPY-AIR (INTAKE) applications. It is recommended that our INLET WEATHER HOOD be use with Supply Air Fans, to keep weather and birds from being pulled into the fan unit.
