Axial Roof Upblast

Axial roof mounted upblast exhaust fans are named so due to the axial type blade that are used, as opposed to the wheel type blades used on centrifugal type fans. The axial roof exhausters is typically used in areas where lower static pressures exist, and higher CFM's are needed. The RTA roof exhaust fans move even more air than the RB and RD series, with CFM's to 75,000.
