Application

Fantech’s FADE Series axial fans are designed to effectively and quietly handle major ventilation challenges in locations such as large warehouses without taking up a lot of valuable space.

Design

All FADE Series fans combine aerodynamically designed propeller blades and an external rotor motor expertly integrated into one unit. Fans feature a heavy gauge galvanized steel and powdercoated finish casing. With fan sizes ranging from 8” to 25”, Fantech’s FADE Series fans move a lot of air, yet are statically and dynamically balanced for vibration-free operation. The external rotor motorized propeller provides excellent heat dissipation, even at low RPM. Rated for continuous duty.
