Fantech FSD Series Inline Square Duct Fans

The FSD Series is a mixed flow centrifugal type exhaust/supply fans for moderate size ventilation applications were specifically designed to provide the high flow of axial designs plus the higher pressure, non-overloading characteristics of backward curved impellers. The square design provides a larger discharge area than tubular centrifugal or vane axial fans, so outlet velocities are reduced for quieter operation.

  • Mixed flow impeller design incorporates high flow with higher pressure
  • 100% speed controllable
  • Airstream temperatures of up to 140° F
  • UL Listed and AMCA Certified
  • Three-year warranty

#1 Q:   What are the starting requirements for this motor? Motor starter ECT.
A:   Fantech does not list any inrush currents but they do recommend upsizing the controls. For example 10 amp controls for the 18 and 20 sizes even though their max amps is significantly lower.
