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. Motor bearings are a permanently sealed, self-lubricating ball type. The square design provides a larger discharge area than tubular centrifugal or vane axial fans, so outlet velocities are reduced for quieter operation.
Features:
- Lightweight square design provides a larger discharge area and quieter operation
- Mixed flow impeller design incorporates high flow with higher pressure, non-overloading characteristics and automatic reset thermal overload protection
- 100% speed controllable
- Airstream temperatures of up to 140° F
- UL Listed and AMCA Certified
- Three-year warranty
