The FSD series may be used for supply, exhaust, or ducted air movement where relatively high air flow rates against moderate static pressure is desired. The square design provides a larger cross-sectional discharge area than tubular centrifugal or vane axial fans, so outlet velocities are reduced for quieter operation

The motorized impeller is both statically and dynamically balanced as one integral unit, for vibration-free, quiet performance. Motor bearings are a permanently sealed, self-lubricating ball type.

One phase (1~) models are equipped with thermal overload protection with automatic reset. These models can be speed-controlled via a stepless thyristor. Three-phase (3~) models require an external contactor.
