Fantech FSD Series Square Inline Duct Fans with Metal Housing
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.
