Series 41U

Series 41U Fiberglass Backward-Curved — Utility | Hartzell Air Movement
Fiberglass Backward Curved Utility Set

The Series 41U Backward-Curved Centrifugal Fan offers non-overloading horsepower characteristics, high efficiency, low noise and economy for most applications where corrosive elements exist in fume and vapor form. It is available only in single width, single inlet (SWSI).

The unit features a type FA, high-efficiency, solid fiberglass wheel built in one piece using a resin transfer molding. This process ensures repeatability and provides sealed, stronger joints. The tapered inlet side and airfoil design efficiently moves large volumes of air at high pressures. The wheel has a non-overloading horsepower characteristic curve.

Standard sizes are 12, 18 and 24". Fans are available in clockwise or counterclockwise rotation in all eight discharge positions, with rotatable housing.

Designed for quiet operation, the Series 41U is AMCA-certified for sound and air performance.
