Backwardly inclined plate blade fans
High Flow Rates, Clean Air Application, Low to medium Pressure
55 series high flow rate standard designs to 5 kPa(Flat Plate Blade)
52 series medium flow rate pressures to 6 kPa (Flat Plate Blade)
RMA medium flow rate pressures to 5 kPa
The Backwardly inclined plate blade fan is designed to handle large volumes of relatively clean air, commonly used for industrial air supply and exhaust applications. Heavily Constructed with Hardened alloy steel plate. Has a Performance air flow of 344,300 CFM (584,965 m3/hour) & static pressure to 14 inches w.g. (3,480 Pa). Capable of coping with non-sticky abrasive dust loads & has an efficient strong shape. This design is a cost-effective alternative to the backward curved design but with flat plate blades instead of curved. This results in a slightly lower efficiency, compensated by the easier fitting of liners.
