Backward Curved Blowers also known as Radial Fans are Centrifugal Fans with Backward Curved Blades. These Centrifugal Fans provide very good cooling at high pressure conditions. The impellers of these industrial fans are highly resistant to dirt and dust. Backward curved fans are known as non over loading because changes in static pressure do not overload the motor. Its hydraulic efficiency is very high. These External Rotor Motor Fans are ideal for cooling at high pressure conditions. Low cost speed control is possible by supply voltage variation, either by electronic method or by transformer.
Teral-aerotech Backward curved centrifugal fan (BCHS) is designed to handle high air volumes at high static pressures. Used to move mostly clean air, Backward curved centrifugal fan (BCHS) industrial fan can be used as a forced draft or induced draft fan for a wide range of industrial applications.
The backward-inclined blower wheel design consists of blades that slant away from the direction of wheel travel. Teral-aerotech backward curve fans are characterized by high efficiency, high and rugged long-life construction for high static pressure applications. Teral-aerotech fans are extremely efficient, requiring less horsepower than other types of fans. A variety of standard models or custom designs are available. Custom fans are available to whatever specifications needed.
