Backward Curved Fans 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 & dust. Backward curved fans are known as “non overloading” 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.
