The wheel turn faster than propeller fans, enabling operation under high-pressures 250 – 400 mm WC. Choose the right fan 2. Backward-inclined fans are known as "non-overloading" because changes in static pressure do not overload the motor. Difference between Fans, Blowers and Compressors Fans, blowers and compressors are differentiated by the method used to move the air, and by the system pressure they must operate against. Fans have the specific ratio up to 1.11, blowers from 1.11 to 1.20 and compressors have more than 1.20. In multi-stage blowers, air is accelerated as it passes through each impeller. Since this has a direct effect on the speed of the fan, the frequency prevailing or being maintained in the plant also needs to be specified to the supplier.
