Answer Posted / arindam dhara
Fans, blowers and compressors are differentiated by the method used to move the air, and by the system pressure they must operate against. As per American Society of Mechanical Engineers (ASME) the specific ratio - the ratio of the discharge pressure over the suction pressure - is used for defining the fans, blowers and compressors
Fans Specific Ratio Presser rise upto 1.11
Blowers Specific Ratio Presser rise Upto 1.11 to 1.20
Compressors Specific Ratio Presser rise Upto more then 1.20
