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.
Equipment /Specific Ratio /Pressure rise (mmWg)
Fans /Up to 1.11 /1136
Blowers /1.11 to 1.20 /1136 2066
Compressors /more than 1.20 /

Difference between fan blower and compressor?
The pressure rise which is the main difference between fans, compressors and blowers can be stated as follows: ΔP(psig) Fans 2 Blowers 2-10 Compressors >10
Why do you use capacitors on fan motors or blowers?
We use capacitor on fan motor or blower to create phase difference between two winding(Starting & running). This phase difference introduce starting torque on fan motor. Otherwise without capacitor the torque produced in positive Half cycle of AC supply is nullify by the torque produced in negative half cycle.
