Air Blowers are air cooled blowers and can be used upto a pressure 0.7
kg/cm 2 .In case pressure is more than 0.7 kg/cm 2 , water cooled
blowers are preferred.

Gas Blowers are used for boosting and conveying the gas. Gas is sucked from the system and delivered to the desired destination against the system pressure.

Generally water cooled Blowers are used for higher pressures, i.e. when the working pressure(Differential Pressure across the blower) is more than 0.7 kg/cm 2 .

Vacuum Blowers are used to create negative pressure(Vacuum). Vacuum Blowers finds application in the areas such as Vacuum Moulding, .
