Booster compressor is used to boost the pressure in the system,by four to six times the normal pressure produced by machines in factories. Most of the factories are capable of boosting the pressure without needing a booster, but it is costly and requires a lot of work to power up the equipment . Hence a Booster Compressor makes it easier to produce and sustain higher than average pressures.
This compressor boost the 7-13 bar compressed air taken from rotary screw compressors upto 40 bars. Booster compressors can be pneumatic,electric, or diesel/nitrogen driven. Most of them are pneumatic as it is generally easy to use and only a relatively small amount of energy is needed.
