Product Features


Low Pressure Screw Air Compressor

 Discharge Pressure: 0.15-0.4 Mpa

 Discharge delivery: 1.91-85.00 m3/min

 Motor Power Range:7.5-355 KW

It will consume a terrible waste of electric power by choosing a routine 0.7Mpa air compressor when the required pressure is 0.2-0.5 Mpa. More air delivery will be generated by choosing relatively low pressure screw air compressor under the same motor power. Correspondingly, low pressure compressor can help you to save electric power by 20%-50%.

If you purchase 0.7 Mpa compressor, but your actual application pressure is 0.3 Mpa, its work process as follows: the screw airend firstly compresses air to be 0.7 Mpa, then reduces the pressure to be 0.3 Mpa through pressure reducing valve or other approaches. That is to say, you use 0.3 Mpa pressure, but endure 0.7 Mpa power consumption.

It can be also proved by air delivery as follow:

  One 132KW screw air compressor with 0.7 Mpa, its air delivery should be 24m3/min, however, the air delivery can reach 39.8m3/min@0.3Mpa by choosing low pressure compressor! The saved power fare can recoup your capital outlay within one year.

As per users’ working pressure, it can be automatically adjusted the compression ratio, and within the exhaust pressure range of 0.2-0.5 Mpa, the best specific power can be maintained (energy efficiency). Using oil pump force-lubrication, Make sure the adequate oil injection and best oil/gas mixing ratio under the very low exhaust pressure.
