SLQ Series Low Pressure screw compressor

SLQ series low-pressure screw air compressor was specially designed for the textile, cement and glass industries. If you just need to use 0.2-0.5Mpa exhaust pressure, choosing the conventional 0 7Mpa exhaust pressure of air compressor will cause a huge waste of electricity. But if you choosing the low pressure screw air compressor will significantly increase the production of compressed air Gas volume in the same motor power. Accordingly, it also can save 20-50% electric power. If you bought a 0.7Mpa screw air compressor, but your working actual use of pressure is 0.3Mpa then its working process is usually like as below: the screw compressor firstly compressed the air pressure into 0.7Mpa, then through the pressure reducing valve and other ways to reduce the pressure to 0.3Mpa. In other words, you got the 0.3Mpa exhaust pressure, but you bore 0.7Mpa electric power consumption.
 
We can prove it from the gas displacement:

  • One type of 132KW, 0.7Mpa screw air compressor,its gas displacement(F.A.D) should be 24m3 / min. But if you choosing our Unical SLQ series Low power screw air compressor,its  gas displacement(F.A.D) overed 37m3 / min.You can recovery of the machine investment through the saved power cost in less than one year.
  • It can according to the users' ture needing pressure automatically adjust the internal compression ratio. It maintains the best specific power (energy efficiency) when in the exhaust pressure range within 0.2~0.5Mpa.
  • Forced lubrication with the pump - to ensure that very low exhaust pressure also has enough fuel injection, the best mixture of oil and gas.
