Ideal for low pressure applications, especial for the textile, cement, glass industry and etc.

When applications of working pressure between 0.2 - 0.5Mpa, the selected conventional 0.7Mpa air compressor will cause a huge waste of electricity, the choice of low pressure screw air compressors in the same motor power can be a substantial increase in the compressed air production,energy saving could be up to 20-50% .

If you purchased the 0.7Mpa machine, while the actual use of working pressure is 0.3Mpa, its working process is usually like this: first air compressed to 0.7Mpa,then through the pressure reducing valve reducing its pressure to 0.3Mpa to use it . In other words, you are using 0.3Mpa pressure while withstand 0.7Mpa power consumption.

This also could be proved from the capacity:

A 132kW, 0.7Mpa screw air compressor, its capacity is 24m3/min. However choosing KHE132kW, 0.3Mpa screw compressor, the capacity more than 37m3/min,the electricity savings will allow you to recover the investment in less than a year.

According to user's use of pressure,these series automatically could adjust the compression ratio in the working pressure range of 0.2 ~ 0.5Mpa, and could maintain the best specific power (energy efficiency).

Pump forced lubrication--Make sure that there is sufficient fuel injection in low working pressure and the best oil and gas mixing ratio.
