Low pressure screw air compressor
Model: MDL3-30A~MDL5-350A
Energy saving and environmental protection, eliminating waste
Many industries, such as chemical, glass, petroleum, textile, printing and dyeing, ceramics, etc., require compressed air working pressure of only 0.3-0.5Mpa. However, currently these industries generally use air compressors with pressure reducing valves installed at 0.7-1.0Mpa to achieve this, which is undoubtedly a huge waste of energy For this purpose, Saman has tailored low-pressure screw compressors for these industries, which can directly output the low-pressure air you need

Specially designed for the textile, cement, and glass industries - SAMAN 0.3Mpa low-pressure screw air compressor
When your air pressure is between 0.2-0.5Mpa, using a conventional 0.7Mpa air compressor will cause huge power waste. Choosing a low-pressure screw air compressor can significantly increase the compressed air production at the same motor power, and correspondingly, you can save 20-50% electricity.
If you purchase a 0.7Mpa machine and actually use a pressure of 0.3Mpa, its working process is usually as follows: the screw host first compresses the air to 0.7Mpa, and then reduces the pressure to 0.3Mpa through pressure reducing valves and other means for use. That is to say, you are using a pressure of 0.3Mpa and experiencing a power consumption of 0.7Mpa.
It can also be proven from the perspective of exhaust volume:
A 132kW, 0.7Mpa screw air compressor should have a displacement of 24m3/min. And choosing the Kaitain JN132kW, 0.3Mpa screw air compressor, its displacement exceeds 37m3/min! The saved electricity costs will allow you to recoup your investment in less than a year.
According to the user's usage pressure, the internal compression ratio is automatically adjusted to maintain optimal power efficiency within the exhaust pressure range of 0.2~0.5Mpa.
Using an oil pump for forced lubrication - ensuring sufficient fuel injection and optimal oil air mixture ratio even at lower exhaust pressures.
