Product Description

Product Description

 

If your equipment only needs compressed air below 0.5 bar, choosing a 2~5.5 bar low-pressure screw air compressor can save more than 30% of electricity compared to the common 8 bar screw air compressor. ROCKY's 2~5.5 bar low-pressure screw air compressor, which is specially tailored for the textile, cement, glass and other industries, has been fully recognized by the majority of users in terms of saving electricity.

 

Working principle of low-pressure screw compressor
1. Inhalation: Air enters the spiral groove of the rotor at the inlet end.
2. Compression: As the rotor rotates, the air inlet is closed, the lubricating oil injection volume decreases and the gas
pressure increases.
3. Exhaust: The compression process ends, the pressure is obtained, and the exhaust process begins.
