The natural air enters the stage compression through the air filter, mixes with a small amount of lubricating oil in the compression chamber, and compresses the mixed gas to the interstage pressure at the same time. The compressed gas enters the cooling channel and contacts with a large amount of oil mist, which greatly reduces the temperature. The cooled compressed gas enters the second stage rotor for secondary compression and is compressed to the final exhaust pressure. Then discharge the compressor through the exhaust flange to complete the whole compression process.
The high energy-saving two-stage compression screw air compressor adopts the design of two-stage air end, so that the specific power of the air compressor can achieve high efficiency.
