![]() The secondary compression rotor and the secondary compression rotor are combined in a housing and driven directly by helical gears. Natural air enters the first stage through an air filter and mixes with a small amount of oil in the compression chamber while compressing the mixture to the interstage pressure. The compressed gas enters the cooling channel and comes in contact with a large amount of oil mist, thus significantly reducing the temperature. The cooled compressed gas enters the secondary rotor for a second compression, which is compressed to the final exhaust pressure. Finally, the compressor is discharged through the exhaust flange to complete the entire compression process.
