1. The screws of screw compressor are driven by hydraulic motor. The rotation of
screws creates suction and air starts to flow.
2. The air flows through intake filter and valve into the compression chamber.
3. Intake air is compressed between male and female screws. Oil is mixed with air
and injected into screws for lubrication and cooling.
4. The majority of the oil is separated from the oil-air-mixiture in a separating tank
in compressor block.
