Oil Flooded Screw Compressor
Twin screw shaped meshing rotors are mounted in a figure of eight shaped housing, which has suction and discharge ports at either end.
As the rotors turn they form a space that traps gas, the space travels down the length of the housing, and because of the profile of the screws, is compressed as it goes.
Oil is flood injected into the compression space to lubricate the bearings and screws, and to absorb the heat of compression. The oil and compressed gas mixture subsequently passes into a de-oiling vessel.
The oil is then cooled and filtered and goes back round the cycle once again.
