These compressors are suitable when medium pressures are required. They provide a simple system with minimal moving parts which equates to more reliable system with less maintenance involved. Screw compressors work on the basis of two intermeshing rotating screws with minimal clearance between each screw fin, they draw in air and squeeze it up along the screw with air getting compressed tighter the further along the screw its drawn until it reaches the discharge port, it is here that it is delivered out of the compressor. This requires oil to be sprayed in with the air to relieve friction and wear; some of this lubricant will make its way into the air system so it is removed by later oil separation units.
Types of Electric Lubricated Screw Compressors
a. EN Series Compressors
b. EG Series Compressors
These are the most common and most evidently used compressors for compressing air. When a single cylinder is used to compress air, the piston moves back drawing the air from the stroke in one direction. This will build up pressure and it can cause uneven air supply. As the piston is moving back drawing more air. It is always good to have double acting piston construction. This uses both the sides of piston and this will compress on both strokes in one revolution resulting in smooth air supply.
