AULISS Atmospheric Oil-injected Screw Compressor Working Principle

The working principle of an atmospheric pressure oil-injected screw compressor involves several key steps. Initially, atmospheric air enters the compressor through an intake filter. Inside the oil injected screw air compressor, a pair of interlocking rotors with helical screw profiles draw in the air and compress it as they rotate. During compression, injected oil serves multiple purposes: sealing the gaps between rotors to prevent air leakage, cooling the compressed air, and lubricating moving parts for smooth operation. The compressed air-oil mixture then moves to a separator where oil is removed, ensuring clean compressed air output. Finally, the air is stored in a receiver tank for distribution to various applications. This process enables efficient compression and delivery of compressed air for industrial and commercial use.
