Oil Injected Air Compressor

Oil Injected compressor are widely used in various industries to provide
compressed air power. CMN oil injected screw air compressor adopts patented
shaft sealless design to ensure that the air end will never leak oil. The
unique single-screw type air end achieves twelve times of compression in one
rotation, with high efficiency. The ultra-high machining accuracy allows the
air end to achieve good sealing and lubrication effects by spraying only a
small amount of lubricating oil so the oil content can be less than 2ppm to
meet most usage requirements.

OIL INJECTED SCREW COMPRESSOR VS RECIPROCATING PISTON COMPRESSOR
Piston air compressors use the piston to reciprocate in the cylinder to
compress the air. They have high noise and vibration and many wearing parts.
After the piston rings are worn, the air volume will decrease causing the
decreased efficiency.

The oil injection screw compressor mainly consists of a screw and star wheels
to form a compression chamber. The air compression process is completed through
the rotation of the screw which has higher requirements for processing accuracy
because higher accuracy means higher volumetric efficiency. The noise and
vibration are small, the unit has basically no wearing parts so the maintenance
cost is low.

HOW DO OIL INJECTED AIR COMPRESSOR WORK？
The main components of an oil free vs oil injected compressor are the air end,
motor, oil and gas separation tank and cooler. Since the oil requires a higher
temperature to ensure its good lubricity, the oil injected air compressor is
generally air-cooled. The air is filtered by the filter element and then sucked
into the air end for compression.

Lubricating oil is injected into the air end for lubrication and sealing. The
compressed oil and gas mixture is separated by the separation core in the oil
and gas separation barrel to get compressed air with an oil content of less
than 2ppm. After being cooled by the air-cooled cooler, the high-temperature
oil returns to the compression air end and circulates continuously.
