The air is drawn in by means of a filter and passes through a modulating proportional valve that regulates the air delivery according to the demand. This valve automatically maintains the working pressure at constant levels.
Therefore, the air enters the compression chambers or vanes that the stator, the rotor, the vanes and the covers have formed. This rotor is installed eccentrically to the stator and is equipped with longitudinal grooves in which the blades slide. It is the centrifugal force that pushes the blades against the stator’s wall.
An efficient oil injection system guarantees a perfect holding among the moving parts, cooling and lubrication. An oil film on the stator’s inside surface prevents the moving parts from wearing by avoiding a direct contact with the blades.
Air compression is triggered by the volume reduction of the vanes in the stator during rotation. By passing through mechanical and coalescing separation stages, the mixture of compressed air and oil is purified until the maximum oil carry-over in the air does not exceed 3 ppm (parts per million).
Finally the air is cooled in the radiator and the condensate is eliminated by a condensate drain.
Mattei tank mounted air compressors offer small air users quiet continuous duty air compressor options with integrated air storage. Air receiver tanks provide reserve power for heavy air demands, greater moisture removal, and the ability to store air and turn off the motor for extended periods. Comprehensive integrated tank mount designs feature the same durable construction and simple reliable operation that make Mattei air compressors ideal for small enterprises, craftsmen and workshops desiring quiet operation, superior performance and great value.
