Under unsuitable mains conditions, operation of the compressor can have an adverse effect on other equipment. No interference should be expected if the mains network impedance is less than 0.3Ω (ohms). Generally, the maximum permissible impedance will not be exceeded if the compressor is supplied from a domestic power outlet or a sub-distribution cabinet with a rated current of 25A.
The compressor is an air cooled, oil lubricated reciprocating compressor working on the single stage principle of compression.
Atmospheric air is drawn in through the air filter into the compression chamber of the compressor block. The downward movement of the piston creates a vacuum. When the piston has passed the bottom dead centre, the air drawn into the cylinder is compressed by the upward movement of the piston. At the same time the inlet valves close and the outlet valves open.
The compressed air is forced through a check valve into the air receiver. The check valve prevents the compressed air flowing back from the air receiver to the compressor block after shutdown.
