Air Compressors

An air compressor is a machine that compresses air by reducing its volume and increasing its pressure. The compressor usually uses a pump run by an electric motor that will compress the air. The compressed air is produced by means of a piston and flows through a directional valve either to be stored in a receiver or used to power air tools or accessories. A pressure switch is used to turn the compressor ON and OFF. While in the ON position it will make the air compressor start automatically when the air pressure is too low and stop it when it reaches the set pressure. A regulator and a gauge allow adjustment of the outlet flow of air.

When shopping for an air compressor, remember the air compressor must be big enough to do the job of handling peak loads without undue strain and waiting for the compressor to build up to the required pressure. Select an air compressor that will do the job and allow time between pumping cycles to permit ample cooling. Do not buy a compressor that is too small.
