Air Compressors & Service

An air compressor increases the pressure of air that is otherwise at atmospheric compression levels. Air conditioners can be typified in a number of ways including their principle of operation, number of stages, capacity, pressure limits and cooling method.

Air can be compressed by a reciprocating, rotary screw or turbo operation compressor, operating in either a single or multi-stage configuration. Air compressors will be rated at low, medium, high and super high air pressures with a typical rating being represented as FAD (CFM) 11.1 cfm @ 7.5 Bar which can be described as free air delivery of 11.1 cubic feet per minute at 7.5 bars of atmospheric pressure. In addition, air compressors can be described as low, medium or high capacity and are generally air or water cooled.

Air compressors are commonly used to fill storage cylinders, to supply air to divers, to drive HVAC control system valves, for pneumatic tools, for filling tyres and for many large-scale industrial processes. Different types of air compressors are appropriate for different uses, most often based on the pressure of the air to be delivered.

Air compressor units require regular qualified maintenance and service to ensure their safe and efficient operation. Many suppliers will also be able to provide or recommend maintenance services.
