Selecting the right air receiver for a compressed air system may seem straightforward. 'I have a compressor, so I can connect any receiver to it.' However, in practice, this approach can lead to a range of operating problems and reduce the efficiency of the entire system.
morePressure vessels are widely used in industry and manufacturing plants, in compressor rooms and in pneumatic and gas installations, as well as in refrigeration and fire protection systems. As they operate under pressure and may pose a risk to health and safety, they are subject to technical inspection by the Office of Technical Inspection (UDT), which sets out requirements for the safe operation of pressure equipment.

The pressure vessel is connected to the compressor via a connection nozzle located on the shell or the dished end of the receiver. If the receiver is large, or if several devices are connected to it simultaneously, it may have more than one inlet connection. This allows additional compressors to be connected, reducing the time required to fill the receiver or achieve the desired pressure.

While most devices can be supplied directly from a compressor, the pressure delivered is not uniform. Pressure fluctuations occur in line with the operating frequency of the pistons or rotors, resulting in uneven operation of the equipment.
