Receiver:
The vessel used to contain compressed air, referred to as a ‘tank’ in the USA. As a general rule of thumb most systems need a minimum of a ‘one minute receiver’. Although wholly inaccurate, the following will provide the basis of most systems. 700 cfm compressor at 7 barg. 700/7 = 100 cubic ft receiver. 700 cfm compressor at 10 barg. 700/10 = 70 cubic ft receiver.

Refrigerated dryer:
A dryer which chills compressed air, forcing the air to produce condensate thereby drying it. See dryers.

Relief Valves:
A device fitted to receivers and the like that allows the system pressure to vent before the safe working pressure is reached.

RH (Relative Humidity):
Air has a natural ability to hold water. Its ability is dependent upon temperature and to a lesser degree pressure. Whenever air has absorbed as much water as it can hold, it is called saturated. Or even 100% saturated. In this condition it is ready to produce condensate, but not quite ready enough. Air in this condition has a 100% RH. If the air had absorbed only half as much water as it could theoretically hold, then the air would have a 50% RH.

Risk Analysis:
Risk is the probability of failure, and the term risk is often confused with the term ‘hazard’.
