Receiver Tanks.
Receivers perform several functions in a compressed air system. The receiver dampens
pulsations from reciprocating compressors, acts as a reservoir to take care of temporary demands in excess of
compressor capacity, and prevents frequent loading and unloading of the compressor. The receiver may also
act as a separator. Since the air is cooled and its velocity reduced, some of the moisture still in the air will
condense and fall to the bottom of the receiver where it can be removed by a trap or manual valve.
