An air receiver tank is an integral and important part of any compressed air system. Typically a receiver tank is sized at 6-10 times the flow rate of the system. So, if a compressor has a rating of 25 scfm at 100 psig, the receiver tank should be 150 cubic feet, minimum. In a compressed air system, a receiver tank provides the following benefits like a water reservoir provides water during times of drought and stores water during the wet times, an air receiver tank compensates for peak demand and helps balance the supply of the compressor with the demand of the system.
