Receiver Sizing

The “How To’s” of Compressed Air
One gallon per rated cubic foot? Never! This rule of thumb, though popular and easy to remember, does not take system events into account. Receivers are sized to accommodate large intermittent system air demand, a standby compressor start, local high rate of flow requirements and insulation of critical pressure users. The object of each case is: to prevent a compressor start, maintain pressure in the system while a compressor starts, servicing demand from storage separate from the main system, and to operate the system at lower pressures, respectively.

In the central compressor configuration, avoid placing any receiver capacity upstream of dryers or filters. Receiver capacity should always be installed downstream of air treatment to avoid surges across this equipment that might result in carryover to the system
