Air Receiver Sizing Calculator

Written by Matt Milbury. Posted in Calculators

This calculation uses the air consumption rate of the instruments and determines the size of an air receiver based on the time required to meet a minimum pressure. The minimum pressure is generally the low pressure set point of a compressor. The initial pressure is the design pressure the receiver. The calculation is displayed symbolically as:

\(Size_{gallons} =  \frac{Pressure_{Atmospheric}\times Time (Flow_{out} - Flow_{in})} {Pressure_{Initial} - Pressure_{Final}}\)

If the compressor only runs when the low level pressure is met, then the Flowin would equal zero.
