Compressed-air calculator
Sizing an air receiver (storage)
The air receiver is the system’s shock absorber: it carries momentary air demands that exceed compressor capacity until demand settles.
This calculator gives the volume required to ride through a given demand event without dropping below your minimum acceptable pressure.

SCFM reference = 1 bar abs (CAGI / ISO 1217). The receiver only supplies the net flow (demand − compressor make-up). V = (Q_net · t · P_atm) / (60 · ΔP).
