How To Size An Air Receiver Tank | Sizing Formula & More
The approximate ideal volume of the receiver tank can be calculated by modifying the sizing formula to: V = t C pa / (p1 – p2) = (1 minute) (20 CFM) (14.7 PSI) / ( (175 PSI) – (90 PSI)) = 3.46 ft3. = 25.9 gallons. However, this formula works best for large reciprocating air compressor systems with variable airflow.
