How long will it take to fill our compressed air receiver tank?
T = Time (Min)
V = Receiver Volume (ft^3)
P2 = Final Receiver Pressure (PSI)
P2 = Initial Receiver Pressure (PSI)
C = Compressor Production (CFM)
PO = Atmospheric Pressure (PSI) – Typically 14.7
**** Volume (ft^3) = Gallons / 7.48
Example 1: How long will it take for a compressor with an output of 84 CFM to fill a 240 gallon tank at 175 PSI?
Start by converting gallons to ft^3: 240 / 7.48 = 32.1
Then complete the equation:
T = 4.55 min
