How long will it take to fill our compressed air receiver tank?

Posted on April 5, 2023

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

“Best Aire has performed exceptionally well with everything they have been asked to do. I have had them rebuild 3 of my 800hp centrifugal compressors over the past 6 years and the machines operate just like new. Any spare parts that I need or want they find them, from turbo oil to inlet filters to transducers. The staff is very easy to talk to, quick to return phone calls or emails and propose ideas to help with energy reduction. Thank you!” – R.M.
