Fire Sprinkler Design info for Air Compressors

How To Size An Air Compressor:

To size air compressor multiply system volume x .012.

Example: 550 gal. * .012 = 6.6 CFM.

or

CFM = (SYS VOL x 40) / (30 x 7.48 x 15)


How to determine time to fill system with air:

Convert gallons to cubic feet – 1 gallon = .13368 f3

Divide system cubic feet by compressor CFM

Example: 550 * .13368 = 73.53 f3

73.53 / 6.6 = 11.14 minutes to fill system
