Doug, To properly size the air compressor, you would multiply the dry system volume by .012 This converts the capacity (in gallons) to cubic feet per minute of free air capacity.
This calculation should give you the proper amount of air capacity needed to re-charge your dry system to 40 psi in 30 minutes. Ray Vance Chief Engineering Tech. Wayne automatic Fire Sprinklers, Inc.

When the air compressor fails, customers often go to the cheapest compressor. We then have problems with the compressor running several times a day, and problems with the noise of the compressor. Any suggestions?
