The OL Plus Series fire protection air compressors cover 30 minute fill up times on sprinkler systems up to 1225 gallons in size. NOTE: As of 2012 we stopped manufacturing our OL Series fire protection compressors (light blue in color).

Do you still offer technical support for old oil less riser compressors?

You can still find technical information on the obsolete oil less riser mounted compressors in the “Additional Information” tab below and we continue to offer technical support for all of our units however any orders placed for the old model numbers are upgraded to the new OL Plus Units described on this page.

Reliable offers the Model QRM2 Quiet Riser Mount Air Compressor, providing a compact and quiet compressed air source for dry pipe and pre-action fire protection systems. Available in ¼ HP, ½ HP, and 1 HP, the Model QRM2 can be ordered with an integral one-gallon tank.

How are air compressors selected for installation?
