OL Plus Series
Oil Less - Riser Mounted Air Compressors
General Air Products’ newly improved OL Plus Series Oil Less Riser Mounted Fire Protection Air Compressors are the same compressors the fire sprinkler industry has come to rely on but with 30 years’ worth of experience based improvements built in! All of our OL Plus single phase standard units and low pressure units are UL 1450 listed for fire protection, fully automatic, and virtually maintenance free. We have added a 30” braided stainless steel flex hose to the riser mounting kit and pressure switch that were already included to allow for a fast and easy installation. Our standard OL Plus series units are single phase, pre-wired adjustable up to 60 psi and factory pre-set. Low pressure, High pressure, 3 phase and 50 Hz OL Plus Series units are available. While we do include a riser mounting kit these units can be wall or floor mounted as well.
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). Those models have been replaced by the new OL Plus units. 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. If you have any questions please contact us at 800-345-8207. New features on the OL Plus Series include: Adjustable setting up to 60 PSI, increased system capacity, 208 voltage availability, new riser mounting bracket, 30" stainless steel flex hose, decreased unit weight (by 25%), and integrated intake filters.
