Oil-Less Riser Mount Air Compressors For Dry Pipe & Pre-Action Fire Sprinkler Systems

General Air Products’ newly improved OL Plus Series Oil-Less Riser Mount Fire Protection Air Compressors are specifically designed to fill dry and pre-action systems to supervisory pressure within 30 minutes per NFPA 13. All of our OL Plus single phase standard units and low pressure units are UL 1450-VDUR listed for fire protection, fully automatic, and virtually maintenance free. We include a 30” braided stainless steel flex hose and a riser mounting kit 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 also available. While we do include a riser mounting kit – these compressors can be wall or floor mounted as well.

NOTE: As of 2021 we redesigned our OL Plus Series fire protection air compressors. Obsolete models have been replaced by the new models below. If you need technical information on the obsolete oil less riser mount compressors click here.

The OL Plus Series Oil Less Riser Mount Fire Protection Air Compressors cover 30 minute fill up times on sprinkler systems up to 1225 gallons in size.
