Oil Lubricated Base Mount Air Compressors For Dry Pipe & Pre-Action Fire Sprinkler Systems
The L Plus Series base mount, oil lubricated fire protection air compressors are a rugged, old school style, workhorse of an air compressor. Single phase, three phase, and 50 Hz units are available. As with all of our fire protection air compressors, the L Plus Series is specifically engineered to pressurize dry and pre-action fire sprinkler systems according to the parameters of NFPA 13. They arrive ready for installation with specially formulated compressor oil, vibration pads, a 30″ stainless steel flex hose and union.
Range: The L Plus Series lubricated, base mounted fire protection air compressors can be used in dry sprinkler systems up to 2500 gallons in size.
Note: L Plus Series units do not include a pressure switch. Automatic operation requires the separate purchase of an AMD-2 Air Maintenance Device.
