L Series

Base Mounted - Oil Lubricated Air Compressors

The L Series base mounted, oil lubricated fire protection air compressors are a rugged, old school style, workhorse of an air compressor. Single phase, three phase, high pressure and 50 Hz units are available. As with all of our fire protection air compressors, the L Series is specifically engineered to pressurize dry and pre-action sprinkler systems according to the parameters of NFPA 13.

Range: The L Series lubricated, base mounted fire protection air compressors can be used in dry sprinkler systems up to 2500 gallons in size.

Note: L Series units do not include a pressure switch. Automatic operation requires the separate purchase of an AMD-2 air maintenance device.
