LT Plus Series

Tank Mounted - Oil Lubricated Air Compressors

General Air Products’ LT Plus Series tank mounted lubricated air compressors are integrally mounted on ASME coded air receivers. They arrive ready for installation with a quart of compressor oil and a mounted pressure switch. LT Plus Series units can be adjusted up to 60 psi and leave our factory set for 30 psi on and 40 psi off. Single phase, three phase, high pressure and 50 Hz units are available.

As with all of our fire protection air compressors, the LT Plus Series is specifically engineered to pressurize dry pipe and pre-action sprinkler systems according to the parameters of NFPA 13. Tank mounted air compressors are recommended as the ideal type of compressor for dry pipe sprinkler applications. We highly recommend a tank mounted air compressor where an accelerator is in use (see our model OLRTK for an alternative).

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

Note: An AMD-1 air maintenance device is required by code with all tank mounted fire protection air compressors. Multiple dry valves (no more than 3) may be supplied from a single tank mounted compressor when using our AMD-1 on each individual system.
