120R-200S (Riser Mount) and 120R-200T (Tank Mount)
The 120R Series of dry and pre-action sprinkler system compressors offer two models: a convenient, time saving riser mount and a space saving vertical tank mounted design. This system utilizes Gast’s own oil-less rocking piston style 120R compressor, the most powerful rocking piston air compressor on the market. The 120R delivers industry leading flow performance, longer life, and better electrical efficiency compared to competitive models. Included with this system is a durable digital pressure switch to provide a wide system capacity all in one model. This switch is designed to meet NFPA-13 standards (for dry and pre-action fire sprinkler systems) for initial pump up time and is rated for 940 system gallons @ 40 PSI and 2259 system gallons @ 18 PSI, and has the ability to set cut in and cut out pressures with the touch of a button. Many thoughtful details throughout these designs.
