The Viking Model H-1 Maintenance Air Compressor is an electric motor-driven solution for maintaining air pressure in dry sprinkler systems. Engineered for efficiency, this air-cooled, oil-less compressor is perfect for applications where system pressures need to exceed 20 PSI. It provides consistent air supply through an adjustable pressure switch and features a factory-installed pressure relief valve to prevent pressures from exceeding 75 PSI.Key benefits of the Model H-1 include a carbon steel mounting bracket with stainless steel adjustable straps (compatible with pipe sizes from 2″ to 6″), self-lubricating pistons, permanently lubricated bearings, and stainless steel valves for enhanced longevity. The compressor is equipped with thermal protection that automatically resets, ensuring operational safety. It’s also proof-tested to withstand up to 250 PSI for hydrostatic testing after installation.
