Supervisory Air Compressor

The Supervisory Air Compressor maintains a low-pressure air charge within the dry piping of a preaction sprinkler system providing continuous supervision of pipe integrity and enabling rapid detection of any pipe breach or leak before water is introduced into the system. In a double interlock preaction system, loss of supervisory air pressure is one of the two trigger conditions required for preaction valve activation, making a reliable, consistently performing air compressor critical to overall system functionality. Viking supervisory air compressors are engineered for continuous duty operation with automatic pressure regulation, low-pressure alarm signaling, and minimal maintenance requirements. Sized to maintain correct system supervisory pressure across a range of pipe volumes and compliant with NFPA 13 requirements for preaction system supervision.
