A.J. Antunes 8102111102 High Gas Pressure Switch 8/4" WC 1/4" NPT Auto Reset

The A.J. Antunes 8102111102 High Gas Pressure Switch is used in HVAC systems. It has an 8/4” WC setting and a 1/4” NPT connection. This switch operates on an auto reset mechanism and resets itself when the high-pressure condition is no longer present. If the gas pressure in the system gets to the level specified to turn the switch on, the gas supply to the equipment is cut. This averts possible harm to equipment such as compressors, valves and the piping system. It has the advantages of increasing equipment’s life, safety from explosion or fire, and low maintenance since frequent breakdowns are eliminated.
