Antunes Controls 8023202115 Pressure Switch

The Antunes Controls 8023202115 Pressure Switch is a fixed-setpoint, air differential pressure switch engineered for precise monitoring in HVAC and commercial kitchen ventilation systems. Factory-calibrated to 0.2" W.C., this non-adjustable pressure switch ensures reliable proving of air flow or filter pressure drops without the risk of field tampering. It features a Single Pole Double Throw (SPDT) switch configuration, allowing for versatile wiring in either normally open or normally closed circuits. The unit is equipped with a 1/8" NPT connection for secure pneumatic integration. Built for durability in demanding industrial environments, this Antunes pneumatic switch is a standard replacement for maintaining safety protocols in combustion air proving and exhaust systems. Its compact design and high-accuracy diaphragm make it a critical component for technicians requiring consistent HVAC pressure monitoring and repeatable actuation points in low-pressure differential applications.
