Antunes Controls 8023204130 Pressure Switch

The Antunes Controls 8023204130 is a high-precision air differential pressure switch engineered for critical airflow monitoring in commercial HVACR applications. Factory-calibrated to a 1.4" W.C. set point, this non-adjustable pressure switch prevents field tampering, ensuring consistent safety and operational performance across high-cycle duty environments. Featuring an SPDT (Single Pole Double Throw) contact configuration, it allows for versatile wiring as either normally open or normally closed, providing reliable feedback for burner control, fan proving, or filter status monitoring. The 1/8" NPT threaded connection ensures a secure, leak-proof mount into standard pneumatic lines. Built for durability in demanding industrial mechanical rooms, this differential air switch is a standard drop-in replacement for failed pressure sensors in specialized combustion or ventilation systems where precise set points are required for system interlock circuits.

Key Benefits

• Fixed Set Point Protection: The 1.4" W.C. factory setting eliminates the risk of field adjustment errors, maintaining system design integrity.
• Versatile SPDT Logic: Allows for simultaneous control of primary equipment and remote alarm or status monitoring.
• Durable Mechanical Design: Engineered to withstand the rigors of commercial furnace and cooling applications with high repeat accuracy.
• Standardized Fitment: The 1/8" NPT connection provides broad compatibility with existing pneumatic fittings and pressure ports.

Common Questions

Can the 1.4" W.C. trip point be adjusted in the field?
No, this unit is a fixed-set, non-adjustable model designed to maintain strict factory specifications for safety and compliance.

What is the primary function of the SPDT contacts in this switch?
The SPDT contacts allow you to either break a circuit upon pressure drop or complete an auxiliary circuit for a status light or BMS notification.

Is this switch compatible with water or oil pressure monitoring?
No, the 8023204130 is specifically designed for air differential pressure and should only be used in air or non-combustible gas applications.
