The A.J. Antunes 8023204130 is a factory original air differential (vacuum) pressure switch from Antunes Controls. It is designed to detect changes in air pressure and actuate a control circuit when a specific differential is reached. This OEM part is commonly used in HVAC systems, ventilation equipment, and mechanical controls to support airflow monitoring and safety interlocks.
Key Features
- Factory designed differential vacuum switch for low pressure applications (approx. 0.40″ W.C.).
- Non adjustable pressure setting simplifies installation and ensures consistent performance.
- Single Pole, Double Throw (SPDT) switch contacts for reliable control signalling.
- 1/8″ NPT connection for standard HVAC tubing attachment.
- Compact, rugged design for use in ductwork, blower modules, filter pressure sensing, and general air pressure control tasks.
