A.J. Antunes JD-2-PURPLE Pressure Switch
The A.J. Antunes JD-2-PURPLE Pressure Switch is a high-precision, industrial differential vacuum and air pressure switch engineered for sensitive monitoring in HVAC and combustion safety systems. This OEM air proving switch features a specialized purple spring calibration, supporting an adjustable set point range from 0.1 to 10 inches water column (W.C.). Designed with a single-pole double-throw (SPDT) snap-action switch, it provides reliable auto-reset functionality for airflow verification, filter monitoring, and fan interlock safety logic. The rugged die-cast aluminum housing ensures durability in demanding environments, while the 1/8" NPT connection ports and dual-scale indicator (inches and millimeters) allow for precise field adjustments. Whether used for differential pressure, vacuum, or air pressure applications, this compact switch offers exceptional repeatability and accuracy for professional HVACR maintenance and equipment protection.
Key Benefits:- Precision Monitoring: Features a calibrated purple spring for a sensitive 0.1 to 10" W.C. operating range.
- Industrial Durability: Housed in a heavy-duty die-cast aluminum enclosure to resist vibration and environmental wear.
- Clear Diagnostics: Includes a visible ON-OFF indicator and dual scales for rapid visual status checks and easy setup.
- Versatile Application: Ideal for airflow proving, combustion safety systems, and air handler interlocks.
- Automatic Operation: Equipped with an auto-reset mechanism to maintain system safety without manual intervention.
- What is the purpose of the purple spring in the JD-2 model? The purple spring indicates a specific pressure range of 0.1" to 10" W.C., making it suitable for low-pressure differential and vacuum sensing.
- Can this switch be used for both vacuum and pressure? Yes, the JD-2-PURPLE is designed to handle differential, vacuum, and air pressure applications with dual 1/8" NPT ports.
- How do I adjust the set point on this air proving switch? Remove the hexagon cap at the top of the indicator stem and use a screwdriver to turn the adjustment screw to the desired setting on the dual scale.
