A.J. Antunes JD-2-RED Pressure Switch
The Antunes JD-2-RED Pressure Switch (P/N: 801111303) is a high-precision air differential switch engineered for critical monitoring in HVACR and industrial combustion systems. Featuring a distinct red spring, this auto reset pressure switch provides a versatile operating range of .1 to 24" w.c. (3 mm to 600 mm), making it an essential component for air proving, vacuum, and differential pressure applications. Built with a rugged die-cast aluminum housing, the JD-2-RED ensures long-term reliability in demanding environments. The unit includes a sensitive diaphragm and a Single Pole Double Throw (SPDT) snap-action electrical switch rated for 10 Amps, allowing for seamless integration into safety interlocking circuits. With 1/8" NPT connections and a visible ON-OFF indicator, technicians can easily verify system status at a glance. Whether you are searching for an Antunes 801111303 replacement or a dependable differential pressure switch for fan operation verification, the JD-2-RED delivers the accuracy and repeatability required for modern air management systems.
Key Benefits:- Wide Adjustable Range: The red spring allows for precise setpoint adjustments between .1" and 24" w.c.
- Industrial Durability: Constructed with die-cast aluminum to withstand harsh mechanical rooms and industrial settings.
- Clear Status Monitoring: Equipped with an integrated visible ON-OFF indicator for rapid diagnostic checks.
- Flexible Connectivity: Features dual 1/8" NPT ports for pressure, vacuum, or differential sensing.
- High Electrical Capacity: The SPDT snap-action switch handles up to 10 Amps at 125 VAC for robust control over burners and blowers.
- What is the difference between the JD-2-RED and the 801111303? They are identical units; 801111303 is the specific manufacturer part number for the JD-2 model equipped with the red spring.
- Can this switch be used for vacuum sensing? Yes, the Antunes JD-2-RED is designed to function as a pressure, vacuum, or differential air switch depending on how the 1/8" NPT ports are piped.
- Does this unit require manual resetting? No, this is an auto reset model that automatically returns to its original state once the pressure moves back across the setpoint.
