A.J. Antunes 8024204046 Pressure Switch

The A.J. Antunes 8024204046 Pressure Switch is a professional-grade air differential pressure switch engineered for field-ready reliability in HVAC and industrial combustion systems. This SPDT (Single Pole Double Throw) switch provides an adjustable set point range from 0.17" to 6.0" WC, allowing for precise calibration across a variety of pressure-sensitive applications. Technicians often utilize this model for monitoring air handling units, managing filtration system differentials, and ensuring safety in forced-air environments. Built with 1/8" female NPT connections, it ensures a secure, leak-proof mechanical interface. As an FM Approved component, it meets rigorous safety standards for high-stakes environments where accurate air pressure control is non-negotiable. Whether you are replacing a failed Antunes pressure controller or integrating a new safety interlock, the 8024204046 offers the structural integrity and repeatable performance required by commercial service contractors.

• Precise Set Point Adjustment: Features a versatile 0.17 to 6.0 inches water column range to accommodate diverse system requirements.
• Industrial Build Quality: High-impact housing and robust internal diaphragm designed for long-term cycling in demanding plant environments.
• High Compatibility: Standard 1/8" NPT porting simplifies integration into existing pneumatic lines and manifolds.
• Certified Safety: Carries FM Approval, making it suitable for hazardous or high-spec commercial HVACR installations.
• Versatile Wiring: The SPDT switch configuration allows for both normally open and normally closed electrical logic.

What is the maximum operating pressure for the 8024204046?
This switch is designed for low-pressure air differential monitoring; always verify that your system’s maximum surge pressure does not exceed the manufacturer’s rated burst pressure to prevent diaphragm damage.

Can this switch be used for gas pressure monitoring?
The A.J. Antunes 8024204046 is specifically rated as an air differential switch. For combustible gas applications, ensure you are selecting a model specifically rated and sealed for fuel gases.

How do I calibrate the 0.17" to 6.0" WC range?
Adjustments should be made using a calibrated manometer. Turn the adjustment screw to the desired set point while the system is under load to ensure accurate trip timing and precision air monitoring.
