A.J. Antunes 8024206202 Pressure Switch

The A.J. Antunes 8024206202 Pressure Switch is a heavy-duty SPDT air differential pressure switch engineered for precise monitoring in commercial HVAC and industrial venting systems. This model JD-2 variant features an adjustable set point range of .17" to 12" W.C., providing the sensitivity required for proving air flow and monitoring filter pressure drops. Built with a rugged die-cast aluminum housing, it utilizes a single-pole double-throw electrical configuration to allow for both normally open and normally closed circuit logic. Connectivity is handled via a bottom 1" male NPT and a side 1/8" female NPT inlet, ensuring versatile integration into existing hard-piped lines or flexible tubing setups. As an FM approved pressure switch, it meets stringent safety standards for combustion and ventilation applications, offering technicians a reliable solution for high-static environments where accuracy is non-negotiable.

Key Benefits for Technicians:

• Wide Adjustment Range: Covers 0.17 to 12 inches of water column, making it suitable for a broad spectrum of duct static pressure and differential air pressure applications.
• Industrial Durability: The robust housing and high-quality diaphragm ensure stable pressure switch calibration even in environments with frequent cycling.
• Flexible Mounting: Dual NPT connection points (1" Male and 1/8" Female) simplify retrofitting in tight mechanical rooms.
• Reliable Switching: The SPDT contacts facilitate easy integration with building automation systems (BAS) or local alarm circuits.
• Safety Compliance: FM approval ensures the component satisfies code requirements for critical air proving and safety interlock circuits.

Common Questions:

How do I adjust the set point on the 8024206202?
The set point is adjusted by turning the internal adjustment screw; use a calibrated manometer to verify the exact trip point against the 0.17-12" W.C. scale during commissioning.

Can this switch be used for both positive and negative pressure?
Yes, this air differential pressure switch is designed to sense the difference between two pressure sources, making it ideal for monitoring pressure across fans, filters, or coils.

What are the electrical ratings for the SPDT contacts?
Typically, these JD-2 series switches support 15 Amps at 125/250/480 VAC, though you should always verify the specific load requirements of your controller or motor starter.
