Antunes Controls 8621204001 Pressure Switch

The Antunes Controls 8621204001 is a high-precision air differential pressure switch designed for critical monitoring of air flow and pressure differentials in HVACR systems. This Model JD-2 configuration features an adjustable range of .17 to 6 inches water column, providing technicians with the flexibility required for fine-tuning commercial ventilation and burner systems. Built with a manual reset mechanism and a SPDT (Single Pole Double Throw) switch, it ensures a positive lockout in the event of pressure deviations, preventing unsafe operation. The unit utilizes 1/4" barb connections for straightforward integration into existing pneumatic lines. Its rugged construction is engineered for long-term stability in high-demand environments, making it a reliable choice for interlock circuits and exhaust fan monitoring. By ensuring precise set-point accuracy, this pressure switch minimizes nuisance tripping while maintaining rigorous safety standards for air-handling units and industrial process controls.

• Manual Reset Mechanism: Provides a safety lockout feature that requires technician intervention after a trip, ensuring system faults are addressed.
• Field Adjustable Range: The .17" to 6" w.c. set-point range allows for versatile application across various static pressure requirements.
• SPDT Switch Configuration: Enables the control of two separate circuits or provides signaling for both normally open and normally closed operations.
• Reliable Sensing: Designed for high-accuracy detection of differential air pressure in commercial and industrial HVAC systems.

Common Questions

How do I adjust the set point on the Antunes 8621204001?
The set point is adjusted by turning the internal adjustment screw; use a calibrated manometer to verify the exact pressure at which the switch trips for precise HVAC pressure monitoring.

What is the purpose of the manual reset on this pressure switch?
The manual reset prevents the system from automatically restarting after a low or high-pressure event, ensuring a contractor inspects the equipment for underlying issues first.

Can this switch be used for both positive and negative pressure applications?
Yes, by utilizing the 1/4" barb ports correctly, the JD-2 can monitor positive pressure, vacuum, or the differential between two pressure sources.
