Antunes Controls 801111321 Pressure Switch

The Antunes Controls 801111321 is a versatile Air Differential, Vacuum, and Pressure Switch designed for precision monitoring in commercial HVAC and industrial process applications. This SPDT air pressure switch features an adjustable set point range of .1 to 10 inches water column, allowing for exacting field calibration. Constructed with a durable 1/8 inch NPT connection and integrated Harrison Connector, it ensures a secure, leak-free interface in high-vibration environments. Technicians rely on this adjustable pressure switch for its ability to sense positive, vacuum, or differential pressure across heat exchangers, blowers, and filtration systems. Its robust diaphragm design provides consistent repeatability across its WC range, maintaining system safety and operational efficiency. The electrical configuration supports simplified wiring for direct replacement or new installations, making it a critical component for differential pressure sensing requirements in demanding mechanical systems.

• Wide Operating Range: Adjustable set points from 0.1" to 10" W.C. accommodate diverse system static pressure requirements.
• Multi-Functional Sensing: Capable of monitoring air differential, vacuum, and positive pressure within a single device.
• Durable Construction: Heavy-duty housing and 1/8" NPT threads withstand professional-grade installation torques.
• Specialized Connectivity: Equipped with a Harrison Connector for rapid, reliable electrical termination.
• Control Accuracy: High-sensitivity SPDT switching provides reliable feedback for fan proofing and airflow verification.

Common Questions

How do I adjust the set point on the 801111321?
The set point is adjusted by removing the cover and turning the internal adjustment screw. Use a calibrated manometer to verify the exact trip point against the inches water column scale.

Can this switch be used for both positive and negative pressure?
Yes, this versatile unit is engineered to function as a vacuum switch, pressure switch, or differential switch depending on which port the tubing is connected to.

What is the purpose of the Harrison Connector?
The Harrison connector provides a specific plug-and-play interface common in specialized commercial equipment, ensuring a vibration-resistant electrical path compared to standard terminals.
