Trane SWT2291 Pressure Switch

Trane SWT2291 Pressure Switch

The Trane SWT2291 is a commercial-grade SPNO negative pressure switch engineered to maintain critical air pressure differentials in demanding HVAC and industrial environments. This Trane OEM part features a single-pole, normally open contact configuration, providing precise activation when vacuum levels drop below set parameters. With an operational range of -0.5 to -2.5 inches water column (WC) and field-adjustable set points, it offers the flexibility required for cleanrooms, isolation wards, and exhaust fan monitoring. Built for longevity, the housing is designed to withstand the rigors of mechanical rooms, while the 1/4-inch male quick connect terminals and 3/16-inch tubing ports ensure a streamlined installation for service contractors. Rated for 3A at 12 VAC and 28/125 VA pilot duty, this negative air pressure switch is essential for preventing the cross-contamination of airborne particles and verifying proper inducer or exhaust operation in high-efficiency systems.

Key Benefits:
  • OEM Precision: Genuine Trane SWT2291 ensures exact factory calibration and seamless integration with existing building automation systems.
  • Adjustable Set Points: Features a wide pressure range (-0.5 to -2.5 in. WC), allowing technicians to fine-tune the trip point for specific duct or room requirements.
  • Robust Electrical Rating: Equipped with SPNO contacts rated for industrial pilot duty, ensuring dependable switching for dampers and fans.
  • Industrial Durability: Engineered to operate reliably in temperatures ranging from -4°F to 19°F, suitable for unconditioned mechanical spaces.
Common Questions:

What is the contact orientation for the SWT2291?
This is an SPNO (Single-Pole, Normally Open) switch, meaning the circuit completes and the switch closes only when the specific negative pressure threshold is reached.

Can this switch be used for positive pressure monitoring?
No, the Trane SWT2291 is specifically designed as a negative pressure switch for vacuum applications. Using it for positive pressure may result in inaccurate readings or component failure.

What size tubing is required for the static pressure ports?
This unit is designed for use with standard 3/16-inch flexible plastic or rubber tubing, ensuring a tight seal for accurate differential sensing.
