Trane SWT3820 Pressure Switch an essential component of the HVAC systems that is used for measuring pressure of air. Setting at 1.75 PSI opens and 1.94 PSI closes, the switch helps to provide control over the air flow in the system, it is compact yet strong and is ideal to apply in any HVAC application, usually installed in air handling units and HVAC systems, this maintains pressure levels and increases the efficiency and durability of systems and reduce any possible damages. This is done by switching on or off depending on the pressure it detects to protect equipment and improve the system reliability. This design makes it possible to achieve high accuracy in performance, which is beneficial in power conservation
