Antunes Controls 8221210034 Pressure Switch Els PW 17895 or a failing inducer motorThe Antunes Controls 8221210034 is a precision engineered Air Differential Pressure Switch designed for high accuracy sensing in HVACR applications. Operating within a set point range of 0. 05 to 1. 0" W. C., this diaphragm actuated switch is critical for monitoring filter status, proof of airflow, and pressure drop across coils. The unit features SPDT (Single Pole Double Throw) circuitry, allowing for flexible wiring configurations in both normally
