Description
The Williams Comfort Products 7734 is a precision-engineered SPDT (Single-Pole, Double-Throw) air differential pressure switch designed for reliable monitoring and control of air pressure differentials in HVAC and combustion systems. With a wide sensing range of 0.17 to 6 inches water column (“WC), this switch is well suited for a variety of applications including proving airflow, monitoring filter status, and verifying draft inducer or combustion air blower operation.
The 7734 features a 1/4″ compression fitting and 1/8” NPT connections, making it straightforward to integrate into existing pneumatic or air-sensing circuits. Its SPDT switching action provides both normally open and normally closed circuit options, offering maximum flexibility for control wiring configurations.
