Dwyer Instruments PG-7000-153-P1 Pressure Switch

The Dwyer Instruments PG-7000-153-P1 is a gas pressure switch designed for accurate monitoring and control of low-pressure air and gas systems. This differential pressure switch operates within a 1 to 30 inch water column range, making it suitable for HVAC applications involving airflow proving, filter monitoring, and burner system safety. Equipped with an SPDT snap switch, it provides reliable and fast contact response for consistent system control.

This HVAC pressure switch features a 4" W.C. deadband to prevent short cycling and maintain stable operation under fluctuating pressure conditions. The vertical mounting configuration ensures proper diaphragm response and accurate switching performance. Contractors commonly use this Dwyer pressure switch in duct systems, combustion air proving, and ventilation monitoring where dependable pressure sensing is critical for safe equipment operation.
