Description
The A.J. Antunes 803113101 LGP‑H Low Gas Pressure Switch is a precision, OEM‑grade safety control component designed for accurate monitoring of gas pressure in commercial HVAC systems, gas‑fired furnaces, boilers, and other industrial applications. Engineered to operate within a pressure range of 1 to 7 PSI, this switch helps protect equipment and improve system reliability by breaking the electrical control circuit when gas pressure falls outside safe limits — preventing unsafe operation and potential damage.
Key Features
- Pressure Range: 1 – 7 PSI (Low Gas Pressure) — suited for sensitive gas monitoring tasks.
- Manual Reset: Ensures deliberate restart after a pressure fault for enhanced safety.
- SPDT Switch Contacts: Provides dependable switching for control and safety circuits.
- Standard NPT Fittings: 1/4″ pressure inlet and 1/8″ vent allow easy integration with gas line systems.
