Description
The A.J. Antunes 803112501 Low Gas Pressure Switch is a robust OEM control component engineered for precise low gas pressure monitoring and safety control in commercial HVAC and gas-fired equipment systems. Designed with a 1″–6″ water column (W.C.) pressure range, this switch detects when gas pressure drops below a set threshold and manually resets to help safeguard equipment and prevent unsafe operating conditions.
Key Features
- Pressure Range: 1″–6″ W.C. – ideal for low gas pressure detection and safety shutdown applications.
- Manual Reset: Requires manual reset after a low-pressure event to confirm safe restart.
- SPDT Output Contacts: Reliable switching for control and safety circuits.
- Standard NPT Ports: 1/4″ inlet and 1/8″ vent make installation with existing gas lines straightforward.
- Durable Build: Die-cast housing for long service life in industrial environments.
