A.J. Antunes 8101111407 Pressure Switch

The A.J. Antunes 8101111407 Pressure Switch is a critical safety component engineered for high-precision gas pressure monitoring in industrial burners and commercial boilers. As a Manual Reset SPDT High Gas Pressure Switch, the HGP-G model acts as a limit control, breaking the electrical circuit if gas pressure exceeds the calibrated setpoint. This unit operates within a 10 to 60 inch water column (WC) range, providing a wide field-adjustable window for diverse combustion system requirements. The 1/4 inch NPT connection ensures a standardized, leak-free integration point for standard gas manifolds. Designed for high-cycling environments, this OEM Antunes 8101111407 switch features a Single Pole Double Throw (SPDT) configuration, allowing for both safety lockout and remote alarm signaling. For HVACR technicians and commercial contractors, this switch provides the necessary FM approved and UL listed reliability required for code-compliant gas train installations and repairs.

Key Technical Benefits:

• Field-Adjustable Setpoints: Allows for precision tuning between 10" and 60" WC to match specific OEM equipment requirements.
• Enhanced Safety Logic: The manual reset feature ensures a technician must inspect the appliance before the system can resume operation after a high-pressure trip.
• Robust SPDT Contact: Provides versatile wiring options for cutting power to the gas valve while simultaneously activating a diagnostic light.
• True OEM Compatibility: Direct replacement for Antunes HGP-G series, ensuring original mounting and electrical alignment.
• Industrial Durability: Constructed to withstand the temperature fluctuations and vibrations common in commercial mechanical rooms.

Common Questions & Technical Support:

How do I adjust the pressure setpoint on the 8101111407?
Remove the top cover and use the internal adjustment dial to align with your required "WC. Always verify the trip point with a calibrated manometer during commissioning.

Can this switch be used for low gas pressure applications?
No, the 8101111407 is an HGP (High Gas Pressure) model designed to trip on a rise in pressure. For low-pressure monitoring, an LGP series switch should be utilized.

What is the purpose of the 1/4" NPT connection?
The 1/4" NPT female pipe thread is the industry standard for gas pressure switches, allowing for direct mounting to the gas line or via a sensing tube.
