A.J. Antunes 8102111305 Pressure Switch

The A.J. Antunes 8102111305 Pressure Switch is a high-performance RHGP-G gas pressure switch engineered to provide critical safety monitoring for commercial and industrial combustion systems. Specifically designed as an automatic reset high gas pressure switch, this device protects and optimizes the performance of burners, boilers, and ovens by monitoring for over-pressure conditions that could lead to equipment failure or unsafe operation. Featuring a robust 5-35" wc adjustable range, it allows technicians to precisely calibrate the 150% maximum manifold pressure threshold required for diverse HVACR applications. The SPDT electrical contact (Single-Pole Double-Throw) provides reliable circuit interruption, while the 1/4" NPT connection ensures a secure, leak-free installation into the gas train. Encased in a durable Nema 4 enclosure, this unit is built to withstand harsh environments, offering superior moisture and dust protection for long-term system integrity. By integrating this HVAC safety switch, operators ensure continuous compliance with industrial safety standards, effectively preventing nuisance shutdowns and catastrophic pressure spikes.

• Enhanced System Safety: Automatically interrupts electrical control circuits when gas pressure exceeds the calibrated 5-35" w.c. setpoint.
• Industrial-Grade Durability: The Nema 4 enclosure protects internal components from water spray and dust, making it ideal for demanding mechanical rooms.
• Precise Field Calibration: Features an adjustable dial for accurate pressure monitoring, ensuring the switch matches specific burner or boiler requirements.
• Minimized Downtime: The automatic reset function restores the circuit once pressure returns to safe levels, reducing the need for manual intervention.
• Universal Compatibility: Standard 1/4" NPT threading and SPDT switching logic allow for seamless integration into most commercial gas trains.

• Where is a high gas pressure switch typically installed? It is usually mounted downstream of the safety shut-off valves and the gas pressure regulator to monitor the maximum allowable pressure entering the burner.
• Can I use this switch for low gas pressure detection? No, this model (RHGP-G) is specifically designed to sense rising pressure (High Pressure). For falling pressure detection, an RLGP-G low gas pressure switch should be used.
• How do I set the correct pressure threshold? Most commercial standards suggest setting the high gas pressure switch to approximately 125% to 150% of the burner's rated manifold pressure at high fire.
