Antunes Controls 8101111303 Pressure Switch

The Antunes Controls 8101111303 High Gas Pressure Switch is a critical safety component designed for precise gas pressure monitoring in commercial boilers, industrial furnaces, and large-scale HVAC systems. This HGP-G model operates within a setpoint range of 8 to 35 inches water column (wc), providing reliable circuit interruption when system pressure exceeds safe operating limits. Built with a SPDT switch and a manual reset mechanism, it requires a deliberate physical intervention following a trip, ensuring the underlying cause of the pressure spike is addressed before the system returns to service. The housing features a durable die-cast aluminum base and a 1/4" NPT bottom inlet for a secure, leak-free connection to gas lines. For technicians managing combustion processes, this switch offers high accuracy and rapid response times (open high pressure), protecting downstream equipment from potential damage and ensuring compliance with safety standards for high pressure gas switches.

• Precise Pressure Control: Adjustable setpoint range of 8-35" wc allows for fine-tuning based on specific combustion equipment requirements.
• Enhanced Safety: The manual reset feature prevents automatic cycling after a fault, requiring a technician to verify system integrity.
• Versatile Integration: Features a Single Pole Double Throw (SPDT) configuration, allowing for flexible wiring as a high-limit safety or for remote alarm signaling.
• Industrial Durability: Robust construction with a 1/4" NPT connection designed to withstand the rigors of mechanical rooms and commercial kitchens.

• Is this switch field-adjustable? Yes, the Antunes 8101111303 allows for field adjustment of the pressure setpoint within the 8" to 35" wc range to match your specific application.
• Can this be used for low gas pressure applications? No, this is a high gas pressure switch designed to open the circuit on a pressure rise; for low-pressure monitoring, a different model in the Antunes series is required.
• What is the maximum surge pressure for this unit? This model is typically rated for a maximum surge pressure of 15 PSI.
