SCHWANK JS-0576-AA Air Proving Switch – .85″ W.C.

Description

SCHWANK JS-0576-AA Air Proving Switch

The SCHWANK JS-0576-AA is an OEM air proving switch designed to verify adequate combustion airflow before and during burner operation. Set at a differential pressure of .85″ W.C. (water column), this switch provides a critical safety interlock that confirms proper air pressure is present in the system — preventing ignition or shutting down the burner if airflow is insufficient or lost.

Key Features

• OEM SCHWANK replacement air proving switch
• Factory-set differential pressure setpoint of .85″ W.C.
• Monitors combustion air pressure to ensure safe burner operation
• Acts as a safety interlock — interrupts burner operation if airflow is inadequate
• Direct OEM replacement for compatible SCHWANK radiant heating systems
• Durable construction for reliable long-term performance in commercial and industrial heating applications

Application

The JS-0576-AA air proving switch is a genuine SCHWANK replacement part engineered for use with SCHWANK radiant heating systems. It is installed in the combustion air circuit and continuously monitors differential pressure to confirm that the blower or fan is delivering the required airflow. If pressure drops below the .85″ W.C. threshold, the switch opens the control circuit to safely shut down or prevent burner ignition, protecting both the equipment and occupants.

Why Choose OEM SCHWANK Parts?

• Ensures compatibility and proper fit with SCHWANK heating equipment
• Maintains system safety certifications and warranty compliance
• Precise factory-calibrated setpoint for accurate pressure sensing
• Reduces troubleshooting time with guaranteed drop-in replacement performance
