SCHWANK JS-0575-UL Air Proving Switch Overview
The SCHWANK JS-0575-UL is an air proving switch designed to verify adequate airflow in radiant heating and combustion air systems before allowing burner operation. Set at a differential pressure of .70″ W.C. (inches water column), this switch provides a critical safety interlock that helps protect equipment and ensures proper combustion conditions are met prior to ignition.
Key Features
- Air proving switch rated at .70″ W.C. differential pressure setpoint
- Designed as a direct replacement or OEM component for SCHWANK radiant heating systems
- Provides burner lockout protection when insufficient airflow is detected
- Helps ensure safe, reliable combustion system operation
- UL-recognized construction for added safety assurance
- Compact design for straightforward installation in tight equipment spaces
Application
This air proving switch is intended for use with SCHWANK radiant heating equipment. It monitors the pressure differential created by the combustion air blower and signals the control system only when proper airflow has been established — preventing unsafe ignition attempts and protecting both the equipment and the building occupants.
Why Choose the SCHWANK JS-0575-UL
As an OEM-specified component, the JS-0575-UL ensures compatibility and reliable performance within SCHWANK heating systems. Using the correct air proving switch maintains the integrity of the safety control circuit and supports compliance with equipment installation and service requirements.
