Description
The Kromschroder 84444900 Air Pressure Switch is a sensing and control component used in burner and airflow safety circuits. It operates by detecting changes in air or flue gas pressure through a diaphragm mechanism that activates electrical contacts when a preset threshold is reached. Installed in combustion air paths, fan assemblies, and safety monitoring lines, it ensures proper airflow verification before system operation continues. Positioned within HVAC systems’ control and safety circuits, it supports pressure monitoring, assists in operational safety checks, and contributes to stable and controlled system performance.
