Description
The Cleveland Controls AFS-298 Air Pressure Switch is a sensing and safety control component used to monitor positive, negative, or differential air pressure within compatible equipment in HVAC systems. Commonly installed in furnaces, ventilation systems, and air proving applications, this switch responds to changes in airflow conditions by opening or closing an electrical circuit at designated pressure levels. It operates as part of the unit’s control and safety assembly, helping verify proper airflow before allowing the connected heating or ventilation part to operate. This pressure switch is typically used during servicing or replacement of airflow monitoring controls.
