Air Flow Switches

Air flow switches detect moving air and provide a switching or alarm output for ducts, fans, filters, air handlers, radon mitigation systems, and ventilation equipment. Products in this category span vane-operated duct switches, adjustable paddle switches, thermal air flow switches, alarm indicators, and switches with high or low alarm set points.

Applications include:

  • Fan operation proving
  • Low air flow alarms
  • Filter and air handler monitoring
  • Duct airflow status indication
  • Ventilation and mitigation system alerts

Represented products from Dwyer Instruments and Omega Engineering support both simple airflow proving and more configurable alarm or relay output requirements.
