Resideo AP5027-30 Airflow Switch 0.05"-12" Water Column SPDT Compressor FM

The Resideo AP5027-30 Airflow Switch is a stable device for measuring and controlling the airflow in HVAC systems. It is equipped with a differential pressure sensing mechanism with a setpoint range of 0.05" to 12" WC thus enabling accurate airflow measurement. It can work at 1/2 PSI and it has 1/4" compression fitting which makes it easy to retrofit into existing systems. This switch has an SPDT contact and can therefore energize or de-energize a compressor based on the airflow conditions. This switch is most suitable for commercial and industrial HVAC systems as it enhances the performance of the systems by guaranteeing the right airflow.
