Product Description

Air Differential Pressure Switch 20-200Pa Adjustable Micro- Pressure Air Switch

Description

The differential air pressure switch is used to control the differential pressure of the air for filters, fans, air ducts, air-conditioning and ventilation systems. This pressure switch is especially suitable for control and safety functions in air-conditioning systems, providing the fan stop signal and dirty filters signal.
