Air compressor water pump pressure control switch
Pressure control switch used in refrigeration and compressor air system, adjust the equipment is high,low limit control and avoid the over-low suction pressure and over-high exhaust pressure.
It can start and stop refrigeration compressors and fans of condensers.
Pressure control can be used in Pneumatic, boiler, fire protection, ironing,hydraulic. pumps and other equipment
Pressure control with copper air-box connector, suitable for freon air, liquid and other non-corrosive media, with stainless steel air-box connector, it can be used with liquid ammonia etc corrosive gas or liquid system.
Pressure control is mainly used for negative-pressure environment,such as vacuum chamber used for vacum extraction in the process of the system pressure reaches the pump settings to stop work and start the vacuum pump is higher than set pressure.
