Features: It can relief by air inlet throttle and stabilize voltage by force balance. The filter can effectively remove impurities and debris in the compressed air to extend tool life and performance. Clockwise to increase pressure and anticlockwise reduce pressure. It is recommend to use the ISO VG32 lubricating oil, has a good atomization performance to lubricate components of the system. Usage scenarios: air compressors, pneumatic tools, gas connection installation, effective filtration of air moisture.
