The oil-water separator can discharge through air intake throttling and stabilize the tension through force balancing. The filter can effectively remove impurities and debris from the compressed air to extend the tool life and performance. Clockwise to increase pressure and counterclockwise to increase pressure. The compressor moisture separator is recommended to use ISO VG32 lubricating oil. It provides good atomization performance to lubricate system components. Usage scenarios: air compressors, pneumatic tools, gas connection installation, effective filtration of air moisture.
