Air Pressure Regulator: Oil-water separator can relief by air inlet throttle and stabilize voltage by force balance. Clockwise to increase pressure and anticlockwise reduce pressure Air Filter Regulator: The filter can effectively remove impurities and debris in the compressed air to extend tool life and performance. It can filter small particles, keep the air clean Air Tool Accessories: Compressor moisture trap is recommend to use the ISO VG32 lubricating oil, has a good atomization performance to lubricate components of the system High Precision: The 1/4 inch compressed air pressure regulator is made of high-quality metal and plastic, with a stable and clear structure that can be used in a temperature range of -10~60℃ Usage Scenarios: Air compressor regulator is widely used for compressed air in air compressors, pneumatic tools, and gas interface devices, effectively filtering of air moisture, Weight: 0.7275254646 pounds, Manufacturer: Nikou
