1/4" compressed air-water separator with pressure gauge for compressor and compressed air tools Compressor pressure regulator <p>Function: The oil water separator can effectively reduce or maintain air pressure. It performs vacuum compression by introducing air to remove impurities, moisture, and pollutants from pneumatic equipment.</p> <p>Features: The solid brass filter element is durable and corrosion-resistant; the transparent filter cup allows you to monitor the oil-water status in real time. And you can adjust the pressure with the push button.</p> <p>Parameters: Pressure adjustment range: Up to 10 bar / 1 MPa. Operating temperature range: 5 ℃ ~ 60 ℃.</p> <p>Quick coupling: 1/4" female thread connection; 2 1/4" male thread quick couplings are included.</p> <p>Wide application: The oil water separator is widely used for air compressors, pneumatic tools, gas connections, and efficient filtration of air humidity.</p>
