Reducer for Efficient Compressor: including an air filter; particles and a water separator, with semi-automatic emptying. Unit> high-quality maintenance: The threaded connection and fitting are made of brass, hardened steel. and stainless steel. Reliable and durable. Easy to clean. install and maintain: simply plug in the compressed air regulator. between the compressor and the consumer, pull the black knob and set the desired pressure. Easy to install and maintain. Pressure gauge settings compressed air: pressure setting range: 0.05 - 0.85 MPa, maximum setting pressure: 0.95 MPa. Operating temperature range: 5 - 60°C. Capacity from the filter cup to water: 60 cc. How it works: It effectively protects the compressed air system. from mechanical contamination and water and maintains working pressure. The pressure reducer allows even air discharge and smooth compressor operation. Extends the life of the machine.
