Answer: The water separator, air filter, pressure reducing valve and oil mist collector are collectively called the three major pneumatic components. The assembly formed by connecting the three major components without pipes is called a triplex. The three major components are indispensable air source devices in most pneumatic systems. They are installed near the air-using equipment and are the final guarantee of compressed air quality. The installation order of the three major components is the water separator, air filter, pressure reducing valve and oil mist collector according to the air intake direction. In use, one or two components can be used according to actual requirements, or three components can be used.
