1、Pressure Control: The recommended operating pressure is 0.1‑0.85Mpa, so the pressure regulator enables easy adjustment over the pressure. 2、Simple Operation: Pull up on the top button and rotate clockwise to increase pressure, or rotate counterclockwise to release pressure. 3、Better Filtering: The air compressor filter can effectively filter out the small particle and dust in the air, ensuring clean air flowing. 4、Easy in Draining: Moreover, the drainer supports differential pressure drainage and automatic drainage, which can handle the waste inside. 5、Quick to Install: Comes with a compact size and a light weight as well, the filter and pressure regulator is very convenient to install.
