It is often used to automatically remove accumulated water at the bottom of pipelines, refrigerated air dryers, oil-water
separators, air storage tanks and the bottom of various air filters. It can be installed in places where it is inconvenient to
discharge sewage manually, such as high places, low places, and narrow places; especially in places with large gas consumption and
frequent water discharge, it can prevent the compressed air from being forgotten due to artificial drainage. Water is re-polluted.
