AD402 is often used to automatically remove water from the bottom of pipes, refrigerated air dryer, oil-water separator, air storage tank and various air filters. It can be installed in places that are not convenient for manual sewage discharge, such as high, low and narrow places; especially in places with large air consumption and frequent water discharge, it can prevent the compressed air from being re polluted by condensed water due to forgotten manual drainage.
