Product Description:

The Expello electronic drain valve is the perfect method to create a clean, dry, and long-lasting air system. This automatic drain valve can be used on semi-trailers, tanker trailers, and other applications. The Expello valve works by activating every twenty minutes, where the valve automatically shoots a one-second purge of the air system.

This valve will also function to keep air brakes on trailers from freezing up by purging the excess air when the unit is powered
