This drain will sit on the bottom of the air filter and on the inside of several dryer models. There is an internal screen that helps filter out dirt/debris that may have been removed by the filter to ensure it does not get clogged and stay open. As the water builds up in the bottom of the bowl, the drain will raise to drain out the moisture automatically. Once the water has been removed, it will close automatically to not waste compressed air.
