Monnier airline filters are built to ensure solid and liquid contaminants are removed from compressed air.  All Monnier filters are engineered with the exclusive Whirl-Away design which creates high centrifugal force with low pressure drop.  the whirling action forces all liquids and solids against the bowl wall causing them to run down below the quiet-zone baffle where they can be drained out.  The air then flows through the element where the smaller particles are removed, and the filtered air passes downstream.  The leak proof drain valve has an o-ring seal that can be opened and closed without tools.
