A filter assembly for filtering particulate contaminants from a fluid comprises: a generally cylindrical filter unit with one end closed and the other end open; a filter head comprising a generally cylindrical sleeve extending generally horizontally an open end for receiving the open end of the filter unit with that has a vent port aligned with a vertical axis through an upper portion of the sleeve and a drain port aligned with the vertical axis extending through a lower portion of the sleeve; and a coupling for securing the open end of the filter unit to the filter head to seal the sleeve vent and drain ports; wherein loosening the coupling allows the filter unit to slide away from the filter head sufficiently to establish fluid communication between the sleeve vent and drain ports.
