Abstract: A filter assembly for separating and removing a liquid from a compressed fluid stream includes a filter element for separating the liquid from the fluid, a purge valve, and an elongated valve operator for actuating the purge valve. The top of the filter element has a shroud that decreases the flow area of the entering fluid stream to induce a vortex of the fluid, allowing the liquid to separate from the fluid. The purge valve is located at the bottom of the filter element for draining the separated liquid. The elongated valve operator axially extends through the filter element and is moveable by an actuating piston located at the top of the filter element, in response to elevated pressure in the filter assembly. The filtered air is dried through a desiccant body and then outputted from the filter assembly to be used in an air brake system.

The suction panel is formed to rotate with an axial direction of an air blowing fan or a direction perpendicular to the axial direction of the air blowing fan as a rotation axis to be coupled with or separated from the housing. Accordingly, a user may easily and intuitively separate the suction panel and falling of the suction panel, which may occur when the suction panel is separated, may be effectively reduced using a supporting unit disposed at the suction panel. Also, the housing and cover members which cover an outer perimeter of a lower portion of the housing may be coupled with each other by pressurizing the cover members toward the housing, thereby allowing the user to easily coupled the cover members.
