Crankcase ventilation filter/pre-separator

A filter for removing liquid contaminants from an emissions stream, comprising:

• a housing defining an internal chamber and including i) an upstream inlet port in the housing for directing the emissions stream into one axial end of the chamber, and ii) a downstream outlet port in the housing for directing the emissions stream out of another axial end of the chamber, and iii) a drain port in the chamber intermediate the inlet and outlet ports for directing liquid contaminants in the fluid emissions stream outwardly from the chamber;
• filter media disposed in the chamber for separating liquid contaminants from the emissions stream, the filter media being insertable into the chamber through the inlet port, and
• a support device supporting a downstream end of the filter media at a predetermined axial location within the chamber, the support device including a frame fixed within the housing downstream from the drain port and an aperture, the support device preventing liquid contaminants from migrating downstream along the walls of the housing and allowing a contaminant free emissions stream to pass through the aperture and downstream to the outlet port, wherein the liquid contaminants in the emissions stream agglomerate in the media and flow outwardly from the drain port.
