A coalescer is provided minimizing trade-offs among high removal efficiency, low pressure drop, long service life, and small size.

Space optimized coalescer

An oil fill cap for an internal combustion engine replaces a standard cap and provides separation of air and oil in a separation zone within the cap body. The cap body defines a plurality of passages therethrough, including an upstream passage, and first and second downstream passages meeting at a separation junction. The cap body defines a separation zone at the separation junction and receiving the air/oil mixture from the engine through the upstream passage, and sending separated air to the first downstream passage, and sending separated oil to the second downstream passage.

Oil fill cap with air/oil separator

A diesel engine crankcase ventilation filter is provided by a flat low profile filter housing extending in a horizontal plane and having an upper planar horizontal surface, a lower planar horizontal surface, and side surfaces extending between the upper and lower surfaces. A planar horizontal flat panel filter element extends parallel to the upper and lower surfaces. The housing has an upper plenum between the flat panel filter element and the upper surface, and a lower plenum between the flat panel filter element and the lower surface, an inlet receiving oil and air from the diesel engine and supplying same along an inlet path to the upper plenum to flow downwardly through the flat panel filter element to the lower plenum, a first outlet outputting air along a first outlet path from the lower plenum, and a second outlet outputting oil along a second outlet path from the lower plenum.

Flat low profile diesel engine crankcase ventilation filter

A flat panel filter element is provided for a diesel engine crankcase ventilation filter having a flat low profile filter housing extending in a horizontal plane. The flat panel filter element has media, including coalescing media, spanning a horizontal supporting and sealing perimeter border frame and passing flow downwardly therethrough.

Multi-peripheral perimeter sealed flat panel coalescing filter element

A diesel engine crankcase ventilation filter is provided by a flat low profile filter housing having an inlet receiving oil and air from the diesel engine, an outlet returning air to the engine, a drain returning separated oil to the engine, and a flat panel filter element in the housing receiving the oil and air from the inlet, separating the oil from the air, and passing the air to the outlet and passing the oil to the drain.
