Oil bath air filter Questions

[greg g]

The air path is the key. The design makes the incoming air turn 180 degrees above the oil. The air makes the turn, but any stuff it's carrying, succumbs to gravity and falls into the oil getting trapped there. The fiber and gauze upper filter is for the larger chunks.  The upper filter depends of aereation and heat to make a vapor that when shut down rises in the filter to refresh the gauze and fiber part. So by changing to a thicker oil in the bottom, you may be defeating the creation of that vapor, lessening the upper filters effectiveness. The incoming air does not pass through the oil. Its job is impoundment of contaminants being pulled from the air flow.

I guess this is a duplicate of a similar post I did earlier in this thread.  The principle s still apply.
