Default crank case evacuation

I am thinking of using a 12v "3 vane" horn compressor to evacuate my crank pressure gasses. It is supposed to maintain a steady 7 psi.
Has anyone attempted using an apparatus like this horn compressor? I am going to use it "backwards" so air is pulled from the crank case.
I have questions. I am not a air/fluid engineer. Hahaha.
Does pressure eminating from a source get expended at each "tank"? If I wash the bad air in a series of oil seperation tanks will the total source pressure be divided over the number of tanks I use? Like voltage in an electrical circuit?
If I reduce the amount of oil in the vapors by traps and filters will I be able to exhaust through the compressor to the atmosphere? What would happen if I sent the clean compressed air back to the IM in a closed circuit?
I wonder if this compressor has to run all the time or can I set it up to turn on after a certain rpm is reached?
I am thinking of using a small oil cooler in an upside down position and placing the "horn" compressor after the air comes out of the cooler and through a filter. My other idea is to serpentine some small tubing (venturi speed). I am thinking there has got to be a way to "tap" the tubes at the bottom of each run to allow for oil drainage. Maybe like a pin prick? Anyone know how to drain yet still retain the vacuum and air speed?
My idea is if I can put sharp turns into the oily air stream the air will dive through the turns but the drunken oil will react to late and hit the outer tube wall and slime its way to the bottom of the troft??
Good ideas or industrial experience graciously rec'd. Thanks. RFT
