nope surprises me too and surprises customers when I tell them to add vacuum pump system.
with big motor and 4 stage suction you may get a negative atmospheic pressure in crank case of 5 to 6 inches. not enough to help anything except oil return and it helps a bunch if you have one stage plubmed for drain back from on top. . ed
