That video demonstrates the huge disparity in how most cans work and are designed. Look close in that video and see it also has oil being pulled up and out the outlet.
Watch from the 20 minute mark on here to see just how ineffective most cans are in comparison to our internal design.
That is why we provide evacuation suction full time so evacuation is taking place at all times VS only a short period with most cans. It is common to confuse "catachcans" by lumping them into the same pile. Ours are true air/oil separating crankcase evacuation systems. Our dual valve systems provide just that, full time evacuation and the most effective separation on the market period.
