What's the difference between a Catch Can and an AOS?

A catch can is designed to catch and collect crankcase vapors, and remove them from the intake system. Most catch cans do not recirculate back into the intake system, they simply vent all crankcase pressure to the atmosphere. An Air Oil Separator is recirculated back into the intake, and is designed to vent the crankcase back into the intake system for a few reasons. The first reason being there is no unwanted smell that you would get from a VTA catch can. The second being that using an intake source on the AOS, you are constantly pulling vacuum on the crankcase and will "suck" the vapors out when in boost, deceleration or even at idle.
