Radium Engineering Universal Air Oil Separator (AOS-R)

20-0819 AOS-R, Universal, VTA
The vent-to-atmosphere air-oil separator has 2 side (inlet) ports. This is great for dual bank engines that have 2 crankcase vent ports. NOTE: For single crankcase vented engines, simply plug one of the inlet ports with Radium Engineering 14-0351. The VTA AOS-R features one giant non-restrictive outlet that is over 183% larger than the inner diameter of the 10AN inlets. This increase in volume slows air flow allowing contaminants to fall out of suspension. Additionally, contaminants are trapped with a diffuser permitting the oil sludge to fall back into the catch can preventing overspray in the engine bay. Furthermore, it is a dual stage design (located in the inlet and outlet). These free flowing chambers do not create any flow restriction.

This air/oil separator is designed to collect crankcase gasses and allow collected oil to drain back into the engine via gravity. Gasses are then vented to the atmosphere out the top of the AOS VTA. Universal installation.
