Radium Engineering AOS-R Universal Air/Oil Separator RAD20-0819

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. Installation instructions available at www.radiumauto.com

The Radium Engineering AOS-R Universal Air/Oil Separator is designed to manage crankcase ventilation gases in a wide range of automotive applications. It captures oil carried in crankcase vapors before those gases are vented, helping reduce oil discharge into the engine bay and surrounding atmosphere. The separator is intended for universal installation and can be incorporated into custom or performance-oriented engine ventilation systems.

Collected oil drains back into the engine through gravity, minimizing the need for frequent manual draining when installed correctly. Crankcase gases exit through the top of the separator, making the AOS-R suitable for vent-to-atmosphere configurations. Its compact automotive design supports flexible placement, while the Radium Engineering construction is suited to custom installations where reliable crankcase vapor management is required. Installation instructions are available from Radium Engineering at www.radiumauto.com.
