Description
The Radium Engineering AOS-R (Air Oil Separator - Recirculating) is a precision-engineered crankcase ventilation solution designed to separate oil vapors and contaminants from crankcase gases before they enter the atmosphere. This universal VTA (Vent to Atmosphere) configuration features advanced internal baffling, CNC-machined construction, and a compact design suitable for a wide range of applications where clean venting is required.
Part Number
- 20-0819 - AOS-R, Universal, VTA
Key Features
- Vent to Atmosphere Configuration: Vents clean air to atmosphere after oil separation
- Universal Application: Adaptable to various vehicles and engine configurations
- Advanced Oil Separation: Multi-stage internal baffling for superior oil vapor capture
- CNC-Machined Construction: Precision-machined from 6061-T6 aluminum
- Anodized Finish: Durable, corrosion-resistant black anodized coating
- Compact Design: Space-efficient profile for tight installations
- Easy Maintenance: Drain valve for simple oil removal without disassembly
- Multiple Ports: Versatile port configuration for various plumbing setups
How It Works
The AOS-R uses advanced internal baffling to separate oil vapors from crankcase gases. Clean air is vented to atmosphere while captured oil drains back to the engine or collects in the canister for periodic removal. This prevents oil contamination of intake components and maintains optimal engine performance.
Application
Universal fitment for:
- Turbocharged and naturally aspirated engines
- Custom crankcase ventilation systems
- Applications requiring vent to atmosphere configuration
Note: Universal application requires custom plumbing and mounting. Hoses, fittings, and mounting hardware sold separately.
