Hengst AS819M Crankcase Ventilation Oil Separator

The Hengst AS819M is a precision-engineered crankcase ventilation oil separator designed to efficiently separate blow-by gases from engine crankcase emissions. This high-quality separator ensures optimal engine performance by cleaning contaminated gases before they re-enter the intake system.

Key Features:

• Effectively separates oil mist from blow-by gases during engine operation
• Returns separated engine oil back to the oil circulation system, reducing oil consumption
• Delivers cleaned gases to the intake tract, protecting critical components like intercoolers and turbochargers
• Helps reduce emissions and improve combustion efficiency
• Designed as a direct replacement service part for reliable long-term performance

This oil separator plays a crucial role in the crankcase ventilation system by filtering blow-by gases that escape through piston rings during combustion. By preventing oil-laden gases from contaminating the intake system, it helps maintain engine cleanliness, extends component service life, and ensures compliance with emission standards.
