Oil mist separators


Development, production and services for oil mist separation in demanding applications. From a single source.



Due to the design of internal combustion engines, a gaseous mixture enters the crankcase, which must be removed to prevent a permanent increase in pressure. This blow-by gas contains not only unburned fuel and pollutants but also finest oil droplets. These are almost completely separated by UT99 oil mist separators and returned to the oil circuit. UT99 oil mist separators ensure improved occupational safety and make a massive contribution to environmental protection.

Less costs and a higher engine reliability

By integrating our highly efficient oil mist separators, sensible components are reliably protected against contamination. This means you not only benefit from an overall reliable system, but also from extended maintenance intervals and lower life-cycle costs.

Increased efficiency

With gas-powered engines, our highly efficient filtration of blow-by gas leads to a permanently increased efficiency if combined with the closed crankcase ventilation (CCV). For fuels escaping in an open crankcase ventilation (OCV), are returned to the combustion chamber. Today we are already thinking about tomorrow; therefore, our products are designed so that further efficiency increases can be achieved by design optimisations of the intake section and the turbocharger.

Improved health and safety – also on cruise ships

In addition to the contamination of sensitive components, our technology also prevents the formation of lubricating films and thus contributes to a safe and clean work environment. It also meets the especially high requirements on safety and cleanliness on cruise ships. We obtained the respective certificates by several international classification societies.

Significantly below legal requirements

With our separation efficiency of 99.9 %, it is ensured that the limit values of TA Luft (Technical Guideline for Air Pollution Control) are undercut. We can even ensure compliance with future, more stringent specifications without a problem.

Environmentally friendly and future-proof

While the legislation for car engines has standardised closed crankcase ventilation (CCV) for decades, so far this technology is only used occasionally for large industrial engines. Here, international legislative changes, regulations and standards are foreseeable as well. Therefore, we are prepared: Already today, applications developed in cooperation with us and our technologies, are significantly eco-friendlier and ensure compliance with future specifications.
