Open Crankcase Ventilation Filters OCV series



Especially for engines with a power of up to 100 megawatts our oil mist separators ensure top separation performance and functional safety – thus, they can be used even for critical applications, such as a potentially explosive atmosphere. With a residual oil quantity of less than 5 mg/m³, the statutory limit values of the TA Luft are significantly undercut. When required, we provide all models in an ATEX certified design.

Safe and environmentally friendly

Our substantial separation performance of more than 99 % not only protects the environment but also your employees. Since the oil content of the combustion gases is significantly reduced, slippery surfaces, possible ignitions and oil in the atmosphere can be dealt with successfully.

Optimized crankcase pressure

You can best prevent an inadmissible pressure increase within the crankcase by using our UPF-OCV oil mist filters. With a regulated fan, the required underpressure inside the crankcase can also be regulated accurately for variable operating conditions. In addition, the low pressure loss of our UPF oil mist separators also saves costs by ensuring low power consumption.

Guaranteed reliability, even on the high seas

The specific requirements for engine operation on the high seas are given special consideration in our products. For use on ships or offshore platforms, we are the only manufacturer worldwide to offer oil mist separators approved by Germanischer Lloyd (GL) and RINA.

Worldwide unique: Approved by Germanischer Lloyd and RINA

Especially in the cruise ship industry, an increased environmental awareness, stricter obligations and requirements on cleanliness and safety lead to an increased need in oil mist separation. Being a pioneer in the industry, we have reacted to this early: As the worldwide only manufacturer, we provide oil mist separators which are approved by several international classification societies.
