Closed Crankcase Ventilation Filters CCV series


Closed crankcase ventilation and highly efficient oil mist separation – a profitable duo



While gas engine manufacturers have long benefited from the many advantages of the complete reduction of the crankcase emissions (“blow-by“), more and more diesel and dual-fuel engine manufactures start relying on this technology as well.

Oil Mist Filter Series UPF-CCV

Blow-by filters for closed crankcase ventilation of combustion engines

Less costs, improved health and safety and greater environmental protection – there are many good reasons to use closed crankcase ventilation. Years of experience and designated references are proof of the reliable and flawless interaction of the components, so that your engines and customers benefit permanently from all positive aspects.

Increase of efficiency

With the high content of unburnt gaseous hydrocarbon in blow-by, the efficiency for gas engines increases by up to 0.7 % – with a guaranteed residual oil content of less than 1 mg/m³. Thus, turbocharger contaminations and build up of deposits within the entire intake section are reliably prevented.

Market leader in cogeneration gas engines

The quality and reliability of our products have already convinced already numerous companies in the industry. By dealing intensively with the special requirements of oil mist separators used in cogeneration plants, we know the technical challenges and have provided our customers with customised solutions for many years.

Worldwide unique: CCV up to 32 megawatts

For almost two decades, we have been the experts for closed crankcase ventilation, and we are the only manufacturer in the world that offers proven oil mist separators for engines up to 32 megawatts – upon request even with type approval.
