PureVent
Optimice la fiabilidad del motor con Alfa Laval PureVent 2.0. Este separador centrífugo elimina de forma eficiente hasta el 99.9% de la neblina de aceite de los gases de escape del cárter, evitando una presión excesiva en el cárter y minimizando la contaminación por aceite. Mantenga una operación estable del motor y reduzca las necesidades de mantenimiento.
Limpieza superior de gases del cárter para optimizar el rendimiento del motor
- Eficiencia de limpieza excepcional: elimina hasta el 99.9% de la neblina de aceite, superando a los ciclones, trampas de aire y filtros tradicionales
- Permite la liberación responsable de aire prácticamente libre de aceite a la atmósfera. El aceite recuperado puede ser reutilizado
- Intervalos de servicio prolongados (hasta 16,000 horas): menos mantenimiento, sin cambios frecuentes de filtro ni residuos peligrosos
- Diseño flexible para adaptarse a las necesidades específicas a bordo o en plantas de energía
- Rendimiento contrastado en aplicaciones exigentes, mejorando la calidad del aire y reduciendo el consumo de aceite lubricante
Las emisiones del cárter plantean grandes desafíos: la neblina de aceite contamina el mar y ensucia las cubiertas y los espacios del motor.
Alfa Laval PureVent 2.0 aborda este problema mediante la separación centrífuga de alta velocidad, eliminando la neblina de aceite y las partículas de los gases del cárter.
De este modo, puede liberar de forma segura el gas limpio a la atmósfera o recircularlo hacia el turbocompresor.

Features that set PureVent apart
High-speed disc stack centrifugation (7200 rpm)
The graph shows the grade efficiency of oil mist separation at flows of 100 m3/h and 200m3/h
The advanced technology delivers outstanding and steady cleaning efficiency, removing up to 99.9% of oil mist from crankcase gas. That means cleaner air output and less risk of engine pressure build-up.
Flexible design
Open and closed system compatibility, whether releasing cleaned gas to the atmosphere or recirculating it to the turbocharger, PureVent 2.0 keeps engine spaces cleaner and prevents turbocharger fouling. This flexibility ensures optimal operation in both power plant and marine applications.
Scalable setup (option)
The system can easily run two units in parallel for flows above 200 m³/h, managed by a shared variable frequency drive (VFD), maintaining stable pressure and separation efficiency even in demanding environments. This means fewer maintenance interruptions and consistent engine protection.
How it works
PureVent 2.0 uses high-speed centrifugation to remove oil mist, soot and unburned fuel from crankcase gas.
The separator unit has a stack of 185 rotating discs made from lightweight polymer. Crankcase gas enters at the bottom and passes into the disc stack. Centrifugal force presses oil and soot out. This leaves air virtually oil-free, so you can responsibly release it into the atmosphere.
For enhanced environmental performance, the collected oil can be recirculated through the separator and used again, in example in the engine lubrication system.
The collected oil may also be drained for use in shipboard incinerators or stored for proper disposal.
Select your ideal crankcase ventilation system design:
Open design – releases oil-free crankcase gas directly into the atmosphere
Closed design – re-circulates clean gas to the turbocharger, eliminating all crankcase emissions and the risk of turbocharger fouling

Capturing oil mist from the engine blow-by is a clean win for EPASA
Centrais Elétricas de Paraíba, or EPASA,is the owner of two diesel power plants near João Pessoa, a coastal city at Brazil’s eastern tip. With a total installed capacity of around 340 MW, the plants form one of the largest thermoelectric power facilities in the region. EPASA keeps a watchful eye on their environmental impact and operating efficiency, and this was the reason for installing 40 units of Alfa Laval PureVent 2.0. With this unique air separator, the plants have eliminated an oily environment and reduced lube oil consumption.
