Oil separators - clean blow-by gases

Reducing the oil content of blow-by gases also reduces the number of particles in the exhaust gas that are created by combustion. This reduction increases the service life of exhaust gas purification components such as particle filters or catalytic converters significantly.

Before the blow-by gases from the crankcase ventilation are fed back to the intake air, the oil must be filtered out to prevent tar-like deposits from forming on the turbocharger intake ducts or the intake air cooler.

MANN+HUMMEL oil separators provide optimum protection for components of the air intake system against contamination, which would affect their function and damage them. In addition, the high level of separation reduces oil consumption.

MANN+HUMMEL develops and produces oil separators as stand-alone components or as parts integrated into systems such as valve covers and oil filter modules.
