Crankcase ventilation systems
Crankcase ventilation systems from MANN+HUMMEL work reliably and efficient. They separate the oil droplets from the blowby gas and the oil is returned to the oil sump. This protects the intake system from contamination with oil and extends its service life. In addition to the ProVent² series from the MANN+HUMMEL standard portfolio, we also offer customers individual and customized solutions.
