Oil Mist Separator for Closed Crankcase Ventilation (CCV) Keeps diesel turbochargers and intercoolers running at peak performance.     The Alfdex oil mist separator is a unique product that uses the centrifugal separation technique to prevent unclean ventilated crankcase gases returning to the inlet of diesel engines. Installing an Alfdex oil mist separator means that oil droplets and soot are removed from the blow-by and returned to the oil sump. Only clean blow-by gases are then returned to the manifold. The Alfdex design combines Alfa Laval’s unparalleled expertise with industrial centrifugal separators, and Haldex know-how being an established supplier to the global automotive industry. The Alfdex unit is designed for diesel engines in the capacity range 5–16 litres. The Alfdex oil mist separator is sealed for life and requires no maintenance or service during the service life of the engine.
