PureVent system


Alfa Laval’s compact air separator designed to remove oil mist from crankcase gases with a cleaning efficiency of 99%. Occupying 30 litres of space in handling any engine size, the system reportedly has low power consumption and is maintenancefree. The oil is returned to the sump via a drainpipe, thereby reducing losses and releasing only clean air to the atmosphere.
