Coalescence separator, in particular for use in a crankcase ventilation system, crankcase ventilation system and use of a coalescence separator

摘要

The invention relates to a coalescence separator for separating liquid droplets from a gas flow, in particular for separating oil from a crankcase gas flow, comprising a gas inlet, a gas outlet and a multi-layer structure of a coalescence filter medium arranged between the gas inlet and the gas outlet, characterised in that the coalescence filter medium is an in particular wet-laid glass-fibre paper having a single-layer thickness of more than 0.8 mm and at most 5 mm, a basis weight of greater than 80 g/m² and less than 500 g/m², and an air permeability of the single layer of from 350 to 1800 l/m²s.
