Abstract: A coalescence separator for separating liquid droplets from a gas flow is provided with a multilayer structure of a coalescence filter medium as a finest stage of the coalescence separator. The multilayer structure of the coalescence filter medium is arranged between a gas inlet and a gas outlet and surrounds a cavity. A product of an air permeability of the coalescence filter medium and a grammage of the coalescence filter medium amounts to at least 16 g/m*s and maximally 100 g/m*s. The coalescence filter medium is a glass fiber paper. The coalescence separator is used, for example, as a main oil separator in screw compressors.

Abstract: A separating apparatus for separating liquid from gas has a housing with a connection device for connecting to a connection head of a machine along a connection axis. The housing has a gas inlet and a gas outlet surrounding the connection axis. A separating medium inside the housing separates gas inlet from gas outlet. A liquid collection chamber inside the housing at a clean gas side surrounds connection axis and gas outlet. A liquid drain leads out of the liquid collection chamber. Gas outlet and liquid drain lead out of the housing at a side provided with the connection device. A pipe section arranged inside the housing surrounds circumferentially the connection axis and forms at least partially a radially inner boundary of the liquid collection chamber. The pipe section leads to the gas outlet. The pipe section is functionally separated from mechanical force-transmitting connection elements of the connection device.
