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.

A coalescence separator for separating liquid droplets from a gas flow has a gas inlet and a gas outlet. A multi-layer structure of a plurality of individual layers of a coalescence filter medium is arranged between the gas inlet and the gas outlet, wherein the coalescence filter medium is provided with a glass fiber paper with glass fibers. The individual layers of the coalescence filter medium each have an individual layer thickness of more than 0.8 mm and maximally 5 mm, a grammage of greater than 80 g/mand less than 500 g/m, and an air permeability of 350 l/ms to 1,800 l/ms. The multi-layer structure has between 2 and 80 of the individual layers.

Disclosed are: a separation element () of a liquid separator () for the separation of liquid from an aerosol; a separation medium (); a liquid separator (); and a method for producing a separation element. The separation element () has at least one separation medium () for separating at least the liquid, the separation medium being arranged circumferentially about an element axis () in at least one medium layer (). The aerosol is able to flow through the separation element () radially relative to the element axis (). At least one medium layer () has, on a radially inward circumferential surface, at least one channel-shaped indentation () extending axially to the element axis () to realize at least one channel () for separated liquid.

A filter holder for a filter element that has an oval-shaped cross section transverse to a longitudinal direction thereof, the filter holder including: a receiving section configured to receive the filter element; fluid inlet for allowing fluid to be filtered into the filter holder; fluid outlet for letting the fluid filtered out of the filter holder; the fluid inlet is arranged so the inflow direction of the fluid to be filtered into the fluid inlet is parallel to the longitudinal direction of the filter element; the fluid inlet has a guide member configured to deflect the fluid as it flows into the fluid inlet such that it flows around in a spiral in the filter element that can be received in the receiving section in order to separate particles contained in the fluid to be filtered on a wall of the receiving section with the aid of centrifugal force.
