An annular filter element and sealing element for an oil separator of a crankcase ventilation system, the filter element has a covering surface extending parallel to a direction of flow, together with at least one cover element covering surface in at least some regions. An oil separator is taught having the filter element with at least one pressure control valve controlling crankcase pressure and has a valve closing body that operates in conjunction with a valve seat. The sealing element having at least one radially sealing region that is configured to act in the direction of the radius of the annular filter element, and at least one axially sealing region that is configured to act in the direction of the longitudinal axis of the annular filter element.

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.

Coalescence separator, in particular for use in a compressed air compressor system, compressed air compressor system, and use of a coalescence separator

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.

A ring filter element has a filter medium body flowed through radially form an interior of the filter medium body to an exterior of the filter medium body. A bypass valve is provided that is adjustable between a blocking position, separating a raw side at the interior of the filter medium body from a clean side at the exterior of the filter medium body, and an open position, connecting the raw side of the filter medium body with the clean side of the filter medium body. The bypass valve is arranged in an axial direction of the filter medium body at least partially external to a first axial end face of the filter medium body and extends radially at most up to the clean side of the filter medium body. The ring filter element is employed in a filter device of a crankcase.

Crankcase ventilation device housing

A separating module for a ventilation device has a housing that surrounds a separating element designed to separate liquid particles from a gas flow. A line module and a ventilation device with such a separating module and such a line module are provided. The housing of the separating module is designed to be connected to the line module that has at least three geometrically parallel channels and the housing of the separating module has corresponding housing openings to be connected to the at least three channels. Several separating modules and several line modules can be combined to adapt the ventilation system as needed.

Separating module, line module, and ventilation device

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.

Separation element of liquid separator, separation medium, liquid separator, and method for producing separation element

An oil separator for separating entrained oil from a gas stream, the separator being arranged on a housing wall which divides a housing interior from a housing exterior. A support tube, which is arranged inside an outer casing and carries a filter element on its outer circumference through which gas can flow radially. The support tube is closed at its upper axial end face and communicates at its lower axial end face with the housing interior. An impingement separator is arranged in the vicinity of the lower axial end face of the support tube. The outer casing is closed at its bottom relative to the housing in a sealed manner.

Oil separator

A filter element (), especially suitable for separating entrained oil from an air stream, having a drainage device () including a drainage tube () which is connected to an upper end disk () of the filter element () by a connector () which may include preferably releasable clip hooks (). The resulting filter element with a drainage device is easy and economical to manufacture, and may have a modular construction in which the connector () and the drainage tube () are separate components so that the length of the drainage tube can be optimally matched to various filter dimensions.
