摘要:
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.

摘要:
Filter element or air filter in the configuration of a multiple bellows filter with an increased efficiency for use in internal combustion engines, wherein a folded filter bellows is arranged radially inwardly of another folded filter bellows and the inner folded filter bellows has a greater or deeper fold depth than the outer folded filter bellows.
摘要:
A filter material for an air filter may include a substrate layer on an inflow side and a fine-fibre layer on an outflow side relative to a flow direction. The filter material may include a connection region arranged between the substrate layer and the fine-fibre layer. The substrate layer, connection region and fine-fibre layer may include pores having an aggregate degressive pore size with respect to the flow direction. A combined thickness of the substrate layer, connection region and fine-fibre layer may be at least 0.35 mm. The substrate layer may include a cellulose material and have an impregnation of resin disposed along the inflow side. The resin may amount to approximately 22% by mass of the substrate layer.

Z-filters capable of cleaning particulate matter from airflow streams in dust collectors, including reverse flow, reverse air, and reverse pulse systems.
摘要:
A coreless and spirally wound non-woven filter element is provided. The filter element includes at least one band of base media having a selected porosity and an interlay having a different porosity within at least one band of base media. The presence of the interlay in the filter element can create additional surface area within the contiguous construction of a filter element for filtration. This interlay can also create the ability to change direction of flow and to increase the deposition of specifically sized contaminants.
摘要:
A filter includes a plurality of annular filter elements arranged in axially staggered relation. An axial flow path includes a plurality of flow path segments, some being filtered by a respective filter element, and others bypassing a respective filter element. Various combinations are provided.
摘要:
A filter device has a compact filter made of a filter material that is wound spirally. A star filter that is made of a filter material that has folds arranged in a star shape surrounds the compact filter. The filter device has a cylindrical shape. A fluid to be filtered passes the compact filter in an axial direction and the star filter in a radial direction. The filter device is exchangeable and is mounted in a filter housing such that the compact filter and the star filter have a common raw side and a common clean side that are separated from each other.
