摘要:
A compact filter has a compact filter element for exchangeable use in a filter housing and the compact filter element has a filter body of a web-shaped filter medium. The web-shaped filter medium has at least one flat filter medium web and one corrugated filter medium web that are placed onto each other and at least partially connected to each other by ultrasonic welding. At least one of the flat and corrugated filter medium webs is a composite filter medium web of at least two components, wherein at least one component is a synthetic material and one component is a non-synthetic material. The non-synthetic material is a plant-derived material and forms a support of the composite filter medium web and the synthetic material is a synthetic layer applied on the support.

A filter element for cleaning a fluid having a pleated filter medium designed for radial flow, to the outside of which a circumferential reinforcing thread is applied. The outside of the filter medium is divided into two axial sections, to which the reinforcing thread is applied in a plurality of circumferential thread windings, such that the axial distance between directly adjacent thread windings differs in the two sections.
摘要:
An air filter for internal combustion engines and interiors of motor vehicles has a filter insert in the form of a bellows of filter material folded in a zigzag shape by a first folding, wherein the bellows has a plurality of neighboring pockets extending in a longitudinal direction of the bellows, wherein between the pockets first folds are formed at ridges between the pockets. A seal is connected to the bellows. The folded filter material has a second folding in a direction transverse to the longitudinal direction and second folds are formed by the second folding that extend substantially transversely to the longitudinal direction. End faces extending transversely to the longitudinal direction are formed by cutting the bellows to a desired length. The seal extends across the end faces and longitudinal sides of the bellows.
摘要:
A filter device for filtering air in internal combustion engines equipped with a filter that can be inserted into a filter housing and has a flame-retardant effect. The filter comprises a main filter element and an upstream filter fleece whereby the flame-retardant effect is achieved by the fleece prefilter.
摘要:
The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. The pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the pipe interior.
摘要:
The invention relates to a filter arrangement (1) for filtering a fluid, e.g. combustion air for a combustion engine. Said filter arrangement has several tubular sections or segments (2, 3). At least part of a wall (4) of at least one tubular section (2) comprises a filter material (4B). At least one tubular section (3) is designed in a bendable manner like a folding joint (5A).
