Abstract:
An end member (3A) for a spiral separation membrane element includes: an inner annular portion (31); an outer annular portion (32) surrounding the inner annular portion (31) at a distance from the inner annular portion (31); a plurality of connecting portions (33) connecting the inner annular portion (31) and the outer annular portion (32); and a shield plate (34) disposed between at least one pair of the connecting portions (33) and forming an opening (41) between the shield plate (34) and the outer annular portion (32). According to this configuration, a radially outwardly spreading flow is formed by the shield plate (34), and therefore suspended solids in a feed liquid can be effectively directed to the peripheral region.
Abstract:
Crankcase ventilation filter assemblies, components thereof, features thereof, and methods of assembly and use are described. An example assembly is characterized in which the assembly includes a housing having an access cover and a base, and a filter cartridge is configured to sealingly engage both the access cover and the base, in preferred manners.
Abstract:
A filter module for fluids, comprising a pleated filtering membrane (6) the surface of which separates a pre-filtration volume, upstream of the filtering membrane (6), from a post-filtration volume, downstream of the filtering membrane (6), said pleated filtering membrane (6) presenting, on its surface, pleats bounded by contiguous crests (7), said filtering membrane comprising, on the pre-filtration volume side, a conveyor (10) for causing the filtrate to flow substantially between the pleats of the pleated filtering membrane (6).
Abstract:
An End Cap for an Assembly Used in the Preparation of Compressed Gas An end cap for attaching to one or more filter elements and respective filter bowls is disclosed. The end cap has a tubular body formed by extrusion and this body has a series of apertures formed therein. The apertures include an end aperture for attachment to a filter bowl and another end aperture for attachment to another filter bowl or to a sealing disc. The body also has a pair of sidewall apertures to act as inlet and outlet the filter assembly. The end cap also has a plastic insert for insertion into the body, the insert having a conduit portion for directing a stream of gas from the inlet to a filter element through one of the end apertures.

Abstract:
The invention relates to a filtering device for fluids, comprising a filter housing (I). At least one filtering element (9) which is in the form of a filter cartridge and which defines a longitudinal axis (11) can be received in said filter housing. The filter cartridge has an end cap (17) on at least one end, said end cap fanning an enclosure for the corresponding end edge of the filtering material (23, 35). The end cap can be fixed on an element receiving means (13), which interacts with the bottom part (5) of the filter housing (1), in order to fix the position of the filtering element (9) in the functional position thereof. The element receiving means forms a fluid path for the cleaned fluid exiting the filtering hollow chamber (19) of the filtering element (9). The filtering device is characterized in that the element receiving moms (13) contains a valve arrangement (55) which blocks the fluid path (35), and in that a control device (79, 83) which releases the valve arrangement (55) in the functional position is provided on the end cap (17) of the filtering element (9), said end cap being fixed on the element receiving means (13).
Abstract:
A fluid treatment filtering cartridge having a permeable filtering element and a permeable high-pressure resistant woven tubular fabric external cover formed by a radial weaving loom process that does not use adhesives, thermal bonding or ultrasonic welding techniques is disclosed. The external high-pressure resistant woven cover is secured to end caps of the filter cartridge by adhesives, thermal bonding or ultrasonic welding and surrounds the filter media to form the exterior surface of the filter cartridge and provide both circumferential and longitudinal strength to the filter cartridge in order for it to withstand internal pressures exceeding 250 psi.
Abstract:
A filter assembly and method of manufacturing the same is provided that uses an inductive heating system to secure a heat sensitive filter media to a plastic base. A metal disc is arranged between the plastic base and filter media with adhesive material arranged between the filter media and metal disc. The metal disc is excited using an inductive heating system to heat and care the adhesive material without damaging the filter media.
