A filter for filtering particulates from a fluid stream includes a filter element, a first end cap, a second end cap, and a wrap. The end caps are respectively secured to the ends of the filter element to form a fluid tight seal therebetween. At least one of the end caps defines an opening therethrough in fluid communication with the interior passage of the filter element. The wrap is in the form of a strip secured to at least the filter element. The wrap comprises a conductive layer comprising an electrically-conductive material. The wrap is wrapped around the filter element such that at least forty percent of the outer surface area is covered by the conductive layer.

A filter for removing particulate matter from a contaminated fluid. The filter includes a housing with an inlet for receiving the contaminated fluid and an outlet for releasing the filtered fluid. A sieve is mounted within the housing and includes perforations to allow both the passage of the contaminated fluid and collection of particulate matter from the filtered fluid. The filter further includes a turbine for rotating the sieve about a central axis and a spray bar mounted within the sieve. The rotation and spray removes particulate matter from the sieve for disposal.

A filter assembly includes: a filter cartridge having filter media and a first end cap holding an axially disposed seal member, an end arrangement sized to engage against the filter cartridge and form a seal with the seal member, and an anti-rotation arrangement constructed and arranged to prevent the filter cartridge and cover arrangement from rotation relative to each other.

A filter assembly includes: a filter element having filter media; an end arrangement removably positionable over the filter element; a first abutment member and a second abutment member capable of abutting when the assembly is in a first condition and prevented from abutting when the assembly is in a second condition; and a transition arrangement to enable transition of the assembly between the first condition and second condition.

Corrugated screen filters and related method of fabrication whereby an available filter surface is increased so as to allow an increase a flow capacity of the corrugated screen filter. The corrugated screen filter can comprise a plurality of rods forming a series of alternate and angular ridges and grooves on a surface of the filter screen. The filter screen can be configured to have longitudinal corrugations only on an exterior surface of the filter screen or alternatively, the filter screen can be configured to have longitudinal corrugations only on an interior surface of the filter screen. The alternate angular ridges and grooves can form corrugations in a variety of configurations including, but not limited to, a sinusoidal wave structure, a triangular wave structure, a rectangular wave structure, a trapezoidal wave structure, or the like.

A tank for storing oil includes a suction strainer with first and second filtration portions. The first filtration portion has a substantially cylindrical shape and formed by bending a thin plate into a pleated shape. The second filtration portion is provided on the outer side of the first filtration portion. The second filtration portion has a substantially cylindrical shape and is formed of a material having a plurality of spaces formed in a surface and interior of the material.

The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. There are restrictions on the allowable pressure drop across the strainer and the space available for installing this equipment. The finned strainer of the present invention addresses these issues while maximizing the quantity of debris filtered from the water.

An industrial filtering device is provided, including a shell body, having a receiving space, an outlet portion and an inlet portion, the outlet portion and the inlet portion respectively communicating with the receiving space, the inlet portion and the outlet portion defining a flow passage therebetween; a filter, including a PP filter material, the filter received in the receiving space and laterally arranged in the flow passage, the filter being pre-wetted and having an outer diameter which is between 75 mm to 88 mm.

A filter system (200) includes a housing (210) in which a replaceable filter element (100) is arranged between a pre-filtration side (202) and a post-filtration side (204). The filter element (100) has an element-fixed central tube (150), wherein a closure element (10) is provided on a housing side, the closure element (10) opening a post-filtration-side fluid outlet (250) when the filter element (100) has been inserted, and blocking the post-filtration-side fluid outlet (250) when the filter element (100) has been removed. The filter element (100) has an actuating element (160) for the closure element (10).
