The present invention discloses a rectangular shaped filter and coalescer elements and a vessel that houses a plurality of such rectangular shaped elements. Greater filtration or separation efficiency is provided due to increased number and alignment of rectangular shaped filter elements in the vessel. The rectangular shaped filter elements are also easy to replace.

Systems are provided for an oil system including a filter with a large surface area. In one example, a system may include an oil filter with a prismatic shape. This shape may include a filter surface area greater than an inlet area of an oil port and the filter surface area may also be located a distance away from the oil port.

The present invention relates to a filter panel (1) intended for a drum filter (2), said filter panel (1) having multiple filter holes (3) wherein each filter hole (3) has a length L and a width W, wherein at least a substantial amount of the filter holes (3) has a length L which is at least 1.5 times the width W, wherein the filter panel (1) has a free surface area which is higher than 81%, preferably at least 83%, more preferably at least 85%, on a side of the filter panel (1) intended to be in contact with a filter cloth of the drum filter (2).

A high efficiency air filter assembly (100) for high temperature applications comprising: a filter core (102) including a unitary sheet of air-permeable filter media folded in accordion fashion to form a plurality of side-by-side pleats with zig-zag edges on two opposite sides and flat panels on the other two sides, and a spacer member between opposing walls of successive pleats, a box-like metal frame (108) enclosing said filter core on four sides in air tight engagement to define an air flow opening extending between upstream and downstream sides of said assembly, wherein the zig-zag edges of the unitary sheet of air-permeable filter media are sealingly embedded in a solid inorganic sealant composition (118) in the frame, and wherein the unitary sheet of air-permeable filter media preferably consists of a binder-free glass or mineral fiber filter media. Use of the high efficiency air filter assembly in high temperature applications wherein the filter assembly is repeatedly or continuously heated to a temperature in the range of 200-500? C.

An air-dirt separator adapted to reduce entrained air and separate debris from fluid moving through the air-dirt separator is described in the present disclosure. The air-dirt separator includes a housing and coalescing baffles mounted in the housing.

Systems and methods are disclosed that capture video in mobile applications and automatically archive the captured videos using short-range communications with a network storage device. In various embodiments, the archival is triggered by proximity to the wireless network device. In various embodiments, other triggers, such as those provided by location-based services are used to initiate archival via a wireless protocol.

A water inlet protection system is provided. The system may an adjustable frame defining an interior cavity, the adjustable frame including a plurality of rigid base members, a plurality of slidable corner members, a plurality of nut-and-bolt fasteners, and one or more tabs extending from one or more of the corner members. Each of the slidable corner members includes one or more slots, and each of the nut-and-bolt fasteners includes a bolt that extends through one of the one or more slots and one of the rigid base members. When the respective bolt is loosened, the respective slidable corner member is slidable along the respective slot atop the respective rigid base member, thereby altering a boundary of the interior cavity. When the respective bolt is tightened, the respective slidable corner member is fixed in place atop the respective rigid base member, thereby fixing the boundary of the interior cavity.

A filter element including a first filter media pack with an inlet face and an outlet face and a second filter media pack with an inlet face and an outlet face. The second filter media pack is formed separately from the first filter media pack and is coupled to the first filter media pack such that the respective inlet faces and outlet faces of the first and second media packs do not overlap. The first filter media pack and the second filter media pack each include a corresponding filter media pack characteristic, and the filter media pack characteristic of the first filter media pack is different from the corresponding filter media pack characteristic of the second filter media pack. Exemplary filter media pack characteristics include the length, width, height, shape, media density, layer spacing, pleat bend angle, pleat density, and material composition of the first and second filter media packs.

A draw latch retainer is used to secure a filter cartridge to a filter head. A cam actuated retainer extends from the head to engage a keeper in the top of the cartridge. Rotation of the cam draws the retainer and cartridge axially toward the head into an installed position. The retainer extends through an aperture in the upper portion of the cartridge to apply a retention force against the bottom side of the keeper. The keeper and upper portion of the cartridge supporting the keeper are configured to transmit the retaining force laterally across the top of the cartridge. A pair of axial conduits project from the cartridge and mount O-ring seals for implementing an axial sealing interface with passages in the head.

A filter assembly for filtering diesel fuel used by a diesel engine includes a housing that defines a housing opening, an unfiltered fuel inlet and a filtered fuel outlet. A panel is matable to the housing for sealably enclosing the opening for forming a housing chamber. A panel encloses the opening and defines an inner surface. A filter element formed from a peripheral wall includes filter media defining an unfiltered side and a filtered side of said filter element. The peripheral wall is sealably affixed to the inner surface enclosing the unfiltered side of the filter element from the housing chamber defining an unfiltered chamber. A permeable barrier is affixed to the peripheral wall defining a filtered chamber with the filtered side of said filter element receiving filtered fuel through the filter media. The housing chamber receives filtered fuel through though the permeable barrier.
