| 20090188223 | AIR TREATMENT SYSTEM - An air treatment system includes features for maximizing efficiency and effectiveness. In one embodiment, a sensor air passage utilizes a low pressure region created by the blower to draw air through the passage. In another embodiment, a filter frame includes a plurality of connectors formed integrally with the filter frame. In another embodiment, a screen is positioned adjacent to the blower intake. The screen includes a plurality of angled strands oriented in a particular direction. In another embodiment, a remote control holder is formed integrally with the housing. In another embodiment, a gasket is positioned between the blower and the housing, forming a seal between the blower and the housing. | 07-30-2009 |
| 20100050581 | FOLDING FRAME FILTER - A foldable filter having a flexible filter media, a frame surrounding and supporting the filter media, the frame formed of rod members, at least two of which are flexible, each rod member extending between and connecting two corner regions, with the filter media being secured along its edges to the rod members. The filter may be folded by grasping two opposite rod members, rotating the two opposite rod members end over end oppositely relative to one another about a point generally midway along a length of the rod members to effect a relative 180 degree rotation between the two rod members, twisting the filter media, and folding the filter media in half by bringing the two rod members to lie on top of one another. | 03-04-2010 |
| 20110265438 | TURBINE ENGINE WITH ENHANCED FLUID FLOW STRAINER SYSTEM - A fuel delivery system for a turbine engine includes a fluid supply conduit. The conduit has an inner peripheral surface that defines a flow supply passage. A fuel strainer is received in the conduit. The strainer has a hollow, generally frusto-conical body with an outer peripheral surface. The strainer has a longitudinal axis. A plurality of holes extends through the body substantially radially to the longitudinal axis. The holes have an associated effective flow area. The outer peripheral surface of the body is radially spaced from the inner peripheral surface of the conduit along the length of the strainer such that a flow area is defined between the outer peripheral surface of the strainer body and the inner peripheral surface of the fluid supply conduit. The flow area is equal to or greater than the effective flow area of the strainer holes along the length of the strainer. | 11-03-2011 |
| 20130291503 | FILTER DEVICE - A filter device for gases may include a housing having a first housing and a second housing configured to axially abut each other in a flange regione. A plate-shaped filter element may have a circumferential seal arranged in the flange region. The first housing part may have two mutually opposite radial bearing faces in a flange region and the seal may have two radial sealing faces facing away from each other and each sealing face may bear flat against the respective bearing face. | 11-07-2013 |
| 20140144115 | COLLAPSIBLE EXTENDED SURFACE FILTER AND AIR CLEANER SYSTEM USING COLLAPSIBLE EXTENDED SURFACE FILTER - A collapsible air cleaner filter is provided. The filter includes a pleated media filter having a first end, a second end, and a filter media extending between the first and second ends, wherein the filter media includes a first plurality of flexible end portions and a second plurality of flexible end portions, the first and second plurality of flexible end portions are separated by a plurality of pleats, and the filter media extends a first length between the first and second plurality of flexible end portions, and an end member coupled to the first end of the pleated media filter, the end member extending a second length parallel to the first length, the first length being greater than the second length. | 05-29-2014 |
| 20150033689 | Filter System for Filtering Fluids - A filter system for filtering fluids has a housing, an inlet, and an outlet. A filter element is arranged inside the housing. A cover closes the housing and provides access to the filter element inside the housing. A securing device prevents the housing from being closed by the cover when the filter element is missing. The filter element has at least one filter element guide path section. The housing or the cover has a rim area with at least one rim guide path section. The filter element guide path section and the rim guide path section supplement one another to a guide path. The securing device comprises at least one securing element arranged on the cover or the housing. The securing element is guided on the guide path when a closing movement is carried out for closing the housing by the cover. | 02-05-2015 |
| 20160101380 | Filter Housing, Hollow Filter Element and Filter - A filter housing of a filter for air, water, fuel, oil or urea-water solution of an internal combustion engine, including: an inlet for fluid to be purified; and | 04-14-2016 |
