Filtration media, media packs, and filtration elements are described, including fluted filtration media having offset flutes arranged to intermittently contact flutes on adjacent media, including angled and curved flutes. Pleated filtration media with alternating sealed pleat edges are also disclosed, including fluted media with alternating sealed flutes. A media pack can have a first sheet of media and a second sheet of media. The first sheet of media can have a first plurality flutes defining first flute valleys extending between a first face and a second face of the media pack. The second sheet of media can have a second plurality of flutes defining second flute peaks extending between the first face and the second face of the media pack. The first plurality of flutes can be non-parallel to the second plurality of flutes, and each first flute valley contacts one second flute peak at a discrete contact point.

An air cleaner assembly includes a precleaner assembly. In one aspect, the precleaner assembly incudes a bypass arrangement that is operated to bypass a portion of air around the precleaner assembly. The bypass arrangement can be operated by a controller based on at least one input signal corresponding to one or more of a vehicle speed, a vehicle engine speed, a vehicle engine load, an operator input, a vehicle location, an air pressure drop across a filter element, an air pressure drop across the precleaner assembly, an acoustic level, a vibration level, a change or cleaning frequency of the filter element, a total number of filter element changes, an identity of the filter element, an identity of the engine, an identity of the vehicle, an air flow rate through the precleaner assembly or through the filter element, and a weather condition parameter identified through data received locally or from a weather service.

A filtration media pack including a plurality of layers of filter media is disclosed. The media pack includes fluted sheets and a facing sheet, with a plurality of flutes extending between the fluted sheets and the facing sheets. In an embodiment, the fluted sheet includes a plurality of protrusions that contact the facing sheet.

Filtration media pack, filter elements, and air filtration media

Embodiments include an air filtration media element comprising a plurality of layers of fluted media, each layer comprising a facing sheet and a fluted sheet, the fluted sheet comprising a first plurality of flutes and a second plurality of flutes, the first and second plurality of flutes being arranged in a parallel flow configuration; wherein the first and second plurality of flutes exhibit regular repeating differences in flute shape, flute size, flute height, flute width, cross-flute area, or filter media.

Filter media, filter media packs, and filter elements

A filter element has a sheet of filter media having a first elongate edge and a second elongate edge. The sheet of filter media defines a plurality of pleats, a first set of pleat folds and a second set of pleat folds, where each of the plurality of pleats extend between the first set of pleat folds and the second set of pleat folds. The first set of pleat folds each extend from the first elongate edge to the second elongate edge, and the second set of pleat folds each extend from the first elongate edge to the second elongate edge. Each of the plurality of pleats defines a repeating wave pattern of flute peaks and flute valleys alternating from the first set of pleat folds to the second set of pleat folds. Each of the flute peaks and flute valleys extend from the first elongate edge to the second elongate edge.

Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly cannot be fully closed, even if a cartridge is nested therein, and appears to be sealed, unless that cartridge is a proper one for the system of concern. The effect is to prevent an inappropriate cartridge, that does not properly seal, from being inadvertently installed in the assembly.

A rodent electrocution assembly includes a housing that may be positioned on the ground thereby facilitating the housing to be aligned with a rodent tunnel. A pair of legs is provided and each of the legs is hingedly coupled to the housing. Each of the legs is urged to penetrate the ground thereby facilitating each of the legs to be positioned in the rodent tunnel. An electrifying unit is coupled to the housing. The electrifying unit is positioned in the rodent tunnel when the pair of legs is positioned in the rodent tunnel. The electrifying unit electrocutes a rodent when the rodent passes through the pair of legs.

The inventive concept is a device which is used to secure a sheath or stack of papers contained in an architectural sheet rack clamp. The device is essentially a three-tiered rectangular structure forming two parallel, length-wise channels within the spaces defined by the three tiers. One channel, situated as the upper clamp retaining channel, is structured so as to securely accommodate the typical sheet clamp used to store such materials as architectural drawings, maps, and other similar over-sized sheets. The second, or lower desk anchoring, channel of the device, contains two adjustable fastening means, enabling attachment of the lower desk anchoring channel to a desk, draftsman's stand, or table.

A faucet apparatus for mounting on sanitary fixtures such as sinks, washbasins or the like, provides simple and quick installation. The apparatus comprises a block portion inserted into a through hole made in the sanitary fixture and is adapted to protrude with a portion thereof above the sanitary fixture. A couple of passages extend through the block and are adapted to be connected below the sanitary fixture to water intake ducts, and above the sanitary fixture for supplying the faucet. The portion of the block portion protruding above the sanitary fixture is fully housed within the body of the faucet. The apparatus comprises also means for fixing the block portion to the sanitary fixture. The attachment means comprises a fixing member associated with the block and moved from an insertion position in which the fixing member is axially aligned with the hole in the sanitary fixture, and a blocking position in which the fixing member is able to engage the lower surface of the sanitary fixture in which the hole is made.
