Abstract:
A non-fouling, bypass filter is disclosed. The filter is formed of a tapered structure having particulate material filtering properties. The tapered structure has an open base and a closed top, with its exterior surface being exposed to a gas/fluid stream to be filtered. A gas/fluid stream generating device generates a gas/fluid stream that is drawn into the tapered structure's interior and that is filtered due to the particulate material filtering properties of the tapered structure. The external profile of the conically shaped structure is adapted to cause a plurality of gas/fluid streams from the ambient gas/fluid to flow against the exterior surface of the tapered structure to prevent the building up of particulate material on the exterior surface.
Abstract:
The present invention relates to a method and device for the purpose of filtering particulate laden air exiting a rooftop from a commercial kitchen or other high particulate laden air exhaust. By positioning a filter at a distance from the air exhaust exit in such a manner that the air flow is reflected off the filter a substantial portion of the particulate matter is filtered out of the air without substantially obstructing the flow from the exhaust preventing problems that might be caused from creating back flow in an exhaust system.
Abstract:
The invention relates to a vacuum suction and cleaning apparatus comprising a nozzle (38), ventilation means (40), a clean water tank (20), an air-water separator (50), a recovery tank (4) for soiled liquid and/or dirt, a handle (5) for manipulation with one hand, a heating means (19) using a ceramic for electrical and thermal insulation.It is wherein the separator (50) comprises a brush (2) driven in rotation, that prolongs the ventilation means (40), rotating with a turbine (11) or nozzle (51) serving as support, and that the apparatus (100) comprises an air evacuation hose (6) incorporated in the handle (5) prolonging a by-pass, and that the recovery tank (4) is located under the separator (50).
Abstract:
An air filter arrangement, an air cleaner assembly including the air filter arrangement and methods of assembly and use are described. An air filter arrangement comprising a serviceable filter cartridge is described. The typical cartridge includes a recessed first flow face and an opposite outwardly projecting second flow face, with a central apex. Features of the cartridge, and an air cleaner for installation into the cartridge, are described.
Abstract:
A filter element may be provided. The filter element may include a fitting; and a filtering member coupled to the fitting, the filtering member may include a plurality of flutes defined in an outer surface of the filtering member.
Abstract:
The disclosure concern air cleaners. Preferred air cleaners are shown which include a housing and a removable and replacement primary filter cartridge. Optional and advantageous features are shown. The preferred primary filter cartridge is conical in shape. A preferred optional safety or secondary filter cartridge is shown. Preferred methods of assembly and use are provided.
Abstract:
A vacuum cleaner having a housing, a suction fan, a dustcup, a cover and an inlet into the dustcup. The dustcup is removably secured to the housing, and includes a cup end wall, a sidewall extending from the cup end wall, and an open end opposite the cup end wall. The cover can be connected to the open end of the dustcup, and includes an air outlet in fluid communication with the suction fan, and a filter covering the air outlet and extending from the cover towards the cup end wall. The cup end wall includes a barrier positioned to be contacted by air flowing through the dustcup to thereby separate dirt particles from the air.
Abstract:
A filtration apparatus includes at least three filter elements for filtering fluid, and a frame having a pyramidal frustum configuration that has at least three sides. The frame includes a frame structure for supporting the filter elements at the sides such that the filtration apparatus has a pyramidal frustum configuration. The filtration apparatus may be part of a filtration assembly. The filtration apparatus may be utilized within an associated method.
Abstract:
The disclosure concern air cleaners. Preferred air cleaners are shown which include a housing and a removable and replacement primary filter cartridge. Optional and advantageous features are shown. An optional mechanical interlock, operated with a non-threaded, movement of the cartridge, is provided between the primary filter cartridge and the housing. The preferred primary filter cartridge is conical in shape. A preferred optional safety or secondary filter cartridge is shown. Preferred methods of assembly and use are provided.
Abstract:
