Abstract: A hollow articulating structure includes a plurality of pipes interconnected with a plurality of knuckle assemblies. The hollow articulating structure may be connected to a vacuum source to allow a user to move the articulating structure to position an end of the articulating structure in a desired location to move dust and particles through the hollow articulating structure to the vacuum source. Each knuckle assembly includes a first knuckle member and a second knuckle member that are rotationally movable with each other to allow the articulating structure to be adjusted and moved.

Abstract: Dust separation devices are disclosed to enable separating and collecting dust particles. A parabolic cyclone chamber is disclosed. The parabolic cyclone chamber has a bottom having an opening, an upper surface, a curved sidewall connecting the bottom to the upper surface, an entry path in a top portion of the cyclone chamber, an exit path extending through the upper surface, and a diverter wall sloping downward from the upper surface of the cyclone chamber toward the entry path.

Abstract: An air scrubber having an outer shell, the outer shell having a first sidewall with a first aperture, a second sidewall with a second aperture, a third sidewall with a third aperture, and a fourth sidewall with a fourth aperture. Each of the apertures are configured to engage a filter. The air scrubber includes a fan configured to move air inward through each of the apertures and through the associated filters to filter contaminants from the air.

Abstract: An adapter having a body, wherein the body includes a first portion having proximal end, a distal end, an inner surface and an outer surface, and a second portion having a proximal end, a distal end, an inner surface and an outer surface, wherein the first portion of the body is adapted for releasable connection with an input of a wet/dry vacuum cleaner, a shop-vac, and/or a dust extractor, and wherein the second portion of the body is adapted for releasable connection with a plurality of hoses.

Abstract: Monolithic dust separation devices are disclosed to enable separating and collecting dust particles. The devices include a vacuum port and a cyclone chamber that are connected by a tube between the vacuum port and an upper end of the cyclone chamber. On the cyclone chamber there is an input port for connecting to a flexible hose for ingesting the dust particles. The devices also include a dust receptacle having a top upper surface and a port cover on a port formed in the upper surface for emptying the receptacle of collected dust particles and a lower portion of the dust receptacle that is integrally formed into the upper surface of the dust receptacle. The top upper surface slants downward from the cyclone chamber to the port cover.
