Abstract: An apparatus for filtering contaminant-containing air has a base, an air filter positioned upon the base, a plate affixed over an end of the filter opposite the base, and a motor or fan suitable for drawing the contaminant-containing air through the inlet of the plate and into the interior volume of the air filter. The air filter has a generally annular cross-section. The air filter has an interior volume suitable for receiving the contaminant-containing air therein. A screen can be affixed over the exterior surface of the air filter. The air filter will have a structural integrity suitable for supporting the plate thereon.

Abstract: An apparatus for the extraction of gases has a flexible duct with an interior therein, a polymeric support extending in the interior of the flexible duct, a first anchor that secures an end of the polymeric support, a second anchor that secures an end of the flexible duct, and a duct connector. The first anchor secures the end of the polymeric support to the duct connector. The second anchor secures the end of the flexible duct to the duct connector. The polymeric support is elongated. The polymeric support has a taper and a thickness suitable for holding the flexible duct in a fixed position. The polymeric support is formed of a polycarbonate material.

Abstract: A particulate removal apparatus for use in soldering operations having a housing with an inlet opening formed therein and an interior cavity, a filter positioned within the housing for removing particles from air passing therethrough, an impeller positioned within the interior cavity of the housing, and a motor positioned within the interior cavity of the housing and positioned between the impeller and the filter. The impeller has backward inclined impeller blades. The impeller pulls air through the inlet opening and directs the air toward a wall of the interior cavity. The impeller blades generally surround the interior opening. The filter is a HEPA filter positioned within a framework within the housing. The HEPA filter is arranged in an accordion-style folded configuration within the framework.
