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.
Claims18
A particulate removal apparatus comprising:
- a housing having an inlet opening formed at a bottom thereof and having an interior cavity, said housing having a solid walls surrounding said interior cavity, said housing having an outlet formed at a top thereof;
- a filter means positioned in said housing adjacent said top of said housing, said filter means for removing particles from air passing therethrough, said filter means having an outlet for passing filtered air from said housing through said outlet of said housing;
- an impeller means positioned within said interior cavity of said housing, said impeller means having backward inclined impeller blades, said solid walls of said housing being generally parallel to an axis of rotation of said impeller means, said impeller means for pulling air through said inlet opening and for directing such air toward said walls, said impeller blades generally surrounding said inlet opening;
- and
- a motor means positioned within said interior cavity of said housing and positioned between said impeller means and said filter means, said motor means for rotating said impeller means.
A particulate removal apparatus comprising:
- a housing having an inlet opening formed at a bottom thereof and having an interior cavity;
- a filter means positioned in said housing adjacent said top of said housing said filter means for removing particles from air passing therethrough, said filter means having an outlet for passing filtered air through an outlet at a top of said housing;
- an impeller means positioned within said interior cavity of said housing, said impeller means having backward inclined impeller blades, said impeller means for pulling air through said inlet opening and for directing such air toward a wall of said interior cavity, said impeller blades generally surrounding said inlet opening, said impeller means having an open interior at a bottom and a closed top, said backward inclined impeller blades for directing air radially outwardly from said open interior toward said solid wall of said interior cavity;
- and
- a motor means positioned within said interior cavity of said housing and positioned between said impeller means and said filter means, said motor means for rotating said impeller means said motor means attached to and located above said closed top of said impeller means.
A particulate removal apparatus comprising:
- a housing having an inlet opening formed at a bottom thereof and having an interior cavity;
- a motorized backward inclined impeller means positioned within said interior cavity, said impeller means for pulling air through said inlet opening and directing the air toward a solid wall of said interior cavity;
- and
- a filter means positioned in said housing above said impeller means, said filter means for removing particles from air passing therethrough, said filter means comprising a HEPA filter positioned within a framework within said housing, said HEPA filter arranged in an accordion-style folded configuration within said framework, said filter means passing filtered air outwardly of a top of said housing, said housing having a horizontal support surface formed therein, said horizontal support surface forming a receptacle for said framework within said housing, said filter means further comprising:
- a filter seal interposed between a bottom surface of said framework and said horizontal support surface, said filter seal being formed of an elastomeric or foam material;
- and
- compressive contact means affixed to said housing and interactive with said framework, said compressive contact means for forcing said framework into air-tight compressive contact with said filter seal.
