Abstract:
A modular apparatus for collecting dust and fumes, said apparatus comprising:a filter section for removing dust and fumes from a flow of air, said filter section comprising: a collector barrel having a generally cylindrical interior and mounted so that a cylindrical axis thereof is aligned in a substantially vertical direction; a vertically elongate filter cartridge having a hollow interior and a generally cylindrical exterior which extends substantially coaxially within said collector barrel so as to define an annular flow space between said filter element and said collector barrel; an upwardly directed intake opening located centrally in an upper end of said collector barrel for receiving said flow of air in a downward direction generally coaxial with said barrel and said filter cartridge; and a plurality of stationary, angled, vanes mounted at an upper end of said collector barrel and extending radially from said central intake opening, for receiving said flow of air in a generally coaxial direction from said intake opening and redirecting said flow of air on a generally downward and outward cyclonic flow path through said annular flow space so that comparatively heavy material in said flow of air are forced outwardly towards an interior of said collector barrel and away from said exterior of said filter cartridge; a blower section mounted to a lower end of said filter section for drawing flow of air from within said hollow interior of said filter cartridge; a silencer section mounted to said blower section for receiving said flow of air from said blower section so as to reduce noise emissions from said apparatus; and a means for mounting said central intake opening of said filter section to ductwork for conducting said flow of air from a work area.
