Abstract:
1. A vacuum filter assembly for filtering particulates from air during a scrap metal cutting process, said vacuum filter assembly comprising: a container defining an enclosed air chamber between an air inlet and an exhaust outlet, said container having a front inlet side, a rear side, a top wall extending between said front and rear sides, a bottom wall extending between said front and rear sides for supporting said container, and spaced apart side support walls extending between said front and rear sides; a primary air flow deflector positioned within said container for deflecting and directing the flow of air along a predetermined path within said air chamber from said air inlet to said exhaust outlet, said primary air flow deflector extending between a lower end fixed to said bottom wall and an upper distal end spaced below said top wall defining said air inlet therebetween; a secondary air flow deflector extending between an upper end fixed to said top wall and a lower distal end spaced above said bottom wall and spaced between said primary air flow deflector and said rear side for redirecting the air flow along said predetermined path through said air chamber between said air inlet and exhaust outlet; at least one fan operatively coupled to said container and in fluid communication with said air chamber for creating a vacuum suctioning air through said air chamber between said air inlet and said exhaust outlet; and a series of spaced apart and parallel filters positioned within said air chamber along said predetermined path between said secondary air flow deflector and said rear side adjacent said exhaust outlet for filtering particulates from the air prior to the air exiting the exhaust outlet to the atmosphere.
