Air treatment apparatus

A fluid treatment apparatus for conditioning a flow stream of fluid, said fluid treatment apparatus comprising:

• a housing enclosure disposed within said flow stream and communicating therewith, said housing enclosure arranged into two, spaced-apart flow chambers which define a clearance region therebetween, said housing enclosure being further adapted to split any entering flow stream into two flow branches, a different flow branch passing through each flow chamber;
• a series of drive rollers disposed in each flow chamber, drive rollers in one flow chamber being aligned with drive rollers in the other flow chamber;
• a plurality of common drive shafts extending through said clearance region and into each flow chamber and being adapted to support, with one at each end, a corresponding aligned pair of drive rollers;
• a continuous belt of filtering material disposed within each flow chamber and arranged across the corresponding flow branch via the corresponding drive rollers;
• and
• drive means disposed within said clearance region and cooperatively coupled to said plurality of common drive shafts for moving each continuous belt of filtering material.

A fluid treatment apparatus for removing particulate matter from a flow stream, said fluid treatment apparatus comprising:

• a housing enclosure having a single inlet plenum, a single outlet plenum and two, spaced-apart flow chambers positioned therebetween and in flow communication with said two plenums and further defining a clearance region between said two flow chambers, said housing enclosure being adapted to split any incoming flow into two flow branches, a different one of said flow branches extending through each flow chamber from inlet plenum to outlet plenum;
• a separate filtering subsystem disposed within each flow chamber and comprising:
• (a) a series of spaced-apart drive rollers;
• (b) a continuous belt of filtering material disposed around said series of spaced-apart drive rollers;
• and
• (c) a plurality of drive shafts spanning said clearance region and cooperatively coupled at one end to drive rollers of one flow chamber and at the opposite end to aligned drive rollers of the other flow chamber;
• and
• drive means disposed between said two, spaced-apart flow chambers and cooperatively coupled to said plurality of drive shafts and operable for moving each continuous belt of filtering material.
