Abstract
An air-channeling apparatus for channeling the flow of air into a dirty-air chamber of a dust collector. The air-channeling apparatus having a top baffle member secured with respect to the ceiling of the dust collector, the top baffle member positioned at the entrance port to the dirty-air chamber and inwardly converging toward the ceiling to define a first opening therebetween. A first angled baffle member is connected to and angled away from the top baffle member while a rear baffle member having a plurality of openings is attached to the ceiling of the dirty-air chamber inward of the first opening. Furthermore, a vertical baffle member is positioned in registry with a portion of the air entrance port and spaced from the ceiling. The vertical baffle member is secured with respect to the ceiling so as to define a second opening with respect to the side wall having the air entrance port. Finally, a second angled baffle member is spaced from and secured with respect to the ceiling. This second angled baffle member is spaced immediately inboard of the vertical baffle member between the vertical baffle member and the first angled member thereby defining a third opening between the ver…
