ABSTRACT:
An air handling system comprising a track having a lower extent for supporting an object to be conveyed by the flow of pressurized air and an upper extent having a plenum chamber for receiving pressurized air and for directing it in contact with the object to be conveyed for effecting movement of the object. The track also has air-directing louvers between the upper and lower extents and an aperture in the upper extent. An impeller is mounted adjacent to the aperture of the upper extent of the track. A tapering input duct with an inlet end and a circular outlet end are mounted adjacent to the impeller with a circular screen in the outlet of the duct adjacent to the impeller. The screen has a centrally disposed hole. A baffle is mounted adjacent to the screen. The baffle includes a plurality of pie-shaped segments each with an arcuate outer edge overlying the periphery of the screen and with V-shaped interior edges with a hole. The segments are similarly configured. The baffle also includes a threaded rod extending through the holes of the segment and screen with an associated locking nut to hold the segment in a preselected orientation with respect to the screen between a fully opened upper orientation when the segments overlie each other and a fully closed orientation of about 0 degrees where the edges of all the segments overlie each other.
