Abstract
An apparatus for filtering airborne contaminates that has a frame member and a collection duct attached thereto. A duct assembly is slidably supported on the frame member and selectively movable along a linear path between a first position adjacent the frame member and collection duct and a second position displaced from the frame member. A fan for inducing airflow into the collection duct and duct assembly may be attached to the duct assembly for travel therewith or attached to the frame and the duct assembly when the duct assembly is in the first position. The duct assembly may be selectively movable between the first and second positions along a linear path relative to the frame member by a slidable support attached between the frame member and duct assembly.
