The Mobile Zone device represents advanced waste reduction technology rather than a pollution management technology. The innovative concept is applicable to ventilated work chambers where the ventilation is provided from the removal of noxious fumes and/or particles and the work chamber is provided for the benefit of worker and product. The most common ventilated work chambers in use are spray booths for painting. The next most common ventilated work chambers are booths for the lay up and spraying of fiberglass or composite products. The ventilated work chamber is improved by confining a zone (or path) of fresh ventilating air to just a portion of the cross section of the chamber, and providing means for shifting the location of the ventilating air zone from one place to another in the chamber, to serve the worker as he change his location. This greatly reduces the quantity of VOC contaminated air generated by the spray booth.
