ABSTRACT:
A ventilated work chamber, e.g., a paint booth, large enough to allow a worker to move about inside is improved by confining the zone (or path) of the 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, as the worker changes his location.
