ABSTRACT:
A ventilated enclosure, for example a paint-spraying booth, is divided into two or more zones by one or more isolating curtains of rapidly-flowing air. One longitudinal curtain is used on each side of the object to be treated in the enclosure, to provide a central longitudinal zone for the surface treatment process and two side zones for the workmen. The two curtains converge downwardly toward each other so that the ventilating air flowing downwardly between the curtains exits from the central zone largely by way of the space between said objects. Transverse curtains and/or additional longitudinal curtains may also be used with special advantages, particularly when the speeds and positions of the curtains are specially selected.
