ABSTRACT:
A hood assembly for at least partially defining an enclosure in which two or more non-parallel rapidly moving air streams cooperate to entrain minute air borne particles in the enclosure to recover the latter and prevent the escape of the particles through an opening in the forward part of the enclosure. The air defining the air streams may in whole or in part be discharged to the ambient atmosphere substantially free of entrained air borne particles, or the air may be sequentially recycled through the enclosure. The hood assembly is particularly adapted for paint spray booths, but is equally useful and effective, when the air borne particles constitute smoke or fumes.
