Title Increasing the effectiveness of exhaust hoods
Original title Povyšenie ėffektivnosti vytjažnyh zontov [in Russian]
Bibliographic information Jan. 1984, No.1, p.46-48. Illus. 4 ref.
Abstract The effectiveness of hoods for local exhaust around large and/or hot pieces of industrial equipment can be increased by placing conical or pyramidal inserts in the hoods. Contaminated air is thus exhausted through ring-shaped slots, and air speeds in the vicinity of the modified hoods are increased. Installation of modified hoods over carburettor-casting machines reduced workplace air pollution by 4-6 fold.
