カタログの1ページ目を開くFume Hood Ducting and Exhaust System Ductwork connected to fume hoods may be arranged in a variety of patterns depending on requirements. Generally, the best exhaust system involves the shortest duct length and the fewest elbows. Duct size, length, and number of elbows affect static pressure loss and blower efficiency. Ideally, each fume hood should have its own ducting and blower to maximize hood flexibility and reduce danger of backdraft from other hoods. Common or manifold ductwork designs can be used, provided duct and blower have been sized properly. In these designs, individual hood...
