Industrial exhaust duct design.
Industrial duct systems are used for supply or exhaust are under positive or negative pressure of heavy or light duty construction convey clean and dirty airstreams constructed of metal plastic or fabric materials and assembled together with flanges clamps slip fit or welded.
Before discharging out the stack exhaust contamination can be reduced by filters collectors and scrubbers to maintain acceptable ai r quality.

Duct systems include straight lengths or sections of duct transitions elbows and bends enlargements or contractions hoods discharge stacks and hangers or supports.
The larger perimeter also means more air will come into contact wit the material and this adds friction to the system.
