Ducting
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. Duct systems include straight lengths or sections of duct, transitions, elbows, and bends, enlargements or contractions, hoods, discharge stacks, and hangers or supports.
Duct design if performed correctly allows conveying of all air and particulate without deposition of materials, at a design carrying velocity with minimal pressure loss and at reduced fan horsepower.
