Ventilation ductwork can be divided according to its shape, namely, circular, rectangular and oval (a compromise between rectangular and round ventilation ducts).
Spiral Ducts and fittings along with Rectangular Ducts Series will complete your piping system. Spiral pipe is commonly used in dust collection as well as other applications such as industrial ventilation, spray booth stacking, welding booths, paper trim, pharmaceutical clean rooms, etc.
It can be also distinguished according to the material from which it’s made, e.g. rigid spiral pipe is usually made of galvanized steel sheet; flexible ducts often made of aluminium, polyester foil, etc. By far the most popular ductwork types used for both residential and industrial ventilation systems are rigid spiral ducting and Rectangular Duct.
