Ventilation duct are generally erected indoors. In order to reduce the indoor height of the net layer (usually set in the ceiling), the general design of high to small, wide to large rectangular ventilation pipe, such as set aside in the outdoor space requirements , It is appropriate to use a circular to reduce the ventilation resistance and the amount of material, while the rectangular tube processing easy, this is also a reason.

Ventilation rectangular duct is industrial and civil buildings for the ventilation and air conditioning works with metal or composite pipes, which are a municipal infrastructure for air circulation and reducing the concentration of harmful gases. Ventilation ducts in the production and installation of ducts used in the plate, profiles and other major finished materials, should be consistent with the design and related products, the current national standards, and application of factory inspection certificate, the material approach should be based on the current national standards for acceptance.

For the more complex civil buildings, in the design phase, the various types of work (HVAC, water supply and drainage, power supply lighting and construction) should first negotiate a good space separation, set the elevation of each pipeline range. Under normal circumstances shall not be out of their own limits. In case of individual pipe section to cross the border should consult with other projects.
