FIELD: ventilation and air conditioning.
SUBSTANCE: invention relates to ventilation and air conditioning equipment and can be used in supply and exhaust ventilation systems. In compliance with this invention, proposed is air pipeline with simple design and low material consumption at provision of high rigidity of structure and low aerodynamic resistance to air flow. Disclosed is ventilation duct (1) with three bulged outward curvilinear walls (2) by type of stiffness elements and a cross section in form of triangle Relo (3). Inside air duct there are spring, split, spacer rings (4).
EFFECT: described is an air duct.
