Air ducts for ventilation of grain in warehouses are made of galvanized steel with fine perforations over the entire area of the air duct, preventing grain from entering inside, but ensuring unhindered passage of air in the intergranular space.
The design of the air ducts allows to withstand the height of the grain embankment up to 6m.
NPP ZIPO manufactures air ducts for grain ventilation in two types of forms:
- round air ducts with a diameter of 250 mm, 315 mm, 355 mm, 400 mm, 450 mm, 500 mm.
- semicircular air ducts with a radius of 250 mm, 315 mm, 355 mm, 400 mm, 450 mm, 500 mm.
