AERODUCT®, Flexible Aluminium Air Ducts.

AERODUCT® is a fully flexible, compressible and extendable air duct. Made of 2 ply multi-layered Aluminium Polyester Foil bonded together by quality adhesive and reinforced with high carbon corrosion-proof spring ware. Designed with only 1" spacing (25 mm) between the spring wires, Aeroduct is strong, durable and will not go out of shape even when fully extended. Aeroduct is nonflammable, more efficient and more popular when compared with other flexible ducting system especially low cost single ply flexible air ducts.

CHARACTERISTICS

Able to withstand high air pressure Strong and Durable with 2 ply double facing aluminium foil No problem of air leakage Aeroduct offers smooth Inner core which provides low friction loss Low operating cost Compressible and extendable by more than 10 times its original size. No problems of shrinking when fully extended. Non-flammable.

SIZE AVAILABLE

Available in various I.D. ranging from 100 mm to 600 mm (4" to 24") Supplied in Standard length of 10 metres each Packed individually in caton sizes of : 75 cm long for bare Aeroduct and 175 cm long for Aeroduct insulated with fiberglass insulation.

APPLICATIONS

Ideal for all air conditioning/ventilating systems and any other industrial or residential applications including hospital, hotel, commercial and office buildings. Very flexible and can be connected to whatever position required. Economical, quick and easy to install even in complicated unworkable areas where other ducts cannot reach. Available bare or preinsulated with fiberglass of thickness 25 mm (1"), 38 mm, (1 1/2") or 50 mm (2") x 16 kg/cubic m or 24 kg/cubic m.
