As the unique manufacturer of germproof air duct in china, we are specializing in the manufacture and export of kinds of Germproof air duct, glass fabric air channel, ventilation pipe, compound duct and so on, Our “Aning” brand Anti-germs duct which are registered got an excellent reputation in the heating and ventilation field. Aning air duct board is one of the most advanced air duct materials utilized worldwide. The Aning ventilation system, a thick flat fibrous glass duct board, can directly replace traditional sheet metal systems with applied insulation. The insulated board and pre-molded “double-density” slip joints provide ease of fabrication and installation, reducing labor costs and improving construction schedules. Aning air duct is an environment friendly product providing excellent indoor environmental air quality. The Board is made of strong, resilient glass fibers bonded with thermosetting resin, this process guarantees a much enhanced product life; the exterior surface of the board is made of reinforced aluminum foil, which has excellent thermal properties; The patented black interior coating is bonded with acrylic acid polymers, which encapsulates the glass fibers and prohibits the growth of bacteria and microorganisms on the interior surface. Through these Technologies we achieve minimum fiber exposure towards the air-stream, reduced moisture absorption and microbe growth, exceptional durability and superior acoustical qualities. Bring it can be widely applied to air delivery systems of central air conditioning units in hotels, apartments, hospitals, office buildings, factory, super market and other deluxe high-rise buildings. Aning Air Duct Board is available in 25mm, and 38mm thickness. Standard board size is 1219*3048mm and 1219*2438 mm. Aning Air Duct Boards can be joined to build ducts of any size or length.
