GM-II Wei-green fire air duct is a composite aluminum metal duct alternative inorganic glass and steel air duct of a new generation of environmentally friendly energy-saving heat-air duct. The two-tier products from high-strength inorganic cementing material and a layer of insulation material for the substrate, using a special adhesive technology and the structure of the combination of connections. GM-II Wei-green fire board composite air duct board mechanized production, smooth, smooth and improve the efficiency of air transport, air leakage rate of only metal air duct of 10%. GM-II Wei-green fire composite air duct board, whether in production, production, installation, or the use of the process, do not have a material harmful to the environment, not rusty, not moldy, not dust, not breeding bacteria, fungi Fibers and dust-free, odor-free, non-granular, like air pollutants and biological aerosol can effectively improve the indoor air quality. It has excellent fire performance, GM-II Wei-green fire composite air duct and equipped with all the special plastic tubes are class A non-combustible. GM-II Wei-green fire composite air duct is not afraid of water, moist environment does not rust, corrosion does not, even if the bubble in the water products, has managed to maintain a high intensity, wet strength as high as 98%. GM-II Wei-green fire composite tube bending strength of the wind up to 2.5MPa, can withstand wind pressure of 2500Pa to meet the high, medium and low voltage lines to use the wind. GM-II Wei-green fire with the application of the composite plate central air-conditioning, ventilation pipes on the ground floor.
