We are the manufacturer of aluminium flexible duct and flexible duct connector for air-conditioning and ventilation systems in China, and also the manufacturer of acoustic panel which are sound insulation and fireproof, they are used for sound absorption, building and decoration materials. We have been handling this line for about 10 years, we export our products all over the world. Flexible duct 1)ALUDEC Made of tough aluminium laminated construction encapsulates a high tensil steel wire helix. It is produced for heating, cooling, ventilation, exhaust and air-conditioning systems under low and medium pressure. 2)ISODEC Made of a thermalflex inner wall, supporting 25mm thick 16K high density fiberglass insulation, sheathed in a reinforced aluminium/polyster laminate jacket acting as a vapour barrier. It helps to reduce condensation and heat loss. 3)SONODEC An duct of which the innercore ISODEC has been micro perforated to reduce the noise of air going through the duct. It is easy to install, either on round or oval connectors. 4)COMBIDEC An duct of which the ALUDEC has been covered with non-flammable PVC jacket, produced for heating, cooling, ventilation, air-conditioning, exhaust and dust collection systems under low and medium pressure. Flexible duct connector 1)SLICONE CONNECTOR(WKY) It is a specially developed fiberglass fabric, coated on both sides with silicon rubber. It incorporates a very broad temperature range with outstanding resistance of sunlight, and a wide variety of chemicals. 2)FLUORO-RESIN CONNECTOR(WKF) Coated on both sides with a specially fluorin rubber. Itis specially suited for use in high pressure and high velocity dust systems, and where exposed to toxic fumes or adverse atmospheric conditions. 3)RUBBER CONNECTOR (WKP) Coated on both sides with a specially compounded synthetic rubber. 4)CANVAS CONNECTOR (WKD)Contact: ClarisaMobile:86-13570002229F:86-20-87741046Http://www.zgjitai.com
