Durable PVC Coated Aluminium Duct Hose for HVAC, fume extraction, and ventilation with superior condensation resistance. PVC Coated Aluminium Duct Hose (COMBI) Description “COMBI” is a flexible aluminium duct made from multi-layer aluminium and polyester, reinforced with high-tension steel spring wire, and covered with a PVC layer. “COMBI” is recommended for discharging welding fumes, and for low to medium pressure, heating, cooling and air conditioning systems. The PVC layer provides better protection against condensation compared to standard non-insulated ducts. It helps maintain indoor air quality by preventing mold growth and corrosion caused by condensation. The PVC layer also enhances resistance to punctures and tears, combined with fire resistance makes COMBI a fire-resistant ventilation duct suitable for HVAC and industrial applications. “COMBI” is elastic and flexible and can be easily fitted to circular, oval or rectangular connectors. Its dimensions, tolerances and mechanical resistance are tested and certified according to EN 13180 standards Applications HVAC Systems: Suitable for heating, ventilation, air conditioning, exhaust, and return air ducts. Industrial: Industrial fume extraction hose ideal for fume extraction, dust collection, and venting chemical fumes. Home: Ideal for dryer venting in laundry facilities. Agriculture: Ventilates barns and animal enclosures. Marine and Shipbuilding: Used in ventilation systems on ships and marine vessels; corrosion-resistant for harsh environments. Construction: Temporary ducting for dust control, ventilation, and dehumidification. Commercial Kitchens: Vents smoke, heat, and grease-laden air outside. Salient Features Aluminium Laminated Inner Flexible Duct UV-resistant and chemical-resistant Flexible and Seamless Construction Easy to transport, install, and store. Airtight and low maintenance. Smooth Inner Surface Minimizes pressure loss, anti-static, and dust-proof. High Tension Steel Wire High resistance to deformation and durable. PVC Sleeve High resistance to wear, mechanical stress, UV rays, and chemicals.
