Noise Reducing Insulated Flexible Duct, Black Aluminum Foil by Hon&Guan

【High-Quality Material】Flexible ducting crafted with 1 layer of PVC, 2 layers of aluminum foil, 1 layer of centrifugally glass wool, and a steel wire helix for shape retention. 【Noise Reduction】Hon&Guan's Noise Reducer Silencer is engineered to minimize noise from fans and carbon filter systems, reducing it by up to 50%. The inner holes in the aluminum foil layer help reduce noise by allowing sound waves to escape instead of reflecting and amplifying within the hose. 【Thermal Insulation】Ideal for heat preservation, cooling, and ventilation, this Flex Duct offers excellent thermal insulation, compatible with portable AC devices, and withstands temperatures from -22°F to 302°F (-30°C to 150°C). 【Corrosion-Resistant and Durable】A thick layer of PVC and 2 layers of aluminum prevent gas leaks, suitable for extractor and inline duct fans, carbon filters, and boat blower hoses. 【Versatile Applications】Hon&Guan's dryer vent hose is perfect for HVAC systems, moving and delivering air in kitchens, greenhouses, grow rooms, bathrooms, dryer rooms, grow tents, and more.
