【High-Grade Material Build】:This ventilation duct hose is constructed with double-layer aluminum foil, paired with internal corrosion-resistant steel wire spirals for reinforcement. The aluminum foil boasts flame-retardant properties, lowering fire hazards in daily operation, while the steel wire core enhances overall structural firmness—avoiding warping and guaranteeing leak-free performance even during prolonged use in changing temperature and humidity conditions.【Broad Application Scenarios】:Ideal for integration into air duct fan systems, covering a wide range of ventilation needs. For residential use: it fits cooker hoods, bathroom and attic ventilation setups, as well as heating and cooling transfer systems. For commercial and industrial use: it works with hydroponic grow tents, electronic factory smoke extraction, blower exhaust systems, and central air conditioning ducting. Its flexible nature lets it adapt to various installation demands, linking different ventilation components seamlessly.【Practical & User-Friendly Design】:The hose offers strong expandability and contractibility, with a maximum expanded length of 3 meters (9.84 feet) to match different space sizes. When not in use, it can be folded into a compact form for easy storage. Customizing its length is simple—only basic tools like scissors or pliers are required, so users can adjust it to project needs without professional support.【Easy Installation Process】:Suitable for users of all skill levels to install. It can be cut to the precise length needed, and the included clamps ensure tight, airtight connections—stopping air leakage and keeping airflow efficient. The smooth, neatly finished ends prevent tangles or snags during installation, and its lightweight design reduces pressure on mounting structures. Tip: Wear gloves to shield hands from sharp edges during setup.【Strong Performance Features】:Thanks to steel wire reinforcement, the hose maintains good self-support after being straightened, eliminating the need for additional brackets. It has low airflow resistance, ensuring smooth air circulation and optimal ventilation efficiency. The material is non-toxic, pollution-free, and corrosion-resistant, making it safe for use in food-related areas or indoor spaces. Its high flexibility allows free adjustment of the duct’s direction during installation, without harming decorative ceilings or walls.【Product Specifications】:[Material]: Double-layer flame-retardant aluminum foil + corrosion-resistant steel wire reinforcement[Length]: Approximately 3m / 9.84ft (expandable)[Inner Diameter Options]: 4in, 6in, 8in[Temperature Resistance]: Maximum 80℃[Key Features]: Flame-retardant, leak-proof, flexible, corrosion-resistant【Package Contents】:1 x Flexible Aluminum Foil Ventilation Duct Hose【Important Reminders】:1.Actual color/appearance may differ slightly from images (lighting/shooting angles)—normal, no quality impact.2.Manual measurement may cause 0-1cm error (length/diameter)—acceptable.
