Shop VIVOSUN Flex Air Aluminum Duct for Ventilation 4 Inch 25 Feet, 2 Clamps Included, Long Heavy-Duty Multi-Layer Dryer Hose Vent Kit, Duct Fan Systems. Review: This 4-inch aluminum foil ducting is extremely well made and far sturdier than I expected. The aluminum layering feels thick and reinforced, not cheap or flimsy, and it holds its shape perfectly once installed. I really like the black outer layer—it looks clean, professional, and helps with light control compared to standard silver ducting. The hose is flexible enough to route easily, yet strong enough that it doesn’t collapse or kink. The 8-foot length was perfect for my setup, and the included clamps fit snug and secure with no air leaks. Overall, this is a high-quality, heavy-duty vent hose that feels reliable and built to last. Great for HVAC, dryer vents, or exhaust fan systems. I would absolutely buy this again and recommend it to anyone looking for durable, trustworthy ducting. Review: Inspiriert durch Manfred Welding hat mein Keller nun auch eine Absauganlage erhalten. Der Schlauch ist solide aber nicht störrisch. Er lässt sich gut durchschneiden und auch über den Tisch bewegen. Als Einsaugtrichter habe ich mir aus 20x20mm Quadratrohr einen Halter geschweißt. Damit kann ich jetzt überall auf dem Tisch einfach den Schlauch Positionieren. Generell ist ein Staubsauger schon ein muss, sofern das Werkzeug einen Anschluss dafür hat. Da das aber nicht 100%ig alles einfängt und z.b. beim Laserreinigen der Arbeitsbereich zu groß dafür ist, wird das jetzt damit gemacht. ## Features - Perfect Connector: This ducting is primarily used with duct fan systems in various air circulation and ventilation projects to move and transport air, increasing airflow and easing connections between spaces; It's compatible with front-mounted and top-loading dryers/fans - Premium Material: Made of aluminum, it is resistant to high-temperature and corrosion-resistant, being able to serve for a long time; The stainless steel clamps are rustproof, corrosion-resistant, and heavy-duty, ensuring a seamless junction - Multi-Layer Protection: It features multi-layer protection, making it more durable and resistant to leaks than single-layer ones; The internal and outer layers are made of heavy-duty aluminum foil that is fire/flame-retardant; Its middle layer adopts PET thermoplastic that protects the ducting from cuts and tears, all while stopping leakage - Flexible and Convenient: Thanks to the built-in steel wire, the length and shape of this ducting is flexible to change for fitting exhaust fan blower or inline fan; Being portable and lightweight, it can be installed at any place; Comes with 2 duct clamps in the same duct opening size for easy setup and securer connection - Abundant Applications: Suitable for both commercial and residential air duct solutions; Widely used in HVAC applications, bathroom venting, stove exhaust, dryer ventilation, kitchen cooking exhaust, planting room, or warmhouse air circulation, etc.; Also used to cool AV equipment rooms, closets, racks, and cabinets ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01EUURUVM | | Best Sellers Rank | 252,681 in DIY & Tools ( See Top 100 in DIY & Tools ) 684 in Ducting | | Brand | VIVOSUN | | Colour | Silver | | Country of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (8,067) | | Item Dimensions L x W | 7.62L x 0.1W metres | | Item Length | 10.2 Centimetres | | Item Weight | 0.86 Kilograms | | Manufacturer | VIVOSUN | | Material | Aluminium | | Maximum Pressure | 5 Bars | | Nominal Wall Thickness | 0.015 inches | | Outside Diameter | 10.2 Centimetres | | UPC | 714119464294 | | Unit Count | 25.0 meter | ## Product Details - **Brand:** VIVOSUN - **Colour:** Silver - **Item length:** 10.2 Centimetres - **Item weight:** 0.86 Kilograms - **Material:** Aluminium - **Maximum pressure:** 5 Bars - **Nominal wall thickness:** 0.015 inches - **Outside diameter:** 10.2 Centimetres - **Product dimensions:** 7.62L x 0.1W metres - **UPC:** 714119464294 ## Images ![– Flex Air Aluminum Duct for Ventilation 4 Inch 25 Feet, 2 Clamps Included, Long Heavy-Duty Multi-Layer Dryer Hose Vent Kit, Duct Fan Systems - Image 1](https://m.media-amazon.com/images/I/81tukyxgzVL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Will this be ok for a portable a.c.?** A: No!
