In a good way! - The fan encasement is made from a duct-like material, but it is much stronger and more rigid. The fan has plenty of room inside the ducting should the encasing ever be dented or deform from mishandling or falling. When I received it, it would rumble loudly throughout the ducting; the issue had something to do with the seating of the fan blade, because I took it off and ran it and the motor itself was silent. I removed the fan blade, applied some oil, and pressed in the blade while tightening the nut which holds it on -- the rumble was reduced significantly. Overall, an excellent fan exhaust fan at a solid price. Any workshop, growery, or perhaps a smoking room could benefit from this addition greatly., especially with the addition of a carbon filter. ## 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; Duct connection note: match duct size to fan diameter for a tight, leak-proof fit – e.g., pair a 4'' fan with 4'' ducting - 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 | #681,056 in Home & Kitchen ( See Top 100 in Home & Kitchen ) | | Brand | VIVOSUN | | Brand Name | VIVOSUN | | Colour | Silver | | Country of Publication | USA | | Customer Reviews | 4.4 out of 5 stars 5,700 Reviews | | Item Dimensions L x W | 7.62L x 0.1W Meters | | Item Length | 300 Inches | | Item Weight | 0.86 Kilograms | | Manufacturer | VIVOSUN | | Material | Aluminium , Stainless Steel | | Material Type | Aluminium, Stainless Steel | | Nominal Wall Thickness | 0.015 inches | | Outside Diameter | 4 Inches | | Product Dimensions | 7.62L x 0.1W Meters | | UPC | 714119464294 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** VIVOSUN - **Colour:** Silver - **Item Length:** 300 Inches - **Item Weight:** 0.86 Kilograms - **Manufacturer:** VIVOSUN - **Material:** Aluminium, Stainless Steel - **Nominal Wall Thickness:** 0.015 inches - **Outside Diameter:** 4 Inches - **Product Dimensions:** 7.62L x 0.1W Meters - **UPC:** 714119464294 ## Images ![VIVOSUN 4 Inch 25 Feet Non-Insulated Flex Air Aluminum Ducting for HVAC Ventilation w/Two 4 Inch Stainless Steel Clamps - Image 1](https://m.media-amazon.com/images/I/81tukyxgzVL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this be ok for a portable a.c.?** A: No!
