[Example] Waterproof zipper AQUASEAL(R): Tunnel exhaust duct
Eliminate air leakage at the connection points of the exhaust duct! With our fasteners, we have reduced air leakage to one-hundredth, successfully omitting the need for intermediate fans and reducing energy consumption.
Our AQUASEAL® zippers are widely used in applications requiring waterproofing, such as wetsuits, waterproof bags, and cooler bags. ◆ Background of Adoption in Tunnel Exhaust Ducts Exhaust ducts used in tunnel construction are extended by connecting them with zippers every 10 meters. However, due to frequent "air leaks" from the zippers, large fans or intermediate fans may be necessary. When the duct is long or the cross-sectional area of the tunnel is small, it becomes difficult to install intermediate fans. ◆ Key to Solving the Problem (How Fastening Helped) By adopting AQUASEAL® zippers at the connection points of the ducts, we successfully reduced air leakage to one-hundredth compared to conventional products. This led to the omission of intermediate fans and a reduction in electrical energy consumption. *For product details, please refer to the catalog available for download below. *AQUASEAL is a registered trademark of YKK Corporation.
