Increased strength using fiberglass. Less prone to condensation and lightweight. New sizes φ325 and φ375 have been added, with a lineup from φ100 to φ400 in increments of φ25.
"Atokofureki" is a flexible duct manufactured by Atco Rubber Products in the United States, designed for long lengths with an untreated end, measuring approximately 7.6 meters. The use of three-directional glass fibers on the surface enhances its strength. Because it employs long-fiber glass, it can suppress dust during installation. The inner material consists of double-layered polyethylene terephthalate film, making it resistant to tearing, and its lightweight nature reduces the burden on the structure. 【Features】 ■ Available in sizes from φ100 to φ400 in increments of φ25 (other sizes φ450 and 500 are also available) ■ Obtained non-combustible material certification from the Ministry of Land, Infrastructure, Transport and Tourism (Certification Number: NM-4396-1) ■ Achieved formaldehyde emission grade F☆☆☆☆ *Uses plant-based adhesive for insulation material ■ Uses insulation material with a thermal resistance value (R-value) of 4.2 (calculated in U.S. customary units) ■ Utilizes flexible and strong steel wire in the inner material ■ Compressed and packaged in a polybag for easy transportation, minimizing waste on site Note: The above product may vary slightly in content depending on the branch or sales office, and may not be available at all locations.
