Flexible duct with glass wool insulation "Fujirex"

Flexible duct with glass wool insulation "Fujirex"

Products with non-combustible certification are suitable for buildings with 'quasi-fire-resistant structure' according to the regulations!

The glass wool insulation material-equipped flexible duct "Fujirex" is a flexible duct with insulation performance. Additionally, it has obtained non-combustibility certification from the Ministry of Land, Infrastructure, Transport and Tourism and is composed of materials that are "not subject to notification and not regulated." Furthermore, because it meets the following standards, it is very effective when the planned building is of "quasi-fire-resistant structure": - The outside of the duct is covered with rock wool insulation, glass wool insulation, etc. - The outside of the duct is covered with gypsum board or a steel frame. - The duct itself is made of non-combustible or quasi-non-combustible materials. 【Features】 ■ Insulation performance ■ Certified non-combustible product ■ Does not use any materials containing formaldehyde ■ Length can be set freely up to a standard length of 10m ■ Eliminates the need for cutting on-site, effectively reducing construction time and waste *For more details, please download the materials or feel free to contact us.

Flexible duct for high pressure 2 (up to +2500Pa)

Flexible duct for high pressure 2 (up to +2500Pa)

The internal moisture does not penetrate the GW, and it also has excellent corrosion resistance.

The flexible duct for high pressure 2 (up to +2500Pa) prevents internal moisture from penetrating the GW and has excellent corrosion resistance. It is ideal for exhaust and ventilation systems dealing with chemicals and humidity. The Silverflex AD-G/AL-AD-G (shown in the photo) uses PET film coated with aluminum on the inner surface, making it suitable for the primary side of VAV and clean rooms. Additionally, the Hyperflex HY-G is formed by thermally bonding a PVC (polyvinyl chloride) coated sheet to the inner surface. The Hyperflex AL-HY-G prevents pinholes caused by welding sparks during installation due to its aluminum coating on the outer surface. It also uses a PVC (polyvinyl chloride) coated sheet on the inner surface. For more details, please contact us or refer to the catalog.

Flexible duct, branching type flex, Sortaflex.

Flexible duct, branching type flex, Sortaflex.

Prefabricated flexible duct with special processing applied to the branch pipe and main pipe ends.

The bifurcation-type flex, Souterflex, is a flexible duct that incorporates a branching branch pipe, eliminating the need for the branching box traditionally used in construction methods. Insulation work (band wrapping work) after duct connection is also unnecessary, contributing to a reduction in labor and construction costs. You can choose from various specifications based on flexible ducts manufactured by Arai Jitsugyo Co., Ltd., both for the external covering and the inner surface. Examples of main pipe end processing include reducer processing, single drop pipe installation, and closed processing. It is also possible to set up three or more branch pipes. For more details, please contact us or refer to the catalog.
