Flexible duct, branching type flexible, Sortaflex.

Flexible duct, branching type flexible, Sortaflex.

This is a 'prefabricated flexible duct' with special processing applied to the branch pipe and main pipe end.

The branching type flexible duct, Souterflex, incorporates a branching branch pipe, eliminating the need for the branching box traditionally used in construction methods. This also removes the need for insulation work (band wrapping work) after duct connection, 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 internal 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.

Natural lighting system: "light duct" that allows sunlight to pour into the building.

Natural lighting system: "light duct" that allows sunlight to pour into the building.

A life filled with pleasant light by incorporating natural light as indoor lighting. Solving the challenges of skylights, with no maintenance required. No electricity needed and UV rays are also cut.

<Features> ■Reduction of daytime power consumption: Key to lighting By utilizing natural light directly for illumination, no electricity is needed. This is particularly effective in areas where lighting is required during the day, with some installations achieving an 80-90% reduction in artificial lighting. ■Maintenance-free: No performance degradation for about 20 years after installation Light ducts that have not undergone maintenance or cleaning for approximately 20 years continue to maintain their performance and emit light. Thorough durability testing and structural innovations have made maintenance-free operation possible. <Applicable Scenes> ■In lower floors of school buildings: A spacious educational environment under natural light The core areas of lower floors, where natural light is difficult to obtain, are one of the cases where light ducts are most effective. This is for creating an educational environment where children can grow freely. ■Renovating skylights to light ducts: Brightness increased sixfold We solved the customer's concern about dark hallways despite having skylights by using light ducts. The results are clear, with brightness increasing by approximately six times, allowing visibility in every corner of the hallway. *For detailed specifications, please download the PDF catalog or feel free to contact us.

Duct specifications

Duct specifications

Introducing "duct classification" and "the pitch of spiral duct seams"!

Here is an introduction to the specifications of ducts. The classification of ducts is as follows: "Low-pressure ducts" have a positive pressure of 500 or less and a negative pressure within -500. "High-pressure 1 ducts" exceed a positive pressure of 500 but are 1,000 or less, and have a negative pressure exceeding -500 but within -1,000. "High-pressure 2 ducts" exceed a positive pressure of 1,000 but are 2,500 or less, and have a negative pressure exceeding -1,000 but within -2,000. Additionally, we provide information on "the thickness of straight pipes for spiral ducts," "the thickness of joints for spiral ducts," and "joining materials" in a PDF document, so please refer to it for more details. 【Duct Classification】 ■ Low-pressure duct ・Positive pressure: 500 or less / Negative pressure: within -500 ■ High-pressure 1 duct ・Positive pressure: exceeding 500 but 1,000 or less / Negative pressure: exceeding -500 but within -1,000 ■ High-pressure 2 duct ・Positive pressure: exceeding 1,000 but 2,500 or less / Negative pressure: exceeding -1,000 but within -2,000 *For more details, please refer to the PDF document or feel free to contact us.
