大久保設備工業 List of Products and Services

At Okubo Equipment Industry, we conduct thorough on-site surveys prior to the installation of spiral ducts. By performing all processing work at our factory, we adopt a prefabricated processing method that allows for installation work only at the site. 【Benefits】 ■ Shortened construction period - Since processing is done collectively at the factory, we can significantly reduce the time spent on-site. - Installation on-site is easy. ■ Reduction in labor hours - As processing work on-site is unnecessary, we can lower labor hours. ■ Environmentally friendly on-site conditions - There is no generation of waste materials since on-site processing is not required. - We can eliminate noise and metal dust generated from processing work.

The "Spiral Elbow" is a spiral (round) duct used in the corner sections of building air conditioning and ventilation systems. Unlike conventional pressed elbows (made from two pressed steel plates) or welded elbows (made from welded parts), it is manufactured by spirally winding steel plates, which maintains higher strength and airtightness compared to traditional products. Additionally, the streamlining of the manufacturing process enables mass production and shorter delivery times. 【Features】 ■ No waste material is produced, and the manufacturing process is simplified ・ Can be offered at a low cost ■ Usable in air ventilation systems of all types of buildings ■ Exhibits high strength and airtightness ・ Manufactured by spirally winding steel plates For more details, please contact us or refer to the catalog.
