Flat duct

Flat duct

You can save the effort of insulation work and vibration damping installation! Upward and downward, left and right eccentric ducts.

"Flat Duct" is an eccentric type of duct that provides thermal insulation and soundproofing, designed for vertical and horizontal installation. Straight corner ducts can be installed smartly even with vertical and horizontal eccentricities. Additionally, its structure easily absorbs vibrations, inheriting the role previously held by canvas ducts. Moreover, with the included sound-absorbing and thermal insulation materials, installation is completed simply by connecting the ducts. This eliminates the hassle of thermal insulation work and vibration dampening installation. 【Features】 ■ Smart installation possible even with vertical and horizontal eccentricities ■ Structure that easily absorbs vibrations ■ Inherits the role previously held by canvas ducts ■ Installation completed simply by connecting with included sound-absorbing and thermal insulation materials ■ Reduces the hassle of thermal insulation work and vibration dampening installation *For more details, please refer to the PDF document or feel free to contact us.
