Ducts for air conditioning, ventilation, dust removal, and deodorizing devices, such as chimneys!
The "spiral duct" is continuously manufactured by winding a hoop of 0.5 to 1.6 mm in a spiral shape and overlapping and fixing both ends with a crimp. As a result, four strips of steel overlap to form a tubular shape in a spiral manner, with the outer strips reinforcing the duct body. 【Connection Method】 ■ Cut the spiral duct to fit the usage situation, insert separately sold nipples and 45° or 90° elbows, and secure them with 3 to 4 sheet metal screws. ■ Wrap duct tape or aluminum tape 2 to 3 times to prevent air leakage. *For more details, please refer to the PDF document or feel free to contact us.
