The residential building material "Spiral Duct" is a standard product made by Kurimoto Iron Works, designed for air conditioning and exhaust air ducts, with a diameter of φ10mm and a length of 4m. [Features] ○ High Strength The flanges that form the spiral duct have a high reinforcement effect, making it suitable for high-speed ducts, dust collection ducts, and smoke exhaust ducts. ○ Low Friction Loss and Leakage The spiral duct has a high roundness and a smooth inner surface, resulting in extremely low resistance. Additionally, it features a solid lock seam made through mechanical molding, which results in a leakage amount that is only about 1/100 compared to square ducts. ○ Quick Construction Time The connection work for spiral ducts is simple and can be done by anyone, and the ease of hanging them from ceilings contributes to a significantly faster construction time. Furthermore, because they are factory-made, the quality is stable, ensuring reliability in construction. ○ High Economic Efficiency Spiral ducts are mass-produced as standard products in factories, making them inexpensive. Additionally, due to their round shape, which has the smallest surface area, insulation costs are lower for the same area. ● For more details, please contact us.
