• Exhaust ducts can be used for range hoods, exhaust pipes, bathrooms, exhaust fans, greenhouses, blowers, dryers, and air conditioners.
• Large-diameter, one-piece molded design; the duct maintains an almost round shape when bent, ensuring low resistance, smooth airflow, and good sealing.
• Flexible ducts use a three-layer structure: outer PVC layer, double-layer aluminum foil, with small pipe wall spacing for long service life. Densely reinforced stainless steel ribs are evenly distributed for greater durability.
• Aluminum foil exhaust ducts are made of fully flame-retardant materials, can withstand high temperatures (-30°C to 100°C), and are resistant to cracking or leakage during use.
• Exhaust ducts are available in various sizes. Ducts with a diameter of 20 cm or less come with a blue plastic gasket, while those over 20 cm do not include the blue plastic gasket.
