Flexible Air Duct "U-Lock"

Flexible Air Duct "U-Lock"

Since the metal band is not exposed internally, it does not come into contact with the medium inside the duct, preventing corrosion and other issues.

The "U-Lock" is a flexible air duct widely used in the United States, Canada, and European countries as an industrial duct. Compared to traditional ducts that use adhesives, it has better airtightness and excels in heat resistance, chemical resistance, and durability. Furthermore, since the metal band (helix) is not exposed inside, it does not come into contact with the medium inside the duct, preventing corrosion and other issues. The interior of the duct is smooth, resulting in low resistance, which is also a characteristic. 【Features】 ■ High performance in the industrial sector ■ Better airtightness compared to traditional ducts that use adhesives ■ Excellent heat resistance, chemical resistance, and durability ■ Smooth interior with low resistance ■ Reinforced outer circumference of the duct by the metal band, making it resistant to crushing and bending *For more details, please refer to the PDF document or feel free to contact us.
