A PU (Polyurethane) Duct Hose is a highly flexible, lightweight, and abrasion-resistant hose designed for the efficient movement of air, dust, fumes, wood chips, powders, and light granules. Made from premium-grade polyurethane, it offers excellent mechanical strength, transparency, and chemical resistance. The hose is typically reinforced with a spring steel wire helix, making it crush-resistant and suitable for both suction and light-pressure applications. It’s widely used in woodworking, plastics, textile, and dust collection systems.
