Telescopic air duct LKE410
This product features a composite structure combining high-strength PVC-coated fiberglass fabric (orange-red) with a steel wire framework, reinforced with an abrasion-resistant plastic rib coating for enhanced flexibility and structural support. The tube body is equipped with built-in metal hanging rings (one per meter) and adjustable drawstrings at both ends, enabling rapid connection and secure installation. Rigorous testing confirms compliance with B1-grade flame retardancy standards, with a temperature resistance range of -30°C to 120°C, making it suitable for complex operating conditions involving high temperatures, corrosion, and mechanical wear.
