This lightweight and highly flexible hose, crafted from soft gray PVC with internal micro-grooves and reinforced by a durable right-hand spiral of rigid PVC, ensures reliable performance in demanding industrial environments. Engineered for the efficient extraction of polluted air, smoke, dust, chips, and textile fibers, it provides a versatile solution for a wide range of applications, from manufacturing plants to workshops requiring clean and safe air circulation. Its smooth interior supports optimal airflow, while the robust spiral reinforcement guarantees excellent resistance to crushing and mechanical stress. The hose is self-extinguishing and flame-retardant, meeting the stringent UL 94 V-2 flammability standard, which enhances workplace safety and compliance. Easy to install with clamps, pipe fittings, or other standard connectors, it offers both convenience and durability in everyday use. With a wall thickness measured between spirals and an operating temperature range from -10°C to +60°C, it adapts seamlessly to varying conditions, maintaining efficiency even under fluctuating vacuum levels. This combination of flexibility, safety, and resilience makes it an indispensable component for industries seeking reliable air and dust extraction solutions.
