This lightweight and highly flexible hose is engineered for the efficient transport of air, dust, powders, wood shavings, fine chips, and other light bulk materials, making it an ideal solution for the woodworking and furniture industries, while also perfectly suited for a wide range of industrial applications. Manufactured from transparent polyester-polyurethane with a durable steel wire spiral reinforcement, it combines excellent abrasion resistance with resistance to oils, gasoline, microbes, and hydrolysis, ensuring long-lasting performance even in demanding environments. Its smooth inner surface supports optimal flow, while its flexibility and elasticity are maintained even at low temperatures, guaranteeing reliable operation from -40°C to +100°C, withstanding peaks up to +125°C. The hose is permanently antistatic in compliance with ISO 8031 and TRGS 727, and after proper double grounding of the spiral, it can be treated as electrically conductive, meeting ATEX requirements for use in specific explosion hazard zones. Additionally, it is flame-retardant according to DIN 4102 class B1, halogen- and plasticizer-free, and designed with a marked flow direction for safe and efficient installation. Less compressible than the SMARTFLEX® 0.4 yet smoother inside, it ensures improved material transport and reduced wear. Available in standard diameters with the option of custom sizes on request, it is installed easily with bridge clamps (right-handed), offering a professional, safe, and versatile solution for modern industrial needs.
