This ultra-lightweight and highly flexible hose is engineered for demanding industrial environments, ensuring reliable transport of air, smoke, fiber dust, dirt, and other lightweight particles. Crafted from conductive polyethylene (PE) combined with elastomer, it offers exceptionally low material resistance, making it the perfect solution wherever the prevention of electrostatic charge build-up is crucial. Its integrated left-handed reinforcing spiral not only strengthens the structure but also enables quick and secure connection with left-threaded vacuum fittings, such as plastic EVA hose connectors in DN32, DN38, and DN50, or specialized conductive fittings. For added versatility, the hose can also be mounted using clamps, pipe fittings, or other compatible accessories. Certified for diameters DN38 and DN50 in accordance with ATEX requirements and TRGS 727 standards, it is approved for use in explosion-risk zones, provided effective grounding and user risk assessment are ensured. With a durable black PE and elastomer construction, operating temperature range from -20°C to +60°C, and dependable performance under varying vacuum conditions, this hose combines safety, efficiency, and adaptability to meet the highest industrial standards.
