Strong, flexible hose medium wall thickness, intended for discharge dust, sawdust, chips, bulk materials, granulate etc. Dla all types industry, in particular often used for discharge chips and other particles solid in industry wood, furniture, ceramic, plastics. dense spiral reinforcing ensures greater resistance to vacuum in ratio for hoses ECO 0.4 and ECO 0.6. pliable, less compressible, smooth inside and flexible – also in low temperatures. O sound resistance to abrasion, resistant also on microbes and hydrolysis. Not toxic, Contains no halogen compounds or plasticisers. Resistant to oils and petrol. hose marked is an arrow indicating correct direction flow medium. The hose wall thickness is measured between the spiral. Assembly on connectors with bridge clamps (prawo-handed). Other diameters may be available on special order. hose Available is in following versions: ECO – version standard, ECO SE – version with material flame-retardant (UL94 V-2), ECO AS – version permanently antistatic ISO 8031: R 9 Ω, TRGS 727 (6.4.2.4): R 8 Ωm, directive 2014/34/EU (ATEX): It can be used in defined zones hazard explosion po analysis risk, ECO SE AS – version antistatic and flame-retardant (Available on special order). hose ECO produced is in process production compliant with with policy sustainable growth in which uses raw materials originating with recycling pure waste with process production, energy renewable, closed circulation water and other innovation. Hose material: transparent polyether-polyurethane. Reinforcement: spiral with wire steel. Wall thickness measured between the spiral: 0.7 mm. Operating temperature: od -40°C up to +100°C (momentarily for + 125°C).
