Material spiral: spring steel wire wall: pure polyester polyurethane (acc. to DIN ISO 4649 more abrasion-resistant in comparison to polyether polyurethane) wall thickness between spirals approx. 1.4 mm Applications ● Suction of coarse-grained media with high ● for abrasive solids, gaseous and liquid ● Standard hose for industrial vacuum ● Granulate transport hose ● Transport of chips/shavings ● Suction and transport of paper fibres ● Oil mist extraction/suction | Properties ● highly abrasion-resistant ● generally good UV and ozone resistance ● oil/petroleum-proof ● free of halogens and plasticizers ● gas-tight ● extremely flexible, lightweight ● small bending radii ● increased pressure and vacuum resistance ● high tensile strength ● mostly smooth inner lining ● optimum flow characteristics ●acc. to TRBS 2153 (Zone 20) for non- flammble dust/bulk solids for conductingelectrostatic charges when earthed at both ends of the spiral ● microbe-resistant ● antistatic, surface resistance < 10 Temperature Range ● -40°C to +90°C ● peaks to +125°C |
