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
flow rate
● For abrasive solids, gaseous and liquid
media
● Standard hose for industrial vacuum
cleaners
● 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 nonflammble
dust/bulk solids for conducting
electrostatic charges when earthed at both
ends of the spiral
● microbe-resistant
● antistatic, surface resistance < 109 Ohm

Temperature Range
● –40°C to +90°C
● peaks to +125°C
