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. 3.5 mm

Applications

● Suction & Transport Hose for quarries,
cement works, shipyards and docks

● Flat roof gravelling

● Working Hose for silo vehicles and cargo
depots

● Refurbishment of rail systems

● Roof green covering

● Vacuum/suction vehicles

● gas-tight

● high tensile strength

● optimum flow characteristics

● extremely abrasion-resistant

● smooth inner lining

● acc. to TRBS 2153 (Zone 20) for nonflammble
dust/bulk solids for conducting
electrostatic charges when earthed at both
ends of the spiral
