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.
3.2 - 4.8 mm depending on DN

Applications

● Suction/extraction of glass splinters, glass
wool, mineral wool, slag, mill scale and
sinter

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