Master-PUR H-AE


  •  suction and transport hoses for abrasive solids where resistance to microbes is necessary for example:
  •  rear suction hoses on small sweeping machines, public utility cleansing and refuse collection vehicles
  •  MD lawn mowers
  •  lawn sweepers
  •  leaf suction machines
  •  feed and grain transport
  •  applications where improved pressure and vacuum characteristics is necessary
  •  protection hose against mechanical pressure


  •  highest abrasion resistant by using polyester polyurethane
  •  microbe resistant
  •  gas tight
  •  good chemical resistance
  •  free of halogens and heavy metal
  •  very flexible, reduced weight
  •  small bend radius
  •  nearly smooth inside
  •  optimum flow characteristics
  •  generally good UV and ozone resistance (see register no. 28.7.7)
  •  improved pressure and vacuum characteristics
  •  acc. to TRBS 2153 (zone 1, 21) suitable for non-combustible dusts/bulk goods and gases/liquids of low conductivity. Spiral ends shall be earthed at both sides to ensure static dissipation (see register no. 28.12)
  •  RoHS compliant
