Master-PUR L-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 transport
  •  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
  • lightweight
  • extremely flexible
  • small bend radius
  • nearly smooth inside
  • generally good UV and ozone resistance (see register no. 28.7.7)
  • optimum flow characteristics
  • acc. to TRBS 2153 (zone 20) suitable for combustible dusts/bulk goods. Spiral ends shall be earthed at both sides to ensure static dissipation (see register no. 28.12)
  • RoHS compliant
