Applications

Abrasion-proof and electrically conductive suction and transport hose, especially suitable:

• in areas liable to contain explosive mixtures (explosion protection)

• for abrasive solids such as dust, powder, fibres, chips and granulates

• for gaseous and liquid media

• for de-dusting and suction plants, industrial vacuum cleaners, suction of paper and textile fibres

• as resistant protection hose

Properties

• according to TRBS 2153 electrically conductive wall: electrical and surface resistance < 10³ Ω, recommended for conveying of inflammable bulk materials

• light model

• highly abrasion-proof (abrasion resistance about 2.5 to 5 times better than most rubber materials and about 3 to 4 times better than most soft PVC´s)

• smooth interior

• optimized flow properties

• flexible

• high tensile strength and tear resistant

• good resistance to mineral oils and gasoline

• Good resistance to chemicals (refer to section 14.1)

• good resistance to UV and ozone (see chapt. 14.8)

• small bending radius

• kink-proof

• free of softener and halogen

• gas and liquid tight

• very robust

• conforms to the requirements of the European ATEX guideline

• conform to RoHS guideline
