Applications

Abrasion-proof suction and transport hose, especially suitable:

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

• for gaseous and liquid media

• for public utility street cleaning vehicles

• for lawnmowers, grass sweeping machines and leaves exhaust

• for fodder transport

Properties

• 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

• food quality wall complies with: FDA 21 CFR 177.2600 and 178.2010, EC guideline 2002/72/EC incl. the latest amendment 2007/19/EC, German guideline XXXIX BfR polyurethane (see chapt. 14.5)

• approval according to EC guideline 2002/72/EC incl. the latest amendment 2007/19/EC for the complete hose by independent institute (see chapt. 14.5)

• microbe and hydrolysis 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)

• very good low temperature flexibility (better than comparable ester-polyurethanes)

• small bending radius

• kink-proof

• free of softener and halogen

• gas and liquid tight

• conform to RoHS guideline

• according to TRBS 2153 (formerly BGR 132): capable of electro-static discharge by grounding the spiral, recommended for many applications with the exception of inflammable bulk materials

Construction

2.2.5-AIRDUC-®-PUR-350-MHF

AIRDUC® profile hose (see chapt. 0.2):

1. spring steel wire firmly embedded in wall

2. profile with optimized flow properties

3. wall thickness 0.7 mm approx.

Material

• wall: special premium ether-polyurethane (Pre-PUR® see chapt. 0.4)

• spiral: spring steel wire

Temperature Range

• -40 °C approx. to +90 °C approx.

• short time to +125 °C approx.

Delivery variants

• transparent (standard)

• special colours: full coloured

• customer-specific product marking

• according to TRBS 2153 antistatic wall: electrical and surface resistance < 10⁹ Ω due to permanently antistatic material without migration
