The AIRDUC® PUR 351 EC is a high-quality, electrically conductive polyurethane hose designed for a wide range of industrial applications where both high mechanical strength and reliable dissipation of electrostatic charges are crucial.

All variants are made from high-quality polyurethane with very high abrasion resistance, making the hose ideally suited for dusty, granular or abrasive media. The materials remain flexible even at low temperatures and ensure reliable operation even in cooling zones or cold environments.

A key feature of all EC versions is the electrically conductive wall with a volume and surface resistance of < 10³ ohms, making the hose ideal for applications where sparking and electrostatic risks must be avoided at all costs. This is particularly relevant in EX/ATEX zones, in conveying systems for powders and granulates, or when extracting flammable media.

Typical areas of application:

Extraction and conveyance of abrasive dusts, swarf and particles
Pneumatic conveying systems for powders, granulates and plastic materials
Use in EX-/ATEX zones
Chemical and pharmaceutical production
Mechanical and plant engineering
Mobile and stationary extraction systems
Applications involving strong vibrations or demanding motion sequences (351 EC)

Advantages of the AIRDUC® PUR EC:

electrically conductive (< 10³ ohms)
very high abrasion resistance
Excellent cold flexibility
Graded mechanical robustness depending on the version
Smooth inner surface for optimised flow
resistant to oils, fuels and many chemicals
