Choosing the right hose is vitally important when it comes to dust and fume extraction, and a decisive factor for achieving a long service life and optimum performance. Industrial hoses used for dust and fume extraction are exposed to high loads. They are primarily employed to extract and transport gaseous materials or fine dusts. Temperature resistance, flexibility, flame retardancy and impermeability are the most important hose properties for applications in this industry.

Hose solutions for extreme conditions

A long service life and significantly extended replacement intervals for heavy-duty suction and blast hoses present daunting challenges for manufacturers serving the dust and fume extraction sector, for example, where temperature resistance is a top priority. When it comes to suction and blast hoses for this industry, the NORRES Group relies on proven quality and specialises in efficient solutions leading to sustainable cost reductions.

The PROTAPE^® PUR 301 AS is a highly flexible and super-lightweight hose. It is flame retardant according to UL94-HB and DIN 4102-B1. The PROTAPE^® PUR 301 AS additionally has a permanently antistatic wall with an electrical and surface resistance of <10⁹ Ω in accordance with ISO 8031. TRGS 727 and ATEX 2014/34/EU (1999/92/EC) certification: for the aspiration of combustible dust (Zone 22 indoor), for conveying non-flammable liquids for use in Zones 1 & 2 (gases). The PROTAPE^® PUR 330 AS is particularly suitable for use on extraction units as well as dedusting and filter systems or for oil mist and galvanic extraction owing to a combination of high flexibility and high abrasion resistance and flame retardancy. The hose wall is permanently antistatic, with an electrical and surface resistance of <10⁹ Ω in accordance with ISO 8031. The hose additionally has TRGS 727 and ATEX 2014/34/EU certification.* The AIRDUC^® PUR 350 AS BLACK is the optimal hose solution for pneumatic transport of flammable bulk materials, with a temperature range from -40°C to +90°C (short time to +125°C) as well as TRGS 727 and ATEX 2014/34/EU certification.* On extraction arms or for welding fume extraction, properties such as high flexibility, a super-lightweight design, flame retardancy and very good heat resistance, as offered by the PROTAPE^® PVC 371 HT ventilation hose, are indispensable. The CLAMP 210 BRIDGE CLAMP complements these products perfectly. It is ideal for attaching lightweight hoses. Thanks to its special bridge geometry, the clamp enables practically leak-proof and secure clamping. It is fitted quickly and easily, and it is also re-usable.
