Efficient hose solutions for use on industrial vacuum cleaners

Suction hoses used on industrial vacuum cleaners are subjected to continuous high loads. Industrial vacuum cleaners in contact with severe contamination must withstand extreme stress levels and their suction power is designed for abrasive and coarse materials: pebble stones, rubble, metal swarf, leaves and liquids all have to be removed efficiently.

NORRES industrial hoses provide efficient solutions

There is considerable demand for industry-specific hose solutions. NORRES suction hoses made from polyurethane, EVA or PVC are ideal for use on industrial vacuum cleaners, where they have to withstand heavy loads, for example when exhausting hot or coarse abrasive dirt, coal dust or liquids or possibly combinations of these. The hose manufacturer has a range of quality products for this purpose, with important benefits for owners such as a long service life and significantly extended replacement intervals in heavy-duty applications.

For the throughput of abrasive bulk material the AIRDUC® PUR 355 AS WEAR STRIP (HD) has proven itself continuously. The special feature: The hose type has a external abrasion protection via external helix - thus it serves important product properties at the same time: It protects floors and surfaces, prolongs service life, it is easy to use and is user-friendly. In addition, it is certified according to TRGS 727 & ATEX 2014/34/EU (1999/92/EC), is highly abrasion-resistant and can be used in a temperature range of -40°C to 90°C - briefly up to 125°C.

Industrial vacuum cleaners are also optimally equipped with AIRDUC® PUR 355 AS TWIN COLOR (HD): The wall of the hose is permanently antistatic according to ISO 8031 and its volume and surface resistance is <10⁹ (according to TRGS 727 <2.5*10⁸ Ω*m and NFPA 652 10⁸-10⁹ Ω)*. The hose is certified to TRGS 727 and ATEX 2014/34/EU (1999/92/EC). The TWIN COLOR hose series offers the user the option to colour the hose in two specific colours. The hose can thus be customised in colour according to customer requirements. Every colour combination can be realised.

Both hose types - AIRDUC® PUR 355 AS WEAR STRIP (HD) and AIRDUC® PUR 355 AS TWIN COLOR (HD) are available in the standard version AS transparent for use on industrial vacuum cleaners.

The AIRDUC® PUR 351 EC (MD) convinces in explosion hazard areas by its easy handling and long service life as well as electrically conductive walls with contact resistance and surface resistance <10³ Ω.

Highly flexible - thanks to the special SuperFlex construction - and in a lightweight version, the SuperFlex PVC 372 also allows easy handling.

The AIRDUC® PUR 355 EC (HD) in heavy-duty has proven itself time and again in use. The extraction hose is electrically conductive, highly abrasion-resistant and optimally suited for the extraction of high throughput and abrasive materials. The CONNECT 240 EC is the ideal supplement. The soft sleeve to slide onto connectors or push into pipes can be installed easily and quickly. CONNECT 240 EC is reusable in the threaded version. In addition: CONNECT 240 EC is electrically conductive with a contact resistance and surface resistance <10³ Ω.

With the CLAMP 212 EC bridge clamp, grounding is possible without exposing spiral and without damaging hose, it is easy and quick to install and as a special benefit, CLAMP 212 EC is reusable.

Hoses with a wall made of EVA have proven themselves in use under extreme conditions. The hose models EVA 373 AS and EVA 373 EC are therefore the typical hoses for industrial vacuum cleaners: crush resistant, floatable and highly flexible. The antistatic or electrically conductive version is ideally suited for the extraction of coal dust or similar explosive materials.
