A brand new series of NORRES Protape® ATEX-PUR330-MHF/AS ATEX permanent anti static and abrasion proof suction and blast hoses is now available from Flextraction Ltd, suppliers and manufacturers of Local Exhaust Ventilation (LEV) products and authorised distributor of flexible extraction hoses in the UK and Ireland for NORRES Schlauchtechnik GmbH & Co.KG, the Gelsenkirchen, Germany based manufacturer of technical and industrial hoses.
These highly flexible, super lightweight, ATEX approved hoses incorporate optimised flow properties, are designed to convey inflammable particles, chippings, powder, dust, oil vapours and welding fumes in a multitude of applications and industries ranging from de-dusting and suction plants, industrial vacuum cleaners, air-conditioning and ventilation applications, paint fume extraction, food industry applications, wood processing applications, granulate conveying systems, engine exhaust systems, chemical extraction systems to manufacturing and surface finishing applications. For food industry applications they meet EC guideline 2002/72/EC.
They are constructed using PROTAPE® tape hose and spiral sprung steel wire in special PRE-PUR® premium ether-polyurethane walls having an approximate thickness of 0.6mm. By being permanently anti-static, electro-static charging (separation of charged particles) cannot occur thereby eliminating any discharges that can ignite an explosive mixture of gas, vapour, mist or dust, dangerous or unpredictable behaviour caused by shock when this discharge takes place via the human body, process disruptions caused by the medium sticking to the hose wall or the malfunction of measuring devices and controllers. The average operating temperature range is between approx. -40°C to +90°C, but can be used over short working periods with temperatures up to +125°C.
Other features include a long working life, in that they have abrasive resistance about 2.5 – 5 times better than most rubber materials and are also about 3 to 4 times better than most soft PVC’s, microbe and hydrosols resistant as well as being PVC free.
