ATEX extraction arms can be specified for zone 1 and zone 21 areas for use with explosive gases, dust and chemicals.
ATEX extraction arms can be specified for Zone 0, Zone 1 and Zone 2 areas for use with explosive gases, dust and chemicals and fall in line with the ATEX directive 94/9/EC category 2. ATEX extraction arms are manufactured with flexible hose and feature an externally-mounted, self-supporting structure, made from non-EX coated stainless steel metal parts and are available in four varieties of diameters, including 100mm, 125mm, 160mm and 200mm and in a wide variety of lengths, from 1,500mm to 7,000mm.
According to HSE’s Explosive Atmospheres – Classification of Hazardous Areas (Zoning) and Selection of Equipment guidance, “Gases, vapours, mists and dust can form explosive atmospheres within the workplace air. Hazardous area classifications are used to identify and locate areas where potentially explosive atmospheres are so that special precautions can be made to prevent fires and explosions. Risk assessments should be completed to identify areas where ATEX zones and which classification they are. In the document, it continues on to recommend that mechanical ventilation, typically local exhaust ventilation (LEV), can dilute and remove dangerous substances from an enclosed working area. There’s a close link between the ATEX classification, the area surrounding the zone and LEV location; as well-designed LEV may prevent the need for a zoned area, as it may reduce it so it has a negligible extent.
Auto Extract Systems can provide a wide variety of ATEX extraction arms that form complete local exhaust ventilation (LEV) systems that are suitable for all kinds of ATEX-rated working environments.
ATEX extraction arms should be utilised in conjunction with one of our centrifugal fans to vent the captured fumes either directly to the atmosphere or depending on the working process, via a filtration unit.
