ATEX Fans – Safe Operation in Explosive Atmospheres

ATEX refers to the European directives governing equipment intended for use in potentially explosive atmospheres. ATEX fans are specifically designed to operate safely where flammable gases, vapours, mists or combustible dusts may be present. Selecting the correct ATEX-rated fan is critical and must be based not only on the characteristics of the media being conveyed, but also on the classification of the external environment in which the fan is installed. Proper specification ensures compliance, minimises ignition risk, and safeguards personnel, plant and processes.

Our ATEX Fan Capabilities

Fan Systems, as part of the Witt Group, manufactures ATEX-certified fans for Gas Zones 0, 1 and 2 (Categories 1G, 2G and 3G) and Dust Zones 21 and 22 (Categories 2D and 3D). All ATEX fans are designed and manufactured in accordance with BS EN 14986:2024 – Design of fans working in potentially explosive atmospheres, BS EN ISO 80079-36:2016 – for non-electrical equipment for explosive atmospheres (basic method and requirements),BS EN ISO 80079-37:2016 – for non-electrical equipment for explosive atmospheres.
Our solutions are engineered to meet the required protection category and zone classification, ensuring safe, compliant and reliable performance across a wide range of industrial applications.

The Explosion-proof fans are made from normal steel, stainless steel, nickel-based alloys or special coatings (Halar®), e.g. for use in chemical, petro¬chemical and pharmaceutical plants. These fans can produce volumes up to 5,000m3/h, pressures of up to 34,000Pa and are certified by PTB / INERIS. Fans are constructed to withstand an internal explosion of design pressure up to 10 bar. Additionally, flame arrestors are fitted to both sides of the fan, which are tested and certified in accordance with the latest European rules and bear the ATEX-certificate 94/9/EC. These arrestors protect the upstream and downstream installation against fire hazards. Please contact us for further information on this range.
