A hazardous area or location could be any area that poses a risk of fire or explosion, due to a flammable or combustible liquid, dust or gas that is within the atmosphere or is being conveyed. This could include a fine powder, such as flour, which can be highly combustible, or a highly volatile gaseous compound such as methane or hydrogen gas. If electrical equipment is also being used, this makes the risk of fire or explosion even greater.
Explosion-proof fans can be found in almost any industry across the full range of industrial applications and are designed to not just fail to combust, but more specifically if the fan or blower does combust, it should be able to endure the explosion without any external cracks to the product.
As an industrial fan has a moving part (the impeller) and an electrical power supply (the motor), these products were specifically identified as a potential source of ignition, and today, there is a standard set of guidelines around the manufacture of fans being used in hazardous areas.
At present, we supplies industrial fans to Category 2G (Zone 1-gas), or 2D (Zone 21 – dust) and Category 3G (Zone 2-gas) or 3D (Zone 22-Dust).
The ATEX fans can be manufactured using Stainless Steel, Mild Steel, Aluminium and Plastic and our team of design engineers will select the right material depending on the substances present in the atmosphere.
All ATEX fans are thoroughly tested and assessed to make sure the design features meet all necessary requirements of the following standard: BS EN 14986:2017 Design of Fans working in potentially explosive atmospheres, BS EN ISO 80079-36:2016 & BS EN ISO 80079-37:2016 – Non-electrical equipment for use in explosive atmospheres.
