Description
ATEX DIRECTIVE : ATmosphere EXplosive 2GD / 3GD
APPLICATIONS
The axial fans manufactured according to the ATEX directive are suitable to extract air where flammable gas or dust mixtures are present. The temperature of the sucked fluids shall not be lower than -20°C and higher than +60°C, only for special applications can be obtained T. limits [-40 ° C; + 75 ° C]. These types of fans can be mounted in the pipelines of the plants, on the machines, on the walls or on the roofs of large environments like the industrial buildings. They are frequently used in various fields, such as in the chemical industry, in offshore platforms, in battery rooms, in the food and canning industry, in laboratories and so on.
SPECIAL CHARACTERISTICS
The fans of the ATEX series are mainly characterised by the materials used for their manufacture. These materials have been identified, tested and approved to minimize any explosion hazard according to the ATEX directive 2014/34/UE .
CONSTRUCTION TYPE
The standard execution foresees a conveyor made of carbon steel coated with epoxy paint. The impeller is made of plastic material type PAGAS (anti-static and anti-conductive material), with suction-side and delivery-side safety and accident-prevention net, manufactured according to the standards in force, and inspection door (only for the long casing executions). The special execution foresees a conveyor made of stainless steel AISI 304, wholly made of aluminum or made of carbon steel with aluminum band in the passage area of the wheel. Impeller can be made of aluminum when the fan is provided with non-ferrous material conveyor according to pairings allowed by current standards. All the components are assembled to the electric motor, from B3 or B5, ATEX type-approved (explosion-proof or with higher security level), according to the explosive atmosphere required.
