Mechatronics ATEX Fan Solutions
Mechatronics offers a variety of fans for use in potentially hazardous applications and environments. ATEX Fans are intended for use in equipment or protective systems where potentially explosive atmospheres can occur (as defined by EU directive 2014/34/EU). Mechatronics ATEX Fans are EC Fans (electronically commutated AC fans) made with encapsulated motors rated to IP68. ATEX Rating levels for Mechatronics fans are listed in the table below. Only fans with the ATEX symbol and rating on the label are intended for ATEX applications.

What is ATEX and where are ATEX rated fans used?
Special electric components are required for environments where explosive gasses, vapor-air mixture, or combustible dust is possible in concentrations high enough to cause explosions. ATEX directives were adopted to align the technical requirements for products intended for use in potentially explosive atmospheres. Mechatronics ATEX rated products comply with the directives. All Mechatronics ATEX rated fans are marked with ATEX symbols and markings that indicate protection level and conformity with the directive. The ATEX directives not only define product requirements, but also classify environment zones and equipment categories. For more information on ATEX Directives, Ratings, and certifications visit the European Commission website for ATEX.
What is an EC Fan and why is it used in applications requiring ATEX?
Mechatronics electronically commutated (EC) technology fans converts AC power to DC power internal to the fan, so Mechatronics EC fans can be installed anywhere a similar sized AC fan is used. Energy saving EC fan technology is used to make ATEX fans because the design allows for coating or complete encapsulation of internal electrical components connections and the fan motor winding. Mechatronics UL recognized EC fans with ATEX rating are available in frame sizes from 60mm-172mm, with models compatible with input voltages from 100-240VAC. Mechatronics EC fans come standard with terminal type plugs or lead wires for simple replacement of less efficient AC fans in existing applications.
What is Encapsulation, and why choose this type of ATEX fan?
Encapsulation is the process of injection molding an epoxy compound that completely fills all cavities around the entire PCB and motor assembly before installation of the bearings, shaft assembly, and impeller. Encapsulation is a superior method of environmental protection for ATEX applications because it is designed to completely prevent water or dust contact with the fans electrical components and motor assembly. Mechatronics 2nd generation encapsulated fans have been third party tested to both dust and water standards for ingress protection, to IP68.
