ATEX

What is ATEX?

ATEX 94/9/EC is the directive on equipment and protective systems intended for use in potentially explosive atmospheres.

Can you certify fans?

Yes, Halifax Fan has been producing fans to the ATEX requirements for Group II equipment with gas and dust hazards for some time now and is one of the leading manufacturers in Europe.

Is ATEX a legal requirement?

As of  the 1 July 2003. The directive is now EU law and any equipment, electrical or mechanical for installation within the EU member states must now comply.

Where do I start?

ATEX is not only applicable to fans. Users of ATEX fans should also be aware of the implications in respect of their own installations. Our technical paper “Implications for Manufacturers” which was presented to the Institute of Mechanical Engineers in 2003 includes important information for fan users.

As part of the ATEX Directive we have a duty to liaise with our customers and obtain particular information to enable us to select fans of the correct category and certification to satisfy application requirements. To assist you with your enquiries and to help us formulate an appropriate proposal, we offer our “ATEX Fan Enquiry Form” for completion and submission. Although this form is not mandatory, it is offered as an ‘aide memoir’ and as a basis to discuss and agree your requirements.
