ATEX 94/9/EC Directive became legally effective on 1 July 2003. It places responsibility on manufacturers of flameproof equipment to supply products that comply with specified ATEX classifications, as determined by the end-user. This now means that fans have to be designed to avoid the risk of electrical, electrostatic, thermal, and mechanical ignition hazards that may occur in specified flameproof Zones, Classifications and Gas Groups.
ATEX 99/92/EC Directive (ATEX 137) was also implemented on 1 July 2003. It became UK law on 1 July 2006 by the introduction of DSEAR (Dangerous Substances & Explosive Atmospheres Regulations), which must be observed by the end-user.
Axair Fans is capable of manufacturing plastic centrifugal fans to Equipment Category 3 (Zone 2) requirements by self-certification, and supplying metal fans in both centrifugal and axial construction to Equipment Category 2 (Zone 1).
