ATEX, derived from ‘ATmosphere EXplosible’ was extended from electrical equipment to cover mechanical equipment such as fans and came into force under Directive 94/9/EC on 01 July 2003.

The “zones” (according to RL 1999/92/EG) represent work areas in which an explosive atmosphere can occur. Depending on the frequency and the duration of the explosive atmosphere, ATEX defines different zones and corresponding categories:

  • Continuously or for longer periods of time. Zone 0 (=G) und 20 (=D) Equipment category 1
  • Occur occasionally. Zone 1 (=G) und 21 (=D) Equipment category (1 or) 2
  • Normally not likely to occur, or only for short periods of time. Zone 2 (=G) und 22 (=D) Equipment category (1, 2 or) 3
  • Only equipment, components and protective devices may be placed on the market which conform to the provisions of ATEX directive 94/9/EG.

We offer from the market leader, IVACO Srl’s range

The ATEX certification is recognised for zone 2-22:

II 3G Ex h IIB T4 Gc

II 3G Ex nA IIC T4 Gc

II 3D Ex tc IIIC T135 °C Dc IP65

IVACO Srl has designed and subjected all ATEX products to a rigorous ignition hazard assessment to determine correct design features (including a selection of compatible materials) and in conjunction with an authoritative standard.

All air blowers are subjected to a running test and some our fans are given an extended test run under closed damper conditions to verify & record maximum surface temperatures.

The actual features on our vacuum pumps and air blowers (eg. gas tight etc) will vary according to Zone, gas/dust type, ignition temperature and whether the zone is inside and/or out, open inlet or fully ducted. IVACO Srl has a range of ATEX fan grades to cover all eventualities which will be carefully selected by our experienced technical sales team. Please contact us to discuss this if you are unsure and we will guide you through your requirements. We will supply an ATEX questionnaire to assist you with this. Please note however that the determination of the actual zone has to be specified by the customer as this must be based on a site hazard assessment

We can offer customised solutions.
