All applicable ACI fans have been certified by SRA, a long established UKAS accredited independent certification service (please visit www.sraservicescom for more details.) Customers wishingto order fansthat are expected to operate in these explosive/hazardous areas should contact ACI and discuss their requirements.

ATEX fans can be manufactured from stainless steel, galvanised steel or aluminium. Consideration must be gven to any aggessive substance in the atmosphere with regard to the material used in the manufacture. Fore marine applications, special paint finishes are also available.

Category M1 (Very high level of protection)

The equipment is intended for use in mines endangered by firedamp (an explosive gas when mixed with air in certain proportions) and is required to remain functional in the presence of an explosive

atmosphere._

Category 2 (High level of protection)

The equipment is intended for use in mines endangered by firedamp but is de-energsed in the event of an explosive atmosphere.

Group I

Underground work in mines and parts of their surface installations

Category 1 (Very high level of protection)

Areas in which explosve atmospheres caused by mixtures of air and gases, vapours or mists by air/dust mixtures are present continuously, for long periods or frequently. In this are no electric motors can be installed._

Group II

Environment in which gases, vapours, mists or dusts are likely to occur, which! together with air may form a potentially explosive atmosphere
