Product overview

The Avon EB750 ATEX CAT3 Barrier can operate in an area that is deemed to be a potentially explosive atmosphere, an explosive atmosphere can be caused by flammable gases, mists or vapours or by combustible dusts. When these dangerous substances combine with air, under atmospheric conditions and ignition has occurred, the combustion spreads to the entire unburned mixture.

Many workplaces may contain, or have activities that produce, explosive or potentially explosive atmospheres. Examples include places where work activities create or release flammable gases or vapours, such as vehicle paint spraying, or in workplaces handling fine organic dusts such as grain flour or wood.

How to reduce the risk of an explosion?

  • Prevention & reduction of the amount of dangerous substances that cause the explosive atmostphere.
  • Prevent ignition source

Mechanical & electrical equipment that operate in zoned areas should comply with the requirement of the ATEX directive.
