Avon EX750 CAT2 Barrier

Product overview

The EX750 CAT2 Barrier can operate in an area that is deemed to be a potentially explosive atmosphere. When dangerous substances combine with air, under atmospheric conditions and ignition has occurred, the combustion spreads to the entire unburned mixture.

How to reduce the risk of an explosion?

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.

• 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 & the IECEx standard.
