Introducing the New PureFlo ESM+ Intrinsically Safe

A powered air purifying respirator (PAPR) for use in potentially explosive atmospheres

Gentex are pleased to announce the launch of the new PureFlo ESM+ Intrinsically Safe Powered Air Purifying Respirator. The ESM+ Intrinsically Safe respirator has been designed and manufactured by Gentex Europe to provide respiratory protection for personnel working in potentially explosive atmospheres.

The ESM+ Intrinsically Safe PAPR is an innovative all-in-one head mounted solution, providing head, eye, face and respiratory protection.

How is the product classed as intrinsically safe?

The equipment is certified as intrinsically safe for use in environments requiring equipment protection levels where Gas Group IIC or Dust Group IIIC is present.

Intrinsic safety is achieved by limiting the energy available from the battery packs and by limiting energy storage and discharge within the electronic and impeller assemblies.

The ESM+ is suitable for use in a range of industrial environments including heavy industrial/engineering, pharmaceutical and nuclear. Options are available with a hard hat or bump cap, with additional accessories e.g. welding shield or aluminised head top and cape for use in steel and smelting environments.

What is defined as an explosive atmosphere?

Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts.

Explosive atmospheres occur when flammable gases, mist, vapours or dust are mixed with air and an ignition source e.g. spark. This can then create the risk of an explosion. The amount of substance needed to create an explosive atmosphere will depend on the substance being used. The area where this possibility exists is therefore defined as an explosive atmosphere.

Where can explosive atmospheres be found?


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.

What approvals does the ESM+ Intrinsically Safe respirator meet?

The ESM+ Intrinsically Safe respirator is certified and meets the requirements of ATEX and IECEx.

Certification ensures that the equipment or protective system is fit for its intended purpose and that adequate information is supplied with it to ensure that it can be used safely.

What is ATEX?

ATEX is the name given to the European Workplace and Equipment Directives for controlling explosive atmospheres. The directives state the minimum requirements for improving health and safety protection for workers potentially at risk from explosive atmospheres.
