Explosion-proof respiratory protection is more than just a mask
Situations where respiratory protection with an electric powered air system is used are becoming increasingly common. But what if the workspace is an ATEX zone, meaning an environment with an explosive mixture of air, gas, vapor, or dust? Then you need explosion-proof respiratory protection. We explain why choosing an ATEX-approved powered air system from Sundström is your best option.
100% Intrinsically Explosion-Proof
Sundström’s vision is to use different products to create a complete system—not only for regular respiratory protection but especially for explosion-proof protection. It is essential that the system is 100% intrinsically explosion-proof. For the SR 500 EX powered air system from Sundström, this means that the electrical components in the unit are insulated in such a way that spark formation is completely prevented. Other powered air systems require modifications first, such as covering the unit with a protective cover—a rather vulnerable method that is much less reliable than an intrinsically safe system.
ATEX Certified as a Complete System
For many explosion-proof respiratory protection products available on the market, only the motor unit has ATEX approval. When you connect a mask or face shield to it, you expand the system and must also consider the potential ignition energy of these components. Sundström is unique in providing each facepiece with its own ATEX approval. The SR 500 EX system is therefore certified as a complete system, giving you the guarantee that you are working explosion-proof at all times.
