Explosion-proof blowers

Both the gas or gas mixture to be transported and the ambient atmosphere inside and outside the production plant may be explosive and thus extremely dangerous. No matter whether the risk of explosion is temporary, long-term or constant, the safety of your production line and, above all, your employees take first priority. Explosions must therefore be prevented and the risk excluded as far as possible.

Nevertheless, in the event of the gas mixture igniting it must be ensured that the explosion is confined to the machine and damage to the plant and personal injury prevented. We ensure greater safety with our explosion-proof blowers and their tested components from well-known manufacturers. In application areas like Zone 21 or 22 through to the most dangerous Zone 0 applications, in which the risk of explosion is permanent, we are your competent partner.
