Fire protection is not covered by ATEX guidelines
In contrast to explosion protection, fire protection is not clearly regulated by law.
This is why the operator should determine the extent of general or specific fire protection measures and the application of rules.

Fire protection in dust extraction installations
Whenever fire protection measures are requested by the operator or their insurer, Keller Lufttechnik always conforms to VDI guideline 2263-6 which specificially applies to dust extraction systems. Since there is no mandatory regulation regarding fire protection measures, the responsibility for fire protection lies with the operator. The applicable measures
can be determined in a hazard assessment according to the German Industrial Safety Regulation (BetrSichV).
Keller Lufttechnik can only suggest fire protection measures, but they are not mandatory for the operator.
Fire protection for dust collectorsBrochure
In the event of a fire, the ProBox ensures that flames from the machine tool are blocked from spreading throughout the ductwork. In addition, the flame barrier is equipped with a chip pre-separation device that ensures that no chips can enter the flame barrier / extraction system. This device improves the large air flow of the machine with a large detection surface, and coolants are pre-separated.
Optimized and safe machinery extraction
ProBox prevents the transfer of flames and the entry of ignition sources into the extraction system / centralized systems to other machinery (for processes using oil).
