Hazardous-area qualification

The reviewed product family is labelled for ATEX Zone 22. That label alone does not determine suitability for every combustible dust or installation.

Classify the dust and workplace zone before equipment selection.
Check the exact model documentation, marking, temperature class and installation conditions.
Provide conductive ducting, bonding and grounding where required by the site design.
Confirm the dust container and filter-cleaning procedure do not create an uncontrolled ignition or exposure risk.
Have the complete extraction system reviewed against applicable local hazardous-area and occupational-safety requirements.
