ATEX Zone 22 – internal Zone 20 (Category 1/3D) includes industrial vacuum cleaners approved for use in Zone 22 while also featuring internal Zone 20 (Da) protection for direct recovery of combustible dust. This combination allows the equipment to operate in environments where external dust presence is occasional, but internal ignition protection must be at the highest level. Compliant with ATEX Directive 2014/34/EU and EN 17348, commonly used in food processing, metalworking and general dust-handling industries.
