ATEX Gas Zone 1 + Dust Zone 21 (Category 2GD) covers industrial vacuum cleaners approved for environments where combustible gases and dusts may be present during normal operation. Category 2GD equipment provides strong external ignition protection for both gas and dust but is not certified for internal Zone 20, meaning it cannot collect combustible dust directly. Commonly used in pharmaceutical manufacturing, chemical processing, food production, maintenance operations and environments with moderate explosion risk.
