Dust explosion-proof certification is for explosion-proof equipment and products used in flammable and explosive dust atmospheres, such as metal grinding, grain and oil processing, plastic manufacturing and other workplaces.
Flammable and explosive dust atmospheres are classified by the nature of their hazardous substances into IIIA (flammable flyings), IIIB (non-conductive dust) and IIIC (conductive dust). Clients can apply for the appropriate Ex marking rating based on their actual application workplaces.
