Dust explosion-proof certification refers to the explosion-proof certification of explosion-proof equipment or products used in flammable and explosive dust areas. For example, various metal polishing, grain and oil facilities, plastic facilities, and other places.
Flammable and explosive dust areas can be classified into IIIA (combustible fly ash), IIIB (non-conductive dust), and IIIC (conductive dust) based on the nature of their hazardous substances. Customers can apply for appropriate explosion-proof marking levels according to their actual usage location.
