Wolong Nanyang Motor introduces the specific division standards for dust explosion proof motors to ensure safe operation in hazardous dust-filled environments. Dust explosion proof motor classification is based on the type frequency and concentration of combustible dust present during equipment operation. Understanding these standards helps with accurate electric motor selection and system design in industries with ignition risks.
Dust explosion proof motors are applied in areas classified as Zone 20 Zone 21 and Zone 22. Zone 20 refers to spaces where combustible dust is present continuously such as inside silos and enclosed conveyors. Zone 21 covers areas where dust may appear occasionally like processing equipment zones and bagging machines. Zone 22 includes spaces where dust presence is rare and only for short periods such as storage areas and maintenance zones.
Wolong Nanyang Motor designs dust explosion proof motors with flameproof housings temperature-limiting structures and anti-static features. Each electric motor is manufactured with sealed bearings reinforced insulation and corrosion-resistant coatings. The motors meet IEC and GB explosion protection requirements for industrial dust zones and are tested for thermal behavior and ignition prevention.
Dust explosion proof motor systems are used in flour mills grain elevators chemical processing plants and woodworking factories. Wolong Nanyang Motor offers energy saving motor solutions and high efficiency motor models for long-term safe use in harsh environments. Motor models are customizable for different voltage classes mounting types and load conditions.
Wolong Nanyang Motor continues to develop industrial motor technology to support dust hazard safety and global compliance across critical sectors.
