Explosion protection ratings are expressed in two standards, IP and EX. The IP standard is primarily concerned with protection ratings, while the EX standard specializes in explosion-protected equipment. In the EX standard, the next two digits represent the explosion protection class, for example, “d” in EXdIICT6 stands for explosion-proof enclosure, “II” stands for the type of gas or dust to which it applies, and “CT6” stands for the temperature rise limit. CT6” indicates the temperature rise limit.

At the same time, it is necessary to fully understand the environment and application requirements of the explosion-proof fan. Explosion-proof fans are mainly used in flammable and explosive environments, such as chemical plants, petrochemicals, coal mines and so on. When choosing an explosion-proof fan, you need to understand the environmental conditions in detail, including the grade of gas, liquid, dust, etc., temperature, humidity and other factors.

Finally, according to the specific environmental conditions and work requirements, to determine the appropriate explosion-proof level (such as Exd, Exe) and protection level (such as IP54, IP65). And, also consider the materials used for the fan, such as aluminum alloy, stainless steel, etc., as well as the corrosion resistance and high temperature resistance of these materials.
