Explosion proof Air Blower.<\/p>\n

There are indeed two types of explosion-proof fans: gas explosion-proof and dust explosion-proof. There are essential differences between the two in terms of explosion-proof principles and applicable scenarios:<\/p>\n

Differences in explosion-proof types<\/p>\n

Gas explosion-proof blowers are mainly designed for combustible gas or steam environments, and use explosion-proof and safety enhancement technologies to prevent the danger caused by explosive gases. Dust explosion-proof fans are suitable for combustible dust environments, and can block dust explosion conditions through shell protection, surface temperature control, and other methods. \u200c<\/p>\n

Core design differences<\/p>\n

Gas Explosion proof: Typically designed with explosion-proof or increased safety features, the enclosure has a lower level of protection and may allow gas infiltration. \u200c<\/p>\n

Dust Explosion proof: The enclosure has a higher protection level (such as IP66) and is equipped with positive pressure, spark free and other technologies to prevent dust from entering or accumulating. \u200c<\/p>\n

\"\"Applicable scenario limitations<\/p>\n

Gas explosion-proof equipment cannot be used in dusty environments, and dust explosion-proof equipment is also not suitable for gas environments. For example, although the shell protection level of dust explosion-proof motors is high, they cannot prevent gas from entering, so the two cannot be used interchangeably.<\/p>\n

Gas explosion-proof is divided into CT4 and BT4<\/p>\n

CT4 and BT4 are two different explosion-proof standards in the gas explosion-proof level, with the main differences as follows:<\/p>\n

Difference in explosion-proof grade<\/p>\n

CT4: Explosion proof grade is ExdIICT4, suitable for environments with high-risk gases such as hydrogen and acetylene, with a maximum surface temperature not exceeding 135 \u2103. \u200c<\/p>\n

BT4: Explosion proof grade ExdIIBT4, suitable for conventional gases such as methane, petroleum gas, etc., with a maximum surface temperature not exceeding 135 \u2103. \u200c<\/p>\n

Applicable scenarios<\/p>\n

CT4: Suitable for areas with extremely hazardous gases such as acetylene and hydrogen (such as petrochemical and industrial gas processing). \u200c<\/p>\n

BT4: Suitable for conventional gas environments (such as methane, ethane, etc.), commonly found in ordinary industrial or commercial places.<\/p>","protected":false},"excerpt":{"rendered":"
