Explosion-proof blower applies to the places where inflammable and explosive gas exists or the environment

 

Naxide explosion-proof high-pressure blower for signs: EX d Ⅱ T4 GB B, the following for explosion-proof interpretation signs:

Is the EX explosion-proof products

Explosive-proof grade classification, the former are Ⅱ domestic explosion-proof level for class, do not have the ability to develop Ⅰ class

Ⅰ class: the coal mine electrical equipment; (mine)

Ⅱ class: in addition to underground coal mines, all of the other electrical equipments used in explosive gas environment. (factory)

Ⅱ class and can be divided into A and B Ⅱ Ⅱ Ⅱ class C, sign Ⅱ B equipment can be applied to Ⅱ used conditions of equipment; Ⅱ C can be applied to the use of A and B Ⅱ Ⅱ conditions.

Temperature classes, the equipment surface temperature is lower, the better
