防爆风机是一种专门设计用于存在易燃易爆气体或粉尘环境的通风设备，应用于石油化工、制药、电力、矿山、储能集装箱、锂离子电池、铅酸（炭）电池、液流电池、水电解制氢/燃料电池储能电站以及其他存在爆炸危险的行业中。这些风机经过特殊设计和制造，以确保它们在潜在爆炸性的环境中安全运行，不会因为内部或外部因素引发爆炸或火灾。
Explosion proof fan is a ventilation equipment specially designed for environments with flammable and explosive gases or dust. It is used in industries such as petrochemicals, pharmaceuticals, electricity, mining, energy storage containers, lithium-ion batteries, lead-acid (carbon) batteries, flow batteries, water electrolysis hydrogen /fuel cell energy storage power stations and other industries with explosion hazards. These fans are specially designed and manufactured to ensure their safe operation in potentially explosive environments, without causing explosions or fires due to internal or external factors.
其特点为：
Its characteristics are:
- 使用防爆电动机，以确保即使在极端情况下也不会成为火源。
Use explosion-proof motors to ensure that they will not become a source of fire even in extreme situations.
- 采用不易产生火花的金属材料，如铝合金，以及具有抗静电性能的塑料。
Use metal materials that do not easily generate sparks, such as aluminum alloy and plastics with anti-static properties.
- 结构上，风机外壳采用优质钢板焊接成型，叶片由铝合金铸造成形，表面进行喷塑处理，以增强耐腐蚀性。
In terms of structure, the fan housing is welded with high-quality steel plates and the blades are cast from aluminium alloy with its surface sprayed to enhance corrosion resistance.
- 可以选择壁式、管道式、岗位式、固定式等多种安装方式。
Multiple installation methods such as wall mounted, pipe mounted, post mounted and fixed can be selected.
在选购防爆风机时，要注意是否有防爆认证以及防爆标识，通常会标注在铭牌上。
（用具体风机铭牌说明）
When purchasing explosion-proof fans, attention should be paid to whether there is explosion-proof certification and explosion-proof labeling, which are usually marked on the nameplate.
标识符含义：
Identifier meaning:
六边形的EX，代表防爆产品的标志
The hexagonal EX represents the symbol of explosion-proof products
II表示非矿用环境下的气体
II represents gases in non-mining environments
3代表设备使用类别
3 represents the category of device usage
G代表气体环境
G represents gas environment
Ex e表示防爆类型增安型
Ex e represents explosion-proof type with increased safety
IIC表示设备可用气体环境中，属于最高等级。
IIC represents that the equipment can be used in a gas environment, belonging to the highest level.
Gc表示设备的一般等级保护，用于2区（即在正常运行时不太可能出现爆炸性气体混合物的环境，如果出现也只是偶尔短暂存在）。
Gc represents the general level protection of the device and is used for Zone 2 (i.e. an environment in which explosive gas mixtures are unlikely to occur during normal operation, and if it appears, it only exists occasionally and briefly)
防爆认证：
Explosion-proof certifications:
有IECEx，ATEX等。
There are IECEx, ATEX, etc.
