防爆風機是一種專門設計用于存在易燃易爆氣體或粉塵環境的通風設備，應用于石油化工、制藥、電力、礦山、儲能集裝箱、鋰離子電池、鉛酸（炭）電池、液流電池、水電解制氫/燃料電池儲能電站以及其他存在爆炸危險的行業中。這些風機經過特殊設計和制造，以確保它們在潛在爆炸性的環境中安全運行，不會因為內部或外部因素引發爆炸或火災。
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.
其特點為：
Its characteristics are:
- 使用防爆電動機，以確保即使在極端情況下也不會成為火源。
Use explosion-proof motors to ensure that they will not become a source of fire even in extreme situations.
- 采用不易產生火花的金屬材料，如鋁合金，以及具有抗靜電性能的塑料。
Use metal materials that do not easily generate sparks, such as aluminum alloy and plastics with anti-static properties.
- 結構上，風機外殼采用優質鋼板焊接成型，葉片由鋁合金鑄造成形，表面進行噴塑處理，以增強耐腐蝕性。
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.
- 可以選擇壁式、管道式、崗位式、固定式等多種安裝方式。
Multiple installation methods such as wall mounted, pipe mounted, post mounted and fixed can be selected.
在選購防爆風機時，要注意是否有防爆認證以及防爆標識，通常會標注在銘牌上。
（用具體風機銘牌說明）
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.
標識符含義：
Identifier meaning:
六邊形的EX，代表防爆產品的標志
The hexagonal EX represents the symbol of explosion-proof products
II表示非礦用環境下的氣體
II represents gases in non-mining environments
3代表設備使用類別
3 represents the category of device usage
G代表氣體環境
G represents gas environment
Ex e表示防爆類型增安型
Ex e represents explosion-proof type with increased safety
IIC表示設備可用氣體環境中，屬于最高等級。
IIC represents that the equipment can be used in a gas environment, belonging to the highest level.
Gc表示設備的一般等級保護，用于2區（即在正常運行時不太可能出現爆炸性氣體混合物的環境，如果出現也只是偶爾短暫存在）。
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)
防爆認證：
Explosion-proof certifications:
有IECEx，ATEX等。
There are IECEx, ATEX, etc.
