Acid and alkali resistant fan features:
耐酸碱风机特点：
1, acid and alkali fan has the characteristics of energy saving.
1、耐酸碱风机具有节能的特点。
Sealed bearing design can prevent acid and alkali gas intrusion, prevent bearings and shafts from being directly eroded by corrosive gases, and ensure the service life of bearings in operation.
密封轴承设计可防止酸碱气体侵入，防止轴承和轴被腐蚀性气体直接侵蚀，保证轴承在运行中的使用寿命。
2, the shell of the acid and alkali resistant fan is made of glass fiber reinforced resin (FRP) and is formed as a whole to avoid stress and improve strength.
2、耐酸碱风机的外壳由玻璃纤维增强树脂(FRP)制成，并整体成型，以避免应力并提高强度。
3. The shell of the acid and alkali resistant fan should be designed with a smooth surface to avoid attachment of impurities.
3、耐酸碱风机外壳应设计为表面光滑，避免杂质附着。
The mounting screws of the housing and inlet bell jar are pre-injected to avoid leakage.
壳体和入口钟形罩的装配螺钉是预注射的，以避免泄漏。
The installation method of the acid and alkali resistant fan housing must take into account future changes in the direction of the fan outlet.
耐酸碱风机外壳的安装方法必须考虑风机出口方向的未来变化。
4, acid and alkali fan has good acid and alkali resistance, can withstand hydrochloric acid, nitric acid, chromic acid and other highly corrosive gas corrosion.
4、耐酸碱风机具有良好的耐酸碱性能，能承受盐酸、硝酸、铬酸等高腐蚀性气体的腐蚀。
Its service life is 2-3 times that of plastic fans and carbon steel fans, and it is cost-effective.
它的使用寿命是塑料风扇和碳钢风扇的2-3倍，性价比高。
