Roots blower adopts three blade linear impeller, so the inlet and exhaust pulsation is slow and the noise is low. The whole machine has compact structure and beautiful appearance. Next, let's talk about the difference between stainless steel roots blower and ordinary roots blower:

1、不锈钢罗茨鼓风机的防腐能力不同

1. The corrosion resistance of stainless steel roots blower is different

由不锈钢制成的罗茨鼓风机防腐蚀能力强，如输送介质为酸性气体时，如二氧化碳、硫化氢、氯气还有氨气等碱性气体。输送这些气体时，罗茨风机需要采用不锈钢罗茨风机，不能使用一般的铸铁罗茨风机。

Roots blower made of stainless steel has strong anti-corrosion ability. For example, when the transmission medium is acidic gas, such as carbon dioxide, hydrogen sulfide, chlorine, ammonia and other alkaline gases. When conveying these gases, the roots blower needs to use stainless steel roots blower instead of ordinary cast iron roots blower.

2、不锈钢罗茨风机输出气体的清洁度不同

2. The cleanliness of output gas of stainless steel roots blower is different

食品行业使用的罗茨风机要求输出气体一定要清洁干净。例如，糖行业、奶粉行业。如果采用不锈钢材质的罗茨风机，在风机运转中，任何微粒都不会与气体一起排出，但在铸铁罗茨风机运转时，或多或少会产生微粒的磨损并与气体一起排出，混入食品中。因此，食品行业选择不锈钢材质。

The roots blower used in the food industry requires that the output gas must be clean. For example, sugar industry and milk powder industry. If the stainless steel roots blower is used, no particles will be discharged together with the gas during the operation of the blower. However, when the cast iron roots blower is operated, the particles will be more or less worn and discharged together with the gas and mixed into the food. Therefore, the food industry chooses stainless steel.

3、不锈钢罗茨风机的不同

3. The price of stainless steel roots blower is different

不锈钢罗茨鼓风机成本很高，原材料贵所以生产的产品自然就贵。一般要比铸铁贵三倍。另外，不锈钢材质属性很粘，因此制造过程的难度很高。综合两个因素，不锈钢罗茨风机的成品比铸铁罗茨风机少贵几倍。

The cost of stainless steel roots blower is very high, and the raw materials are expensive, so the products produced are naturally expensive. It is generally three times more expensive than cast iron. In addition, the properties of stainless steel are very sticky, so the manufacturing process is very difficult. Combining the two factors, the finished products of stainless steel roots blower are at least several times more expensive than cast iron roots blower.

4、不锈钢罗茨风机的硬度不同

4. The hardness of stainless steel roots blower is different

不锈钢罗茨风机硬度更高一些，铸铁材质更容易加工。

Stainless steel roots blower has higher hardness, and cast iron material is easier to process.

5、不锈钢罗茨风机的热膨胀系数

5. Thermal expansion coefficient of stainless steel roots blower

罗茨鼓风机在输送蒸汽时考虑温度的因素。由于鼓风机的热膨胀系数因材质而异，所以铸铁鼓风机和不锈钢鼓风机的热膨胀系数有很大差异。

The roots blower takes the temperature into consideration when delivering steam. Because the thermal expansion coefficient of the blower varies with the material, the thermal expansion coefficient of the cast iron blower and the stainless steel blower are very different.
