The shell of stainless steel roots blower is made of stainless steel, the structure is the same as that of ordinary roots blower, and it has the characteristics of high hardness, corrosion resistance, rust resistance and good thermal expansion coefficient. It is mostly used for conveying high temperature gas such as steam, and it is made of 304 stainless steel, 306 stainless steel, 301 stainless steel, 2205 stainless steel, etc., which has a wide range of uses, good quality and long service life.

       Stainless steel roots blowers are three blade linear impeller, intake and exhaust pulsation gentle, low noise. The whole machine has compact structure and beautiful appearance. Then let's talk about the difference between stainless steel roots blower and ordinary roots blower:

       1. Different corrosion resistance of stainless steel roots blower

       The roots blower made of stainless steel has strong corrosion resistance, such as carbon dioxide, hydrogen sulfide and chlorine when the transmission medium is acid gas. There are also alkaline gases such as ammonia. When conveying these gases, the roots blower must be made of stainless steel. It is not advisable to use the general cast iron roots blower.

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

       The roots blower used in the food industry requires that the output gas must be 100% clean, such as: sugar industry, milk powder industry. When the stainless steel roots blower is used, no micro particles will be discharged with the gas during the operation of the blower. However, when the cast iron roots blower is operated, more or less micro particles will be worn and mixed in the food after the gas is discharged. Therefore, the best choice for the food industry is stainless steel.

       3. Different price of stainless steel roots blower

       The cost of stainless steel roots blower is relatively high, and the products produced with expensive raw materials will naturally be expensive, which is three times higher than that of cast iron. Moreover, the production process of stainless steel is very difficult, because the material properties are very sticky. Combined with two factors, the price of stainless steel roots blower is at least several times higher than that of cast iron roots blower.

       4. Different hardness of stainless steel roots blower

       The hardness of stainless steel roots blower is higher, and the cast iron material is easier to process when it is processed.

       5. Thermal expansion coefficient of stainless steel roots blower

       When stainless steel roots blower is used for conveying steam, temperature is a factor that must be considered, because the thermal expansion coefficient of fans made of different materials is different, and the thermal expansion coefficient of fans made of cast iron and stainless steel is very different.
