What should be paid attention to when customizing stainless steel corrosion-resistant Roots fans?

There are various types of Roots blowers, among which stainless steel Roots blowers are a very common one. This type of fan is commonly used in working conditions containing corrosive media, and generally uses 304 or 316 stainless steel as the material. What is the difference between the two?

316 stainless steel has added molybdenum compared to 304 stainless steel, thus improving its corrosion resistance and high-temperature strength, especially being more resistant to chloride corrosion. Therefore, the 316 stainless steel Roots blower can be applied to harsh environments containing chlorine such as seawater, chemicals, dyes, etc.

In addition, there are 304L and 316L stainless steels, which represent low-carbon and indicate low carbon content, making it less likely to produce chromium carbide. Therefore, the resistance to intergranular corrosion with L is better.

When customizing stainless steel corrosion-resistant Roots fans, the following points should be noted:

Consider the usage environment: It is necessary to consider the usage environment of the fan, whether it contains corrosive media such as seawater, chemicals, dyes, etc. This will affect the selection of stainless steel materials.

Material determination: There are various types of stainless steel materials, such as 304, 316, 304L, and 316L, and suitable materials need to be selected based on the usage environment and requirements.

Design parameters: It is necessary to determine parameters such as air volume and pressure of the fan, which will affect the efficiency, performance, and price of the fan.
