Temperature: 300°C Flow rate: 6000 NM3/H Are there any debates regarding stainless steel impellers?

Choose it if you can afford it; it should be the high-end version. However, the medium in the boiler exhaust fan is not corrosive, so it’s not necessary to use it.

The medium drawn by the exhaust fan is corrosive. The impellers of our exhaust fans are showing significant corrosion.

For stainless steel impellers, the key factor is the application scenario!

Based on your temperature, a stainless steel impeller should be used; if it’s below 200 degrees, 16Mn will suffice.

304L with wear-resistant plate, or wear-resistant surfacing
