Fan corrosion protection
Thread Content
The gas that is drawn in by my stainless steel fan contains salts, acids, *ao acids, sulfuric acid, toluene, xylene, methanol, and other substances; the temperature is around 40°C. During operation, it was found to have extremely high corrosivity. Are there any better anti-corrosion measures? Thank you all!
The anti-corrosion method using a lining could be considered
I’m not sure what the diameter of your fan is. Our company has just completed surface welding flaw detection and anti-corrosion coating treatment on the impeller of a phosphating fan with a diameter of 2.95 meters and an axis length of 4.5 meters. If you need it, you can add me on QQ; there are pictures there.
I’m wondering if the D470 can be used. What kind of spraying is this?

It is a tetrafluoro anti-corrosion coating that is resistant to corrosion, high temperatures, and friction. Apply an anti-corrosion coating to the surface of the equipment.
Fiberglass reinforced plastic fans and fans with PTFE linings can both be tried
Polymer ceramic coatings can solve the problem!
Hello, OP; this is a case involving complex operating conditions. Using a stainless steel fan is not a good idea. Fans made of plastic can effectively solve your problem, and the impellers also need to be made from special materials.
Since gas media are corrosive, it is best to replace them with corrosion-resistant fans; otherwise, both the impeller and the casing will get corroded. I am a manufacturer of special fans from Germany.
