What are the differences between fiberglass blades and aluminum alloy blades used for air cooler fans?
Thread Content
What types of media or operating conditions require that fiberglass-reinforced plastic blades or aluminum alloy blades be used exclusively? O(∩_∩)O Thank you
It seems that for explosion-proof motors, only aluminum alloy can be used
Bro, where did you see that claim?
Materials such as fiberglass do not conduct electricity; when the fan rotates rapidly, friction should occur (friction generates electricity). By using impellers that do not conduct electricity, static electricity cannot be transmitted to the ground. You can consult some manufacturers that produce fans; they are quite professional
Okay, O(∩_∩)O thank you
