Can DC Fans Operate Effectively in High-Humidity Conditions?

[MisterX]

I want to design a device that will require a small dc fan that may have to operate for long periods with fog-like moisture passing through it. Is there any advice on what to look for?

Hella fans are designed for the marine environment. They last well.

My advice would be to take a step back from your design and try as hard as possible to design your system to not need that situation. Try to push fresh air if at all possible. If suction is absolutely necessary can a venturi ejector set up work? Can you use a heat gradient to make convection? Will compressed air help? Try your hardest to make electric devices + water not necessary.

Can you share more information?

Thank you but we need cost for the fan component a bit cheaper and also ideally not swiveled but just a block duct design like

or perhaps a DC blower.

It is a necessary part of the design.
