DC fan for humid environment

  1. Jul 11, 2016 #1
    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?

    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?

    It is a necessary part of the design.

    When you ask a question but withhold critical information, you waste our time. That's not nice. If you want more help, please give us the complete list of requirements.
