Is there some sort of fan that is designed to run 24/7 and is well
protected against overheating?

I read of household fans being a fire hazard long time ago. Only reason
I remember is because my hubby likes to leave them running, 24/7, even
when the room is not occupied.

If you are planning a permanent installation, then find a fan built for
the purpose that runs on a timer. Constant circ. seems a waste

It's not just a waste of electricity and fan-life. It makes the room
warmer. It's only of value when a breeze is blowing on a person and
probably some animals.

- just
periodic to sufficiently move the air. Is the crawl space sealed up
with moisture barrier?
