Yes it can be. The 10ft cord will aleviate the issue of reaching an outlet if one is up the wall a ways in the upstairs room
Yes, that's what I did. It did take some modification the metal vent The outside edge) needs to be cut a little to make room for the cord. Not a big deal if you are handy.
Up to 200 square feet.
Sorry you cannot add a switch. Any modification to the fan would also void the warranty.
The fan motor turns the blades only one way. But you can position the fan upon installation to move air in your preferred direction. If you wanted to change directions on-the-fly, you would have to install the fan so that you could physically pull it out of the wall and turn it the other way 'round, or you could install two of these fans - one for each direction!
I think it would work just fine for that. I had a sleeping loft built in my den and I put one of these in there so it was well ventilated for the guest sleeping there (or my daughter,who loves it!)
The delivery was shorter than expected and had it installed within 1 hours works great
Low noise level. Not super quiet but very quiet.
yes you can see through the fan, not a good view since you are looking through the blades
