Input:
I bought this for my kitchen window. I needed a fan to use vertical in it. It fits my 37" opening with no problems. I have one fan on exhaust and the other on intake. It helps keep the kitchen about 5 degrees cooler now according to inside temperature. It rather quiet, not extremely quiet but it's a fan so its what you expect but nothing to loud I can't hear the radio on low volume.
