Question: Model 630B- what are the dimensions?
Document: Anyway, last year I wanted to buy another, and lo and behold, they don't make them this way anymore. I bought one anyway, even though it only had  a 3-speed (click-click-click) knob, and at the lowest speed it's quite noisy. And though I'm not entirely sure that this model, the Vornado 630B, is the one I tried, I think it is, and it's noisy. Upshot: I don't think there IS a quiet fan made by anyone anywhere anymore.
So as far as brand value and quality, you can't get much better.This specific 630B 3-speed fan is one of their mid-size models. It sits firmly on the floor with a large base, and the control knob is conveniently located on the side of base to fan arm.
I bought the 630B over the 530 thinking it will be bigger, but it is not as big as I imagined. However, it is very effective. It does have a very strong and consistent flow of air even at the lowest setting and does a nice job of circulating the air for a decent size room - 10x15. It's not that noisy either, but I am just using this at the lowest setting.
We previously bought another Vornado higher end model for $30 more. That works great also and has more speed settings. This has three speeds and the base is stable.
Not only is it much quieter than the terrible fan I purchased from KMART (which broke after one hour of use), it produces a refreshing breeze that can be felt from an entire room away! I currently use the 630B Whole Room Air Circulator to augment the power of my window unit A/C, a task it has performed admirably for over a month now.
I sleep with a fan for the white noise, and because I like some wind on me as well. Most fans I purchase tend to rattle, either right away or after a few months.The Vornado 630B so far feels very solid. There is no rattling, but perhaps it is too early to tell if it will eventually rattle.The white noise (actually more like brown noise) with this fan is perfect for me when it is on high.
I now own two of this same model and I highly recommend this. They have a fairly small foot print, they are very quiet on the lower setting. When you bump the speed up it does get louder but I don't find it obnoxiously loud.This really circulates a lot of air.
I purchased two of these air circulators after reading the reviews. They arrived yesterday, we plugged one in, turned it on, and were literally, pardon the pun, blown away at how incredibly well it works. The Vornado 630B has power, versatility and it's relatively quiet. You do not need to turn up the volume on your television or turn it down if you get a phone call. I wish I had known about this wonderful item sooner.
I bought my Vornado 630B 3-speed fan about a year ago. It is a very quiet, seemingly well built fan. However, for the money, I was not overly impressed with the volume of air that it moves. It moves no more air than you would expect from even the cheapest of fans (but does so very quietly). So, if you want it for its quietness, 5-stars... for volume of air, I would buy a cheap fan.
I do not have AC and was looking for a fan that circulated air better than the standard fan. After testing out a few models, I found that this model of the Vornado produced a noticeably cooler room. I like the slowest speed in that it is very quiet and hardly noticeable.
