What is the CFM rating of this fan?

it's one of the funny things, they don't list it they just list the square footage.

I couldn't find the answer to your question. I even searched the manufacturer's website. Although I purchased it anyhow, (actually two), and installed them a couple of months ago I am pleased with my purchase. They are quiet, you really can hardly hear them running at all. One thing they don't mention in the ad is it also depends on what the pitch of your roof is. The wider the angle the less flow you will get. So the steeper, (sharper), your angle you will need only one fan because all the heat is concentrated more at the peak. This is why I purchased two I have more of a standard pitch roof. For the price I think they are a good purchase. I couldn't find the answer to your question. I even searched the manufacturer's website.

The honeywell site will tell you the theoretical cfm, I don't recall what they claimed. The actual horsepower will depend on time of day, season and solar cell positioning. I purchased a larger solar cell to get more air moving in the winter months as it was pretty anemic. Still, a worthwhile purchase and it is working solid after 6 months.

Ventilates roof area up to 1250 sq.ft. Motor is 24 volts solar panel is 12 Watts. Have no specs on CFM. Contact customer service 1-800-459-4409. I guess since we are using the solar rays it varies to much and will not give us a constant cfm rating. More sun the faster it goes, less sun slower it goes. Go for it. You will won't regret it.

Dave, I'm not an engineer, so I don't speak the eng jargon. That said, The spec indicates 2200 CFM. That's in a test situation. If you plan to use the fan in a vehicle, CFM through the fan will depend on how well you seal the attaching ducting. Your real consideration would be through the radiator, however. They don't give wattage or amp draw in specs, too bad. You would have to contact the mfgr for that. I would guess five amps, but that's just a guess. I have mine fused at 15 amps. No problems yet. RE: your static pressures question, you could extrapolate from assumed 2200 at sea level and probably get pretty close.

CFM rating for 14 inch air king Fan varies from 1180 to 1650 CFM , HP is 1/20th, Motor bearing is Ball Bearing--permanently lubed, The fan can be called quiet on first speed, but becomes intrusive on 2nd and 3rd speed. It is a very good product in my book by any measure

Do bear in mind that the rated 52 CFM is at the best possible scenario, where nothing is blocking the fan in front and/or behind it. Once you have a filter, it'll reduce that 52 CFM. Also, in my opinion, I don't think these fans are overly quiet.

Don't know the cfm but this thing works like a champ! Set it and forget it! It does come with a fan.

It's pretty loud. Manufacture specs say 50dB, I'd say that just about right. It's about the same noise as one of the old box style fans.

I don't know. All I know is that it's an excellent fan for me here in the U.S. Sorry I can't be of more help!

You need atlest 5 CFM at 90psi you can have lower then 5 but doesn't perform at full potential.

It is an 80 CFM fan and is outstanding. Very quite and powerful. My bathroom rated a 50 CFM fan but I wanted to make sure to clear out the steam and this fan does just that. Very happy with purchase.

I'm sorry, I don't. It may be on the specs at the bottom of the page on the info page for the fan.

While I can not answer directly, this is a powerful, quiet well made fan. I'm in Hawaii and this fan has been in almost constant use for 9 months. I continue to be very satisfied in every regard.

According to the product description for this same fan over at Sears.com, it's pushing 179 CFM.Power requirements are needlessly hard to come by. Hengs Industries doesn't even list it on their site.

It lists as 12.5 but I have since put an additional 45 CFM computer fan next to it and the Valterra fan blows almost 3 times as hard as the comp fan. I think they got the measurement wrong.

The 80mm fan (which I bought) is rated at 10.9-40.3 CFM on the box, and 13-28 dBA. Those seem believable.

I have an 8" fan and it works fine. I'd have to check the maximum air movement, but I'm almost sure it exceeds 265 cfm.
