What is the CFM for this fan?

It varies depending on how much sun you have. It worked very well for me in a compact attic You may need two if you have big attic.

the fan operates at 200cfm at high speed with a mouth of 4"diameter. You may use any filter but suction may reduce on type. This is a trial and error depending on your need.

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.

19" As per my servery, this fan is the best among others in motor capacity and in speed(cfm)Good luck

I'm sorry but I'm really not sure. It's been awhile since the fan was installed. Your best bet is to check with the manufacturer.

Not sure about CFM's but it runs @ 1700rpm on high & 1200rpm on medium. Moves a pretty good amount of air on high & will last about 1hr 45min on that setting with a fresh charged 18v 3amh battery.

I have neither tested the ouput pressure of this fan in Pascals (Pa), nor in inches of water or inches of Hg. I would say that this fan is quieter than some fans that I have used that have axial flow and 400 CFM capacity (that would be nearly zero pressure drop to get that 400 CFM, by the way), and I use it to push air from near the floor of my greenhouse toward the gable of said greenhouse, mixing the air to reduce the thermal gradient and to give the plants air circulation, drying off their leaves from automated misting.

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!

The reason I replaced by 20 year old fans was poor performance and/or extreme noise. These were definitely an improvement, but I cannot say I can detect the higher CFM performance. Easy to install though.

My motor/fan assembly is mounted on a Nutone Scovill 696N-B unit which has a cfm rating of 50 at .10 wg. Your results will vary depending on the unit in which it's mounted.

~7 cfm @ 40PSI. Real world working performance hasn't given me any indication to think otherwise.

Wish I could help but I do not know what the difference is. Sorry!!! What is the make and model number of your fan?

The fan does not indicate cfm rating on it. I can tell you that I have two of these...each is on a 500 watt carver amplifier and they always stay cool! And the fans are extremely quiet also....an important consideration in my listening room.

I would say around 27 to 28 inches best fan I ever owned I mean I just use it on low. its a awsome built fan. C.

I don't the exact conversion for cfm, but the specifications are on their site here: http://noctua.at/main.php?show=productview&products;_id=48&lng;=en&set;=1It will obviously depend on the speed that you drive the fan. I can tell you this is the best 60mm fan I have ever come across.

I don't see a wattage rating on the fan. It's as strong as any other fan I've used in this size. I run it about 3 feet behind me and it moves plenty of air on low setting.

I have the dual fans (4000 cfm) ... using to cool a 355 SBC they are quality units, work fine, however, they draw a lot of juice and are noise.I had to go to a 140 amp. alternator to carry the load. I'm going to put seperateswitches so I can run 1 fan on cool days and 2 only when needed to drop the loadand noise. engine mounted in a '74 260Z roadster conversion with tight engine bayso cooling, even with an alum. rad. and ceramic coated headers a task. Fans did the trick.
