In our main bath we have a Panasonic rated as 2.0. This one is significantly more noisy. Not sure about the air flow rate but the sound of 2.5 sones seems more appropriate.

As far as I know this is 1.5 sones. I have this installed in my daughter's bathroom it is pretty quite. The 2.5 sones is pretty loud compared to the 1.5 sones.

I think it is 1.5 sones. We purchased 3 within one year and all were very quiet.

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

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.

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

not sure about cfm but I believe its rated at 90 psi run mine in a commercial garage with 150 psi every day wouldn't recommend for concrete busting sounds more like a job for a jack hammer use the right tool for the right job & you'll never have a problem

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.

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.

There are 2 fan sizes - this one, which is for the large and XL is 25 CFM which is the larger of the two fans. The other is 10 - this one is for the small or medium egg.

NuTone's website indictes 2.0 sones. You could also check there to see if you can compare the dimensions. I didn't use it to replace another fan so don't know. Good luck

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.

On high, it's 2500 CFM. Even on low, I find it's very powerful and cools the room more than adequately. However, it is noisy.

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.

Dont know the CFM, but the fan is fairly quiet. Keeps the master bedroom ventilated at night without keeping me awake. Sorry not more details.

CFM, this term designates cubic feet per minute, 375 CFM means that every minute 375 cubic feet of air volume is pushed through the end of the nozzle. Second is MPH, this designates the speed in which the air excapes the end of the nozzle. not sure why you need to know this? BUT, you should see your answer in the manual that came with the Window/wall fans - and if not the manuf. will give this to you. The one I have is awesome been working daily since purchased 2 yrs ago and gives ample air flow in and out to cool down the room: pushes the cool air from one room to the other - I didn't put it in outside window - its in the house. But would work just as nice in outside window.

My inline Panasonic 30NLF1 exhaust fan is extremely low noise. I have to strain to hear it. I should have added a small light to show when it is on.Buy the highest CFM you can afford.
