what is the cfm rating at each speed?

I don't know the answer to that. I do know, however, that here in sw texas where it gets very hot, the unit does a poor job of cooling when the outside temp rises much above 95 degrees.

Where I work we regulate the psi at 90. As far as cfm goes I am not sure. My small 5hp 30 gal. compressor at home would not be able to keep up it with the compressor running the whole time.

Without Low Noise Adapter - 3000 RPM @ 17.2 CFMWith L.N.A - 2400 RPM @ 13.8 CFMWith U.L.N.A - 1600 RPM @ 9.83 CFM

Don't know the CFM, but these things have been running 24/7 at my local gym for at least the last four years. They are very robust -- industrial. Nothing like cheaper consumer fans.

This fan is three speed. I wrote to Lasko and here is what they said:CFM- 3160/LOW 3320/MED 3460/HIGHJust to reiterate what I and a lot of other reviewers have said: This fan puts out a ton of air and is pretty loud, especially on high. Construction is very solid. If you want to move a lot of air and you are okay with the noise it's hard to see how you could do much better.

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.

Search (Ctrl-F) for CFM. Under product description it says "Powerful 8-amp motor produces a strong 160 MPH air speed is produced at 160 CFM."

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.

Not sure about CFM. I have inflated a car tire with relatively low PSI (26 or so) up to 32 PSI in less than 60 seconds... perhaps less than 40 seconds.

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 Broan 4130 is not rated for CFM because it is a non ducted hood. Probably about 100-150 cfm fan, 2850 rpm. You don't want too much air blowing back in your face anyway. I hope this helps.

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

Sorry; I couldn't tell you CFM. However, in a small conference room (6 people), the fan at low speed produces a nice breeze on participants, but not enough to blow sheets of paper around. Same for the middle speed. The high speed will occasionally blow a piece of paper off the table. I hope that helps.

Specs claim this HVLP operates between 43-50#,and consumes 5.5-9.2 CFM perspectively. If you're using thin material on a small project, you might get by with minimum air delivery. I use a 6hp - 8.6 cfm. Sears 30gal compressor. The air delivery allows the use of all materials including slightly thick Latex paint. The flow in constant and consistent, plus I can fine tune a fan pattern with all the adjustment this inexpensive little gun has to offer. Don't blame your gun if you don't have the power to push it.

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 use it with an air compressor that puts out 17 to 25 cfm with no problem. If you need to use it non stop for long periods of time, a 2HP air compressor can not keep up.

Max Air Volume = 356 cfm and Max Air Speed = 145 mph. (This information is from the Makita website.) It blows very well and seems to actually work better than these numbers might suggest.
