Does anyone know cfm (cubic feet per minute) for this model 4930?

Hard to get that information i guess the cfm should be a big number because i have never used it above speed 1. Huge amount of air... Very impressive.

I didn't find CFM rating anywhere. This is normally used for HVAC units and I don't know that it would apply to a vacuum. I can tell you that the suction is very strong and will pick up all kinds of shop dirt and dust. The blower is a little weak.

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.

Volume for this particular model is high, something like 120 cubic feet a minute. So, unless your design calls for that high a volume I'd keep on looking. Amazon had numerous capacity fans in their listings.

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.

i think the spec was 100 cfm, dont get the knock off model, it has half the volume pressure of the original manufacturers model sold on amazon for 20-30$ more

The box says between 29.2 cubic meters per hour and 16.7 m^3/h depending on what speed you run it at. The fastest speed converts to about 17 CFM. This is an amazingly well made fan.

Not sure, probably about 200 + cfm, I know it's strong enough to be felt 3/4 the way across my garage

The owners manual says 0.025 ft^3/cycle at 100psi, 0.023 ft^3/cycle at 90psi and 0.019 ft^3/cycle at 80psi. It also gives the following formula for cfm calculation, "Amount of air required = number of Nailers x average nails driven each minute per Nailer x air consumption at given pressure x safety factor (always 1.2)"

Yes. Something that closely matches the suggested rating (CFM and PSI). I bought a Husky Pro compressor on sale 3 years ago. It has a cast iron pump, 2 HP motor, 30 gallon tank and runs very quietly compared to other, smaller units I've owned/rented/borrowed. It can reach a maximum of 135psi and 6.5 CFM (cubic Feet per Minute) at 40 psi, 5.5 at 90 and does very well for my home projects (refinishing firearms, painting, among other things). If you got the sand blaster, I'd look into renting a compressor first until you know if you can justify the expense of investing in a larger compressor.

What Darren said is spot on. It should be fine. 75 RPM is only 7.5% (0.075) faster than the one you have now. If you still want another opinion, I would drop by the local technical college/school and find the HVAC instructor. Ask him or her to make sure. And it would be free advice, too.

From the manual. "AIR CONSUMPTION:The RN46 requires 3.9 cubic feet per minute (.11 cubic meters) of free air to operate at the rate of 100 nails per minute, at 80 p.s.i. (5.6 kg/cm). Take the actual rate at which the tool will be run to determine the amount of air required. For instance, if your fastener usage averages 50 nails per minute, you need 50% of the tool's c.f.m. which is required to operate the tool at 100 nails per minute."

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.

Take the cfm of the compressor at the pressure they give, at 100 psi they rate it at .94 cfm (cubic feet per minute) Take the container size of 2 gallons, convert to cubic feet ( 2 gal x .133 cu ft/gal = .266 cubic feet.)Now divide the cubic feet by cubic feet/per min and you have the time, roughly. ( .133/.266=.5 min or 30 seconds, theoretically) but, if you start with 0 psi the compressor pumps faster while the pressure is lower, so actual time should be less than 30 seconds for 2 gallons starting from zero. Hope this helps.

Approximately 12 inches high, 10 inches wide, and 4 inches deep. Moves 150 cubic ft per minute at 500 degrees f.

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.
