There seems to be a LOT of misinformation about this tool and air compressors in general. I compiled a list of quotes on another thread of MANY people that have this tool and how they worked around the CFM requirements. Im going to try my best to explain a few things and help some people out.
There are different variables with this set up and they all are not constant. You have PSI. The tool requires 90PSI to operate. Not more, not less. No problem. Most compressors, even pancake ones have a 125 or higher PSI rating. The tool consumes 9.3 (I think) cubic feet of air per minute. For this purpose lets just say 9.3. So what does that mean? That means that if I stand there with the tornador black and just hold the trigger forever that it will use up 9.3 cubic feet of air every minute while blowing 90psi. If I have a 9.3 cubic foot tank it will take one minute before I lose that 90psi and I have to let the tank refill. If I have a compressor that is only rated at 4.5 cfm at 90 psi (the tank is still 9.3) that means it will only blow 90psi for 30 seconds before the compressor kicks back on and I have to refill. So what if I have a 4.5cfm at 90psi compressor with a 10 gallon tank? well Ill get a few minutes or more of sustained pressure before Im empty and the tanks has to refill. Again thats if Im just holding the trigger down forever. The tool still works.
Having a compressor that blows 90psi at 10cfm means basically that I can stand there till the end of time holding the trigger and I will never lose power or have down time while using this tool. The compressor will kick on every now and then depending on the size of the tank but I will NOT lose power.
We dont use this tool "always on" so while you are wiping or whatever the compressor will be refilling your tank. You can get a compressor with at LEAST a 10 gal tank and have a rating of 4.5 CFM and you will be able to use this tool the way its intended just fine.
