If you are going to be using a tool continuously, you need a larger tank than using a tool for shorter periods. I had a compressor with a two gallon tank that was fine for using my brad nailer. It could not keep up with using a rotary tool though. Sand blasters are huge air consumers.

And a sand blaster is probably the biggest consumer of air of all the air tools there are! Yes, you DO need a 10HP compressor to effectively sand blast with it. Bert

110 volt or 220 volt depends on what kind of power you have available. Standard household outlets are 110 volts and usually 20 or 30 amp breakers. Which means if you are using a standard outlet you will need a compressor that runs on 110 volts and 20 amps. CFM is cubic feet per minute. and PSI is Pound per Square Inch Most nail guns run on 90 PSI Other tools like Air impact wrenches and sanders can use up to 175 PSI but can usually be use with lower pressure they just wont be as powerful. The compressor you get depends on what you are doing and what kind of power you have where you will be using it. The higher your CFM is the faster your air tank will fill and the more air you can use constantly. The higher your PSI is the more power you will get out of your air tools(make sure not to exceed the max PSI for the tool). Also there is something called duty cycle. This is the percentage of the time that your compressor can be running. So if your duty cycle is 30 percent your compressor should only be running 3 minutes out of every ten. More than that can cause it to wear out too quickly. So make sure you are aware of the demand you will need and buy a compressor that is more than capable of keeping up. Hope this helped.

YOU HAVE HEARD CORRECTLY….THE AC MUST AT LEAST MEET THE CFM REQUIREMENTS OF THE TOOL…AND TO INSURE THE MAX USE OF THE TOOL MUST EXCEED THE CFM REQUIREMENT…
