compressor for impact tool question(s)
 

Anyone out there that can tell me what the minimum requirements, (p.s.i., H.P., gallon size of tank), I need to run impact tools for home garage? I realize that bigger is better w/ these things, but I went on Harbor Freight site and the specs are all over the map. TIA. :cool:

90 to 120 PSI will be sufficient to run an air tool. The more horsepower, the better it will keep up with your tools. The larger the tank, the less often the compressor will have to run and cycle on and off.

For air tools like air ratchets and impact guns, you don't need anything fancy. It's when you start using die grinders, air sanders, and spray guns that you need a large tank, big power, and lots of flow.

Denis,

Take a look at this thread and this one also for more info than you would ever want to know on compressor selection.

Good luck,
Tim

I run a 15cfm twin piston compressor at between 40 psi and 110 psi at home. Like Tyson suggests, it's only when I'm running my spray gun that it runs regularly, it's not a problem for the compressor, just gets a bit noisy.
