I got a 2hp 6 gallon air compressor with a max PSI of 125 PSI. I want to get a set of set of air tools. Most of them have an air rachet, impact wrench and air hammer.
I pretty sure it will run the rachet and impact but I don't know how well it will run the air hammer.
I have 3hp, 26 gallon tank and it has a hard time keeping up with my 1/2 inch air gun, i mean it works fine but the motor will be running quite often, specially with grinders and sanders etc. so most likely you'll have to get yourself a 26G or bigger tank. hope that helps
