I’m planning on getting a compressor to run small air tools, that I’ve had stored for years. Drills, die grinders, ratchet wrench, impact wrench, etc. I already have a portable compressor mounted on a tank, but the few times I tried to use it with an impact wrench, it wouldn’t work after fifteen seconds. I wasn’t surprised, but thought I’d give it a try.
Now I’m looking for a compressor that can be stationary, but most of all will do the job. I have three phase available, but would have to run a line to where I plan to install it, so that would add a cost.
What do I need as CFM output? Perhaps the most important part of the equation is the volume tank. I don’t like the idea of an inclosed unit. I would prefer the type with the motor separate with a belt driving the compressor.
The most reasonable prices seem to be complete units including the volume tank, that doesn’t seem big enough to me, at least compared to what I had used in shops years ago. Is getting one of these combination units and connecting it to an an additional big volume tank a good way to go? How many CFM is recommended? Or how many hp motor, which seems to be the only way many are rated, at least on the internet.
This is only for hobby type use or working on my car, not heavy everyday use. Therefore, I need to keep it economical or I won’t be able to afford to do it. Perhaps buying new battery powered tools would be less expensive in the long run. But I have always liked using air tools.
Thanks for all advice.
