    Default Recommended Air Compressor for ATC

    Hello All -

    Can anyone recommend a good compressor for the ATC? ShoBot is spec'ing:

    7 SCFM at 100PSI of clean, dry, un-oiled compressed air at a minimum with tubing no smaller than 3/8" throughout the system (1/2” recommended).

    but I am having a hard time finding one that matches these requirements.

    Thank you!

    I bought a Home Depot 60 gallon compressor and it works fine. I had a 30 gallon and it was to small. I do have 1/2" line running from the compressor to the CNC. All my other tools run off 3/8" hose just fine.

    hey thanks Dan!

    The thing that is holding me up is the 7 SCFM at 100PSI of clean, dry, un-oiled compresse notation - did you match these specs or are you running something different?

    I matched them up and the compressor exceeded what the ATC needs. I've been running for about 5 months with no problems. My cycle rate on the compressor, when running the CNC, is 4 minutes shut off, 1.5 minutes recharge. I do have a couple of small leaks in my air line I have to fix near the compressor, but I'm happy with the cycle rate. The ATC comes with the moisture separator, plus I have a moisture separator mounted on the compressor.

    I've been able to run a Kreg air pocket whole machine along with power tools (not sanders) along with my pneumatic assembly table with no problems running the compressor out of air. Mine is 220v.

    https://www.mcmaster.com/oil-separators/ not the only source just a place to start. It's recommended (and good for all air tools) to have one down the line (far enough away form the compressor so the compressed air has a chance to cool down and the moisture to condensate) at a low point in the line.
