I am looking at buying a Kaeser 15hp (SK15 with drier and large-ish tank) screw compressor that is available for a good price used. I believe it is rated for around 70 CFM. Right now I only have one 5-axis cnc mill that needs about 10 CFM and a small manual CMM. In the future I’ll have more equipment using air but that may be a few years until I can justify the next purchase.
I have heard it is bad to oversize compressors and that a compressor that is too large can be very expensive to run. Is purchasing this compressor a bad idea? How much will it cost me per year to run this? It will sit on almost all the time but the mill will not be running 24 hours a day. I don’t have any real leaks in my air system.
Thanks!
