Hello, my uncle just gave me an air compressor to use in my garage. It is a 6 gallon pancake style compressor that's 1.6hp(2.0hp peak) with 3.4cfm @40psi and 2.7cfm @ 90psi. I know its not a big compressor and isn't ideal for a garage, but hey it was free! I would like to know what tools I can get by with using this compressor. I am going to get an air nailer or 2 for house work, but as far as the garage, can I use an impact gun and an air ratchet with this compressor? Most of the impacts and ratchets that i have seen on harbor freight etc.. seem to be rated around 5cfm. Can these still be used with a lower rated compressor? Would I only get half the power of these tools using this compressors ratings? Can these tool be use on a compressor that doesn't meet the full air requirements of the tool? I would only be using these tools for general maintenance like tire rotations etc.., so can I by with this compressor using these air tools? My plan is when i refinish my garage down the road i am going to get a bigger 30+ gallon compressor just for the garage and use the pancake one as portable unit, but this is a few years away, so i am hoping i can get some air tools to use for general maintenance on my vehicle until i get the bigger compressor. This is my first compressor and don't know much about them or the air tools yet, so that's why i am posting these questions. thanks for all the help.
