All,
I'd like to purchase an air compressor for the new homestead, and cannot seem
to make a decision. I've gone through the archives (read -> old digest emails
saved on PC), but have yet to come to a decision. But, I do have specific
questions.
Here are the basic assumptions of use:
1) basic carpentry equipment (nail gun)
2) basic automotive (air ratchet, impact gun, air chisel)
3) more advanced automotive (blast cabinet, eventual painting)
That leads to several questions:
1) How much max PSI should I get? Most units are between 125 and 135 PSI. A
few offer 150 PSI. How important is this factor? Should I be concerned more
with scfm?
2) What exactly is scfm? I know is has to do with air flow, but what does
the acronym stand for? And how much is enough? From one of the digests:
at 90 PSI
3/8 in. ratchet 3 scfm
1/2 in. impact 4
air hammer 3.5
cut off tool 4
nibbler 4
3/8 drill 7
6" DA sander 4
orbital sander 10
sand blaster 6
painting 4.5-7
3) What about oil vs oil free? One stage vs. two stage? I would prefer to get
an oil compressor for longer life, but how will that affect the air tools?
Will I have oil all over the place?
I'm looking at 6.7 scfm unit.
