I need a new compressor, one that I can roll around from time to time and
than can power my 6cfm (@ 40psi) spray gun.
The best deal/CFM seems to be the 60gallon/3hp/220v Husky Pros from HD
followed by their 30gallon/2hp/120v brethren. The former is somewhat
top-heavy (perhaps even more so than a drill press) and rather averse to
motion but has plenty of output for my needs. The latter is downright agile
for my mobility needs but is a rating of 6.6cfm (40 psi) sufficient? (I
know my twin-tank Makita compressor is definitely not.)
Any relevant experience/problems with either of these options? Does anyone
keep a 60gallon compressor on a mobile base?
Cheers, Shawn
PS: The HD variants load the tank only up to 135psi, while the Lowe's
models go up to 155. I suspect the latter will cause more noise and heat
than I want to deal with, but I have no real experience on that matter.

Amen, brother. This is obviously coming from a guy with high pressure
spray experience, eh? ;^)
Most of the time, the higher pressure is just wasted, and is only
provided by changing out the regulator unit on the machine.
But true high CFM takes a higher capacity compressor head and usually
a better motor. Higher CFM provides constant high pressure with less
drop off than a high pressure unit with few CFM.
If it were me, I would go about this differently. I would take a look
at the components I am trying to power with compressed air, then match
the compressor up to my most air hungry tool.

Very true. I did not mean to mislead on that point - I got (get...) carried
away by encouraging people to look at SCFM rather than pressure, as the real
measure. Almost every compressor buyer looks at pressure...

Absolutely. I have said this many times in past posts, and maybe I was
errant in not specifically stating it in this response. Good cover Robert -
thanks for adding that.

Hell no. Think about it - as you said - quite top heavy. Stationary is
exactly that - not mobile.

Don't get suckered into the psi rating. Look at the SCFM rating - that's
what matters. Why would you need 155 psi? What you need is the air volume
delivery. Absent that, all of the psi in the world is just a great big old
bottle neck in your compressor.

By you figures, the 30 gallon has 10% more capacity than your stated
need.
If you are torn between the two go with the "stationary" up right 60
gallon compressor. Then buy a $79 cheap Harbor Freight compressor for
those odd times you need the portability.
