Compressor Question

[Kejtar]

Just got my Harbor Freight mailer in and they have a 2hp 115psi 8 gal compressor by central pneumatic. It's supposed to output 6 scfm @ 40 PSI, 5.0 SCFN @ 90PSI, 4.2 SCFM @ 115PSI

Can anyone comment on it?? Good/Bad/Unknown?? I like the price (Craftsman ones that I like were over $250!!)

It's okay for airing up tires but it doesn't have enough capacity to keep up with air tools. 115 psi isn't really enough for an impact gun, and die grinders need lots of CFM or they die out on you. I'll have to get the specs off the tank tomorrow, but I'm pretty sure my compressor is larger than that (it's a 3 horsepower, 15 or 18 gallon tank) and when I'm trying to use a die grinder I'd estimate my "duty cycle" is about 20% grinding, 80% waiting.
