How many cfm

I've been looking at HVLP guns lately, but I don't know if my compressor will push one.
My compresser is a Crapsman 5hp single stage on a thirty gallon tank, running a 220v motor (don't know how many horse).
Anybody know if that's big enough for an HVLP?
If it isn't, would it help if I hooked up another tank to a manifold?
Local farm and home has thirty gallon air tanks on sale for $25.

My 5hp/60gal single stage would run out of air about halfway through a complete repaint using the HVLP guns. I bought a 7.5 hp/80gal two stage and it doesn't have a problem keeping up. If you are planning to do a lot of painting and heavy body work, i.e. board sanders, D/A's and the like, you really should step up to a two stage compressor.
If this is a one or two jobs a year thing your current compressor will be hanging it's tongue when you get done but it will do the job, although marginally.

Thanks Astro,
Yeah I should probably upgrade. I've had this compressor for ten years. Still works good, but even my little die grinder makes it heave. An in line sander would definately make it puke.

Do your upgrade and sell the old one... I've still got to get rid of mine but it runs great and I figure it's worth 2 or 300 bucks... nothing to sneeze at and you can put that toward some good air tools...
