One more ?Dennis, Phil,Len?Anyone.
Thanks guys for the info on my 2 stage ? A few more questions, Is there any benefit to having a vertical tank over a horizontal? Water issues with horz?Build up of rust in tank maybe? I was looking at this I/R below and thought it looked good. I just got rid of my old compressor, due to use moving back east, it was a sanborn 60 gal 2 stage, never had any problems with it but was not happy with the output when grinding. Figured with this one that wouldn't be an issue. Is this over kill? Could I get what I need for grinding out of a 2 stage 80 gal? I really hate to stop and wait for air when I'm in the middle of a job. Thanks you guys are great.

Reason: add more info

The IR you listed could run a good size body shop with several workers. It's overkill for a one man operation.
The vertical tank compressor uses a lot less floor space but other than that there is no other benefit that I've found. For a one or two man operation an 80 gallon unit that puts out 15 or more CFM should be plenty of air for most operations.
My personal belief is that there is no such thing as too much air. If you have the room and 3 phase power bigger is definitely better. I've got a two stage 80 gallon Quincy that puts out 17CFM at 90 and when I'm running my random orbit sanders it's almost running continuously. If I were to use an air polisher or grinder it too would need to run almost continuously to power them. SATA and DeVilbiss HVLP guns take over 13 CFM as well.
The reason most of us top out at 5HP 80 gallon compressors is the lack of three phase power. Few compressors larger than this come in single phase. If you've got three phase power go for the gusto as I've never heard anybody complain about having too much air. Overkill is better than underkill. How many times in a Western have you seen a guy that you thought was dead kill his assailant with his last dying breath. Unload a clip from an M16 into him and he's not going to be pulling the trigger anymore.
I agree with Len, a 10 hp 35 cfm air compressor is quite a bit overkill for one man. You could run 3 or 4 guys of that one compressor. My Quincy compressor is 5hp 80 gallon 19 - 22 cfm and I have NEVER run out of air in the 22 years I've been using it.
It take a LOT more electricity to run a 10 hp compressor than it does a 5 hp unit. Point is it will cost you quite a bit more to run that compressor evertime it cycles. 99.9% of home shops are not setup for three phase power. Its difficult for a one or two man operattion to even get set up with the electric company for 3 phase power. I didn't think I'd ever say this on this site but " look for a smaller compressor" hehehehe.
Thanks for the input guys, what about horizontal vs vertical? No difference? The way the drain is on the horiz. tank, I'm wondering if it will drain all the water out completely ?
Heat rizes, Hot air has less area to ocupy in a vertical so in theroy the horiz. would have dryer air.
I would think gravity will rule with respect to tank draining, imho the vertical
tank will drain completly.
Usually there is no difference in the quality of the air from horiz. vs. vert. Draining either tank is about the same. Most horizontal compressors will have a slight tilt that allows the water to gravitate toward the drain.

Can't believe I'm about to say this, but that compressor seems a little large for one person to use for a grinder. What kind of CFM's did your old Sanborn put out? I'd be willing to bet that by selecting this beast of a compressor, you'd be skipping over numerous MORE-than-adequate models.
But- if fundage, space, and 3 phase power is no issue, then go for it!
Can't see much advantage besides space on vertical vs horizontal. Horizontal might be easier to move/install if that's an issue.
I'd like to know where he lives that they provide 3 phase power to a residential customer?
If he can get 3 phase power I'd suggest opening a business cuz even if that thing isn't running they will be charging you plenty.
