Ok, so I currently have an Eaton compressor on a 60 gal tank. It’s 5 hp motor and it’s rated 18cfm at 100 psi. I have another 60 gallon tank with compressor mount I picked up for $50 and then another 120 gallon storage tank for $200 so 240 gallon total storage. I’m considering another compressor on the 60 gallon tank and plumbing all three together. Prices are listed below for motor and compressor. Was originally thinking an identical setup to what I have. Recall I’m cheap so less is sometimes better but getting ready to setup a cabinet I have to do axle housings and parts. I am by no means a blasting expert. I don’t use much shop air other than for blasting. Thoughts?

5hp @ 18 cfm @ 100 psi $800
7.5hp @ 26 cfm @ 100 psi $1050
10hp @ 43 cfm @ 100 psi $1500

There will be a little truck freight on top of those prices in addition.

If you are blasting big parts you need a lot. A LOT of air.

I’d add the biggest to what you already have.

Thanks Charles, not my wallet thanking you but you get the idea.....

Just rent a scroll compressor now and then. 125cfm can push one heck of a blaster.

Screw compressor? Yeah, not into renting equipment. The last screw compressors we had IR were crap too.

So by using that nice chart Charles provided and going with his recommendation of bigger is best. I’d have 61 cfm available at 100 psi. Guess I should call Eaton Monday and see what they can do. I believe last time I bought motor and compressor head from them. With above figures I was sourcing motor from amazon as I couldn’t find motors on their site. Maybe they can do a package deal....

Found a supplier of rebuilt 10 hp single phase motors. Should be able to cut $300 off the price but with a 10 hp motor and the start load I’ll need a mag starter for sure so I reached out to a friend who might have a good used one in his stash.

And the compressor head I’m strongly considering

That's the one I am using. 4 cyl mag start, 220V 10 HP
Keeps up with everything I have ever asked of it
Sounds cool too!

JR · « **Reply #7 on:** May 09, 2020, 06:45:00 PM »

With all that storage, 18cfm sounds pretty good unless you blast all day.

My 5hp Century has kept up with my needs. In fact I am going to a kobalt (cheap) 3.7hp, 11cfm here at home now. I may add a second tank but the same setup was double the price for 2gal more.

stlaser · « **Reply #8 on:** May 09, 2020, 07:32:46 PM »

43cfm head is sitting in shop, came in a couple weeks ago. Rebuilt 10hp head is at terminal, that rebuild guy well the verdict is still out but atm I wouldn’t recommend him. Even his freight broker had paperwork screwed up so I couldn’t pick up last Friday. They had it as will call and delivery, not sure how that is possible? Buddy of mine sent me a spare mag starter. 60 gallon horizontal tank has been stripped and cleaned. Will need to fab up new mounts for head and motor.

Had to buy some more hockey pucks in bulk from amazon for machine isolators, they came in Friday.

Spare 120 gal tank is in loft, need to purchase black pipe and plumb shop yet.

Will add pics shortly

You going to start jet engines?

stlaser · « **Reply #10 on:** May 09, 2020, 08:58:27 PM »

Roughly 63 cfm, 240 gallons of air storage so I think it will be fine.....

KensAuto · « **Reply #11 on:** May 09, 2020, 09:54:05 PM »

63 cfm?

stlaser · « **Reply #12 on:** May 09, 2020, 10:05:30 PM »

62cfm at 100 psi, the new head is rated at 43cfm at 100......

Pretty big blast cabinet so when I was looking at it for 2-300 hundred extra I could jump about 20cfm and decided to do so.

Business has been good this spring, really blessed considering. Truck build side has been really dropping off but parts sales are double and going towards triple last years numbers so far. Along with axle core assembly and components sales exploding as well.

Well, with a fancy c10 tying up my lift waiting on a duragrip carrier from Tate I decided to start putting the tank together to hold the compressor and 10hp motor. Added pads to bottom along with some hockey pucks. Made a trip to hardware to buy incorrect size fitting for tank drain.

We used a 500 gallon propane tank for extra capacity. It takes forever to fill if you let it get empty. Works great using the little sandblaster and filling the huge tractor tires.

I’ll have 240 gallons of storage plus the piping throughout the shop. That tank is 60 gal, my old compressor is 60 gallon and I have a 120 gal storage tank in the loft as well.

Love to add another tank here and at the ridge. Been checking CL but people want stupid prices for tanks.

stlaser · « **Reply #22 on:** May 20, 2020, 10:14:28 PM »

I believe I paid $300 for the 120 gal unit, $50 for the 60gal in pic and a couple hundred for the other compressor tank but it was only a year old. Contractor had used it to supply air on a mansion build job so all the subs weren’t hauling their own compressors in and out etc.

I got free propane tanks out of the junk yard. They don't like to deal with them and they're pretty thick.

Picked up correct fittings this morning, then mounted motor and added pulley. Cutting mount for compressor frame to bolt to now.

Sounds about right. A quick google foo shows in the ballpark of 50 FLA so would need 60.
That’s some serious air!

That was pretty good, it’s stable as stable as 500# can get mounted to the top of a 2’ diameter tank

Went and picked up seven 10’ lengths of 1” pipe and some various fittings. Doesn’t take much to spend a couple hundred at HD

If it was only that 60 tank maybe, it’s pumping another 180 gallons worth of tank in the shop though

Put a knuckle boom on the ferd flat bed, should be able to do anything you need in the shop, and more importantly, away from
The shop!!

That compressor is amazing, would be perfect on the back of a oil field truck.

110’ of 1” black pipe cut, fitted and hung. All the overhead is done minus hanging the two reels and plumbing the tanks yet.

Slow but sure, all the overhead plumbing is done as of this evening. New hose reels are hung and I plumbed in single drop for sand blaster cabinet.

Yesterday my local electrician wired up the 10hp motor. Just waiting on me to plumb the rest of compressor so he can finish the two wires to the pressure sensor. Waiting on some flex hose from a good friend to plumb the tanks at compressors and storage into the overhead plumbing.

Being that it’s been 90+ last several days I added a second ceiling fan in shop to help circulate the hot air down and out.

Hope that doesn't fall on him. Heck, just the airline should add another 50cf to the system!

Have you used these quick connects? Provest is the main brand but are $15 each.

The 110’ of 1” pipe in the shop adds a little over 4 gal of capacity.

I haven’t used those quick connects, I’m old school
I guess using the brass ones I buy in bulk.
