80 gallon 7.5HP Compressor brands?

[Cue]

I am thinking about upgrading to a compressor with higher CFM for sandblasting. Right now I have the Harbor freight 5hp 60 gallon and the specs say 15.8cfm at 90psi. For most everything it works great but when I am sandblasting (TP Tools 976 cabinet) it runs constantly and cant keep up as well as I would like it to.

Im thinking about a Quincy QT-7.5, anyone got one? or a brand they recommend over another?

I have been quite happy with my Puma 7.5HP TUE-7580VM

If you get the new one by x-mas and need to find a home for your HF one, send me a PM. Just so happens I am in the market for that exact compressor for my dad who lives in your area.

Which nozzle set-up does your gun have? Have you tried the low flow nozzle? It does work good and would be a lot cheaper to try changing out the nozzle for $14.00 over another compressor.

I am using the medium nozzles. I am afraid I am used to how well it blasts now that if I go to a smaller nozzle I will be disappointed
I may give it a try though

Hard to go wrong with a Quincy. If you want some other quality options, check out BelAire 418VL, Chicago Pneumatic RCP-C7581VS or RCP-C7581VSC2 or C-Aire A075V080-1230

You never know......and at fourteen bucks vs a couple G's, I would try it.

The Quincy QT series you can buy at the big box stores aren't their best ones. The are more like their middle tier. They spin fast and can be noisy. The best Quincy's are the QR series you'd end up buying from your local compressor dealer or something like that. The RCP-C7581VSC2 that CompressorPros.com linked to is basically a Taiwan import pump head based on the legendary Saylor Beall 707 pump. A lot of companies use the pump, including Eaton Polar Air. Quincy's lower end series, CP, and Bel Air are all owned by Atlas Copco. NAPA and US General compressor that you have from HF are all made them too. Generally the paint color is what differs. The best ones money can buy are the Saylor Beall with the 707 series pump, or Champion R series/Advantage Series with the R30 pump. They will be far more expensive however. Another alternative, is simply to buy another HF 5HP and plumb them up in parallel. Nothing wrong with doing that unless you're concerned about floor space.

What he said ^^^^^

Champion is truly good stuff, Quincy has fallen off except their highest tier.

Comparing products on brand names only (like the title suggests) does not always give the best answer.
But on brand names of compressors, you will find very few people who have bad to say about Champion.
An R15 or big-boy R30 will give many hours of smooth running plentiful air.
But like many quality things, have a thick wallet. Buy once, cry once.

Assuming the low cfm nozzle doesn't work what about buying a second compressor? For $500 or so you could get a new 3hp 60 gal compressor to piggyback with your current compressor. Install a valve so most of the time you only use the current pump. When you need the extra air open the valve and use both compressors. It's probably cheaper than getting a 7.5 hp unit even factoring in selling the old one. It also gives you a back up in the unlikely case that either compressor fails.

Just as a point of reference, this 60gal 3hp compressor from HD is $500

I'm guessing its a CH based model. It claims 11.5 CFM at 90 psi. Add that to your current 15 and you are over 26 cfm. In comparison the compressor your considering is 23 CFM at 100. So about the same pressure but for well over $2k.

look for a compressor with aftercooler or make one.

i convertered my quincy 370 from 10hp 3 phase to 7.5 single phase about 1100$ into it.

buying new i would check champion, saylor bell, curtis,

Thanks for the recommendations. I only have room for one vertical compressor so adding another one is out. I have a aftercooler that I built for this one so am familiar with them. Might try a low flow nozzle set first and see how that does.

Yes, try the nozzle first, and then keep an eye out on Craigslist. I've got too many 80-gallon 2-stage compressors now (a Curtis, a Snapon, and a Quincy) thanks to my CL addiction (plan on keeping just the Quincy). Have cash in your wallet and your truck gassed up, because the good deals on compressors disappear quickly - in some cases, just a couple of hours (business closing, and they have to get out THAT DAY so whoever gets there first with the $ gets a 'you ****' deal).

I bought a Quincy 80 gal two stage pressure lubed for 1550.00 off of CL. I'd go with a pressure lubed if you can afford it. I have the TP Tools blast booth with a carbide nozzle and it's no problem for anything I want to run.

I'm only a couple miles from you, if you decide to sell the HF one, let me know!!!

Polar Air --- 26 SCFM @ 175psi on 80G, lots of Chinese parts, but no complaints so far (over two years of operation)......

Have sandblasted everything from walnut shells (light work) to alum oxide (rust) ----it's done the job removing rust I thought would never come off.......
