Quincy 325 vs 340 need help deciding

[Bstoehr83]

Working with my local Quincy rep to order a new air compressor for my home and having trouble deciding what to get. The compressor will be used on the weekends for painting my cars and bodywork. I do a lot of grinding and sanding so I want something with near 100% duty cycle. My options are 325 5hp 80/120 tank, 340 5hp 80/120 tank or 7.5hp 340 80/120 tank. All would be single phase. The 340 hp is almost 2k more than the 325 with the same CFM but the pump RPM is in the 500s vs 700s. The 7.5 is only a couple hounded more than the 5hp, a little over the 6k mark.

I’m not too keen on spending 6k but This is intended to be a once in a life time purchase and I don’t want to regret buying to small.

Does anyone have any recommendations on which pump, motor and tank size I should be considering.

Is the step up from the 325 to 340 worth the significant increase in price, especially if I stay at 5hp and just get the 200 rpm drop?

I didn’t ask about the 350, assuming that would be way to much money with no increase in benefit.

Is the 120 tank a lot better when doing a lot of sanding/grinding?

Also, Should I be concerned the Quincy rep isn’t getting me a good price since I’m an individual and not a company? Shipping is not included in the price and not sure if that is normal.

I’ve been looking at champion and Saylor-Beall Beale too but think Quincy maybe the way to go.

Any help would be appreciated

The 325 will do it all. 5 hp is the benchmark for auto body and paint.

 

[Bstoehr83]

Thanks! Any idea if an 80 gallon tank is sufficient with the 325 pump or would it be better to step up to the 120 if I have the space.

Being as I have a QR 25-325 in our 6 man fab shop, I completely concur with sberry. My 5 HP 325 sits on a 120 gallon receiver, with a 240 gallon receiver sitting next to it for a 360 gallon total capacity. We utilize many different pneumatic powered tools along with two CNC machines that use a lot of air during tool changes. With the large air storage capacity, the compressor doesn't need to cycle very often, which is better on the motor.

You'll be more than happy with the 325 on a 120 gallon receiver. See if your dealer will throw in a belt guard mounted aftercooler. I use a Bekomat auto-drain which has worked flawlessly for the last 15 years. I also installed an hour meter on the mag starter so I can keep track of maintenance.

 

[sberry]

In a fab shop hour meter would be more relevent. This type of comp would need an oil change and belts tightened in a decade in a home shop. The bigger tank gives it a bit more range and helps a little with operator timing to extend run cycles. The 80 is suffecient, the 120 a pinch better with lots of sanding and a journeyman operator. Not a deal breaker either way.
I have a demand and backup but use 3 hp for this work on 200 gallons of tank. 5 wouldn't need the extra in home type shop.
As Tool pointed out they using a 325 in 6 man shop, if it works for him it will probably work for you too.

 

[Bstoehr83]

Awesome, the rep quoted me $3800 for the 325 5hp single phase on an 80 gallon tank and magnetic starter excluding shipping and sales tax. I got a little worried when she said the aftercooler was $1,000 extra but seems to sell for 600 online.

Any idea if the quote seem reasonable?

 

[The Tool Tyrant]

$3800 seems VERY reasonable. Installing an aftercooler is simple, a little tube bending and a couple of fittings...easy-peezy. Personally, I'd go with the 120 IF they don't want too much extra.

Thank you!

That's JUST the pump! That's why I say $3800 is VERY reasonable.

 

[dkmc]

Hey, you're only buying it ONCE. Go with the 340/ 7.5.....someday when you want to do sandblasting you be glad you did.

And......I have zero problem spending other peoples money.

 

[blazemaster83]

I am rebuilding both a 244(kinda rare?) and a 390. Hopefully that will be enough air for a 1 man shop!

 

[pcmeiners]

$3800 is not off the mark for new retail. Shipping, for another compressor I have (same weight) was around $500. The QR series is a pro series, do not consider the lower priced Quincy compressors which are no better than the average compressor quality.

"Also, Should I be concerned the Quincy rep isn’t getting me a good price"

Quincy reps do not give a **** if your a business or individual, your not going to get a good price off one of them. A client of mine purchased a QR350 recently for his printing company (presses use a lot of air), he could find no rep giving a discount. As a note, the QR350, (120 gallon) takes up a good deal of space and is massively heavy.

Have a qr325, 80 gallon vertical , purchased second hand with few hours on it, $1600. For NYC that is a decent price. With all the QR series compressors on CL , Ebay, and auctions, with a little patients you can get a lightly used one at a decent price.

Considering parts availability, support, quality, the Qr series compressors are the best buy. Other will chime in with other brands which are in the same quality realm but Quincy pumps are a step above them. Look on Ebay or the Internet as to ease of obtaining parts, look on the Internet as to support from businesses and individuals. There are dozens of YouTube DIY repair videos, thousands of forum repair, maintenance and help references. If you consider any other brand, do you homework and search the web for references/parts etc. before deciding. Quincy QR series are the most supported compressors.

As to a an hour meter, I have one installed. You can keep track of oil changes, filter changes, hours before any other maintenance such as lubrication, valve cleaning etc

As to an after cooler, the following has copper tubes, swirl tubes, 300 lb max pressure...
alumuminum tubes are fine with oil, but not with air with acid air pollutants.

Hayden industrial coolers, either a 1260 or 1290 ...

1260....

https://www.ebay.com/sch/i.html?_fr...&LH_TitleDesc=0&_osacat=0&_odkw=hayden+cooler

1290...., (not the OC 1290), size is more for larger then the QR 325.....

https://www.ebay.com/sch/i.html?_fr...itleDesc=0&_osacat=0&_odkw=hayden+cooler+1260

A $1000 is a ridiculous price for an after cooler, which takes little time to install.

^^^^Everything PCM stated is spot on! Nice lead on the aftercoolers too.

The QR 25-325 will outlive you AND your grandkids if properly maintained.

Agreed!
QR is the way to roll, avoid all the others.

dkmc should know...he's got one for each day of the week (except Sunday...of course)

 

[dkmc]

Although I do have a couple that were only used by little old ladies on Sundays to air out their laundry.

I can just see the wheelchairs lined up at English town raceway, burning rubber to get traction. Interesting as I often wondered if anyone modifies them for extra speed, as I always think they are to slow.
As to tools I need no excuse, if I see a tool I do not have I want it.

Dkmc....

I did not see your list of compressors until today, WOW.

PC, you won't find any of our wheelchairs at a drag strip, they're more intended for the 'Destruction Derby'. We specialize in chairs for the sport of 'Wheelchair Rugby' (Murderball) which is the only 'full contact' wheelchair sport. Google 'Wheelchair Rugby Hits' and you find a few videos showing some good hits. All chairs with the red spoke guards and rear guards are our chairs.

As far as tool buying excuses, heck...it's Wednesday is a good enough excuse for me!

As far as compressor count goes, I too have way too many...I'm afraid to start counting...no, really.

I woke up this morning, good enough for me.

Wheelchair Rugby. I checked out a couple of the videos, cool !
Some of these guys play really rough.

Both of you... And I thought I was bad !

 

[u3b3rg33k]

the QR stuff seems nice.
There's a 25hp QR-25 at work that's older than I am and it just works.
The secondary compressor was a splash lube, and is being replaced with a QP-7.5 with a drive so it can just sit at whatever RPM will hold pressure.

 

[930dreamer]

I'd go with the 7.5hp compressor, that will supply a blast cabinet nicely, or look for a used set up and save a bunch of cash.

Noice!!!!
Great to see I'm not the only compressor whacko on this forum.....HA!
Now, calculate and let us know the combined CFM of all units total.

[sberry]

How good is the electric supply and how much sandblast is there to do? Some extra, 2.5 hp is certainly better.

 

[MKSJ]

No doubt the Quincy 325/340 will last for many years, but maybe consider the amount of hours of use and CFM you plan for you may not need that level of durability. Most splash lubricated air pumps on the better compressors are rated at 20,000+ hours. I have the Champion HR5-8 and it will outlast me. They do have a pressure lube version but couldn't see spending the extra $$ unless it was a commercial operation. Mine came with an after cooler, auto-drain, low oil shutoff, etc. The next size up 7.5 Hp HR7-12 is a V4 pump running at 575 RPM, which should be a lot quieter then the Quincy 325 running at 900 RPM. About $3800 with everything, 7.5 Hp, 120 gal tank, after-cooler, low oil, auto drain, etc.

I purchased mine from Pacific Air, very good price and no shipping charges as it is drop shipped from the manufacturer. Either way get an after-cooler, makes a huge difference in the moisture drop out, for painting you will probably want a compressor dryer in addition to filters. I use Norgren dual filters on both of my compressors, but lots of good alternatives.

Quick follow up question. For about the same price shipped I can also get a Saylor Beall 5 hp pressure lubricated 707 pump with 120 gallon tank single phase(free shipping, no sales tax). Cfm is slightly higher and rpm is insanely low, like 450. Quincy 325 still a better setup?

SB's are also awesome pumps. You really can't go wrong with a Saylor-Beall...especially since you're going pressure lubricated.

 

[dkmc]

I'd get the 325

 

[sberry]

Agree about 20 hrs. Most outlast the owners.

Okay, enough of this BS, Bstoehr83...did you pull the trigger yet?
