40 Gallon Puma two stage

[Crazy68Dart]

The new garage has an attic, and I want to take up the least floor space. From what I can find on these models, they are "relatively" quiet. I am looking to be pretty budget conscious (a lot going on right now in my life), and thinking I can always add/plumb a receiver tank in the attic for more reserve capacity in the future.

I have been using an IR single stage twin (at my old house) rated I think at 11.3 or 11.5 CFM @ 90 PSI, 3 HP, 60 gallon. It did okay, but produced a lot of water, and for what it was rated seemed to work pretty hard.

I want to get into a two stage for the various benefits, hence looking at these smaller Puma's. I've also been looking on craigslist (for quite a while), but either they are a large compressor, older compressor, unknown life/use, etc. for not much of a savings/value, if any at all.

Anyone have either of these and can comment on performance?

Thanks!

Interesting, the label from the IR I have is attached. The same model selling now is not rated the same, hrm... I have had mine for around 10 years or so, originally purchased at TSC.

I can tell you I bought some rebuild parts for my old Speedaire from the local air compressor guy. He also travels fixing huge industrial compressors. He was all about Puma compressors but also told me after I rebuild mine it will be better than any box store **** you can buy these days.

Thanks. I can't find a whole lot on this particular compressor (the Puma). From a space standpoint, I don't think there is much difference between a 40 gallon and a 60 gallon. Dimensions indicate the 60 taller than it is larger in diameter.

Any other insight welcome! Thanks.

Well, the 3HP Puma doesn't make much more air than the one you have now, so unless you are going to use them in parallel, I wouldn't even consider that one.

I'm not sure from your original post where you are planning on installing the compressor - are you thinking of mounting it up high? If so, there are several threads on this topic here.

Understand. My point above with the IR was that I am not sure I believe the rated output of that compressor.

I am considering mounting it on a platform and/or boxing it in (eventually) for noise reduction.

It's the same as the 80gal but with a stubby tank which you can check the review of the 80 to get some ideas
Any reason you cannot get a horizontal 80gal?

 

[matt_i]

I haven't seen the top end but I'm guessing its a two cylinder non-staged pump. In other words, rather than the cylinders being piped in series to increase pressure, they are running parallel, each dumps into the tank. More volume.

In other words, a T-30 2 stage 5hp is 14.7 scfm at 175psig. Yours is 11.3 scfm @ 90psig.

Are you sure of this? The pump/compressor and motor are the same? I am going to send a note to Puma to get more details. I could maybe do horizontal and put in attic, but I would prefer to leave the mechanicals on the main level for ease of maintenance/service. Otherwise, I could put a receiver tank in the attic that would not need much attention once plumbed in.

It is a two-stage.

Bringing this one back up...

Looking at this high CFM 60 gallon single stage unit now as well.

Looking at other mfgs too, but in general I can spend more money on a similar size two stage, but they do not have the same speced output (@90 PSI) as the PK7060 above.

I understand the differences between the two types, 2 stage being more "efficient", etc. but when it comes down to the raw output, its hard to ignore the difference.

Will the single stage triple generate that much more heat/water? This is for home use, typical air tools (highest consumer a D/A sander), and possibly a blasting cabinet some day.

Thanks.

That Puma looks decent.

2 stage are more efficient...."at higher psi." For anything under 120 psi, a single stage will work. What tool requires more than 120 psi?

If you have moisture problems invest in an aftercooler/water separator.

This one looks like a good value:

Crazy68Dart, I have the Puma 5040. Do you still have a question about it?

Crazy68Dart, I have the Puma 5040. Do you still have a question about it?

Sure, how do you like it? My question, how did you decide on that versus possibly a high CFM single stage? I assume space was maybe more of a consideration?

Fundamentally, just trying to get it straight how @ 90 PSI -- CFM from a 2 stage differs from CFM from a single stage. I get the physics of it all, the fact that more air is "stored" at 175 PSI, but the rating at 90 PSI is still the rating at 90 PSI, no matter how the air was compressed.

If guys are buying two stages to run tools at a higher pressure, I get that too, but which tools?

Thanks

I picked up the Puma 5040 awhile back and I really like it. Compared to the screaming banshee Craftsman I had, it's very quiet. It seems to fill very fast. Other than a brad nailer, I haven't run any power tools with it yet, but it has no problems keeping up with a large air nozzle when I'm blowing dust and debris out of the shop.

I was replacing a noisy oilless, and had decided to replace with a two-stage without much thought. The form factor lead to the Puma. With its stubby tank, it would fit under my cabinets even with the added height of the McMaster-Carr vibration isolators.

With its 3450 rpm 5-hp motor, the 2-stage pump runs at about 860 rpm. The largest user in my hobby shop is a HF blast cabinet; the 5040 keeps up just fine.

10 cfm is plenty if you are just going to run a ratchet occasionally. You may not need that much. Tell us what tools you are going to run. Does the 10 cfm unit keep up now?

If the only problem with the current unit is that it puts out a lot of water, run the air through 30 or 50 feet of 3/4 inch pipe, that will cool the air and drop out most of the water. You could also buy a refrigerated air drier, which would be more effective, but use more energy and cost more than pipe. The water in the air is mostly a function of the local humidity; I live in a dry climate, so I don't generate that much water, usually.

If you are going to use air sanders or die grinders, you should have more than 10 cfm. I have 16 cfm, and often run air angle die grinders more or less continuously; that seems to meet my needs.

s.

The air compressor didnt put the water in the air. It was already there. The air doesnt know how or why it got squeezed. Until you add more or let some out, the tank has the same amount of air inside. If it is heated, the pressure goes up. Cooler air holds less water.

A tank with higher pressure (at the same temperature ) has more cubic feet of air in it than the same size tank at a lower pressure (at the same temperature ). The same number of cubic feet can be pumped in a larger tank at a lower pressure with less energy than a smaller tank at a higher pressure.

A single stage is more efficient up to 125 PSI and delivers more cfm per watt. Both pistons add air to the tank.

A two stage is less efficient because the second stage does not add an additional air that was not compressed by the first piston. It can hit a higher pressure.

No small two stage compressors other than the Puma are made today. If you want small high pressure, they're it.

 

[Crazy68Dart]

Thanks everyone. Die grinders and sanders, yes. Not 40 hours a week, hobby stuff, but the current unit wouldn't keep up. It might be worthwhile to look into the current compressor. It has always seemed slow to build pressure, but I was thinking I was just expecting too much out of it.

I don't have anything (right now) that would benefit from the higher pressure, but I suppose maybe a blasting cabinet might. I like the small 5040 due to the form factor and size.

I appreciate the comments.

I have the Puma also. I wanted a 2-stage, and was on a budget. I'm in a woodshop, and only do metal grinding ,cutting ,etc. once in a while. For my needs , its great . All my finish spraying is HVLP , so no problem there. I was not going to buy another single stage screamer again, thats what I was trying to avoid.
