Anyone have info or used a IR type 30 253D?

[hondacivic247]

So a older ingersoll rand 253d type 30 compressor with a 80 gallon tank came up on Craigslist for $500 I don't know a whole lot about it besides it being a 2 stage that's intercooled and possibly aftercooled. I tried finding the cfm and it looked to be like 19.7-27 or something like that.

Was wondering if anyone knows the specs on that pump and if there any good?

It sounded good running only downside is its 3 phase and a new 5hp, 184t frame Weg motor will set me back 5hp to make it single phase so I would be in it for 900 if he can't come down on the price any.. which there's a 80 gallon quincy 325 that's a roc100. For 550 bucks that's got a 5hp single phase marathon electric motor.

I just got him down to 350 on the price and will cost me 100 in gas + 400 for a new motor if you guys say it's better then a quincy 325 I may jump on it. I'm looking for a compressor that makes at least 18+ cfm as I just sold my 2 stage emglo that made 16-17cfm

That 253 compressor is a slow-turning beast. They haven't been made in about 25-30 years so the fact that the compressor is still running is a testament to the design.

I would take the Quincy over the IR everyday and twice on Sunday.

 

[hondacivic247]

Think the IR was made in 68 as that was the last 2 # in the serial code.

So why would u choice quincy over IR? I know the quincy is pressure lubed and the IR isn't but the IR has a bigger bore not sure on the stroke and makes more cfm.

I seen a video on YouTube of someone saying it took 7 mins to fill either a 60 or 80 gallon tank to 175psi with the 325 which seems slow. My emglo filled my 60 gallon to 175psi in 5 1/2 with a 5hp and max pump speed it was a GT model.

 

[hondacivic247]

Do you know the min - max rpm for the 253d pump?

The Quincy is far and away the best machine of the three. Why are you wasting time? You're gonna lose out on it. The old IR is a very good pump as well but is a bit cheaper and cruder design. It's also a reed valve design, which makes it somewhat second-tier to the Quincy.

 

[hondacivic247]

The only reason I consider the IR is that it makes more cfm. Does anyone have a quincy 325 here that can tell me how long it takes to fill there tank to 175psi and what size pulley you use. I just don't want to get the quincy and be disappointed that it takes 7 mins to fill a 60 gallon tank. I'm looking for a compressor that can fill the tank in the 5 min range like my emglo GT, 5hp I just sold.

 

[MacMcMacmac]

Either machine will take longer to fill a 20 gallon bigger tank.

The IR will not make more CFM than the Quincy when it is sheaved for proper operational RPM for a 5hp motor. It is basic physics that 5hp will produce x number of CFM, based strictly on the amount of work that can be done with 5hp. The 253 is probably capable of higher rpm, with the proper pulleys and a larger motor to turn it. Most compressors have a horsepower range in which they can operate. The pressure lubed ones have a wider range, since they don't depend on rpm to send oil over the crank, rods and bearings like a splash lube does. Anything over 18cfm is going to require a bigger motor, unless you want to constantly run your 5hp overloaded, which is a no no for many reasons.

If the IR was built in 1968, the Quincy already has a ~20 year advantage over the IR in terms of tank corrosion, wear and tear on the motor and components etc. Buy the Quincy. It's the best reciprocating compressor ever built. I say that after 20 years in the compressor business.

 

[MacMcMacmac]

BTW, a 325 is capable of 500psi when set up properly, so that should give you some idea of the relative quality of the machines. The Quincy QR-25 series bottom end is also used for Corken oil free gas compressors. You won't find anything tougher.

 

[hondacivic247]

I know the quincy is is the best but I'm still leaning towards the IR after speaking with a friend that restores compressors he just did a 325 and a 255 and he said there bullet proof but real tough to work on there not simple like the IR. I'm pretty mechanically skilled but so is he and he has a machine shop with more tools then I. I just don't want something to break and not be able to fix it easily.

What sort of cfm should I expect from the 325 with a 5hp

Here's the quincy

 

[MacMcMacmac]

I wouldn't call a 325 tough to work on. Once you know how the controls work, the mechanicals are as simple as anything else, there's just more parts, and better built ones at that. Yes, the IR will be much simpler to rebuild, that's a fact, and the rebuild kit will probably be cheaper, and the rebuild itself will go more quickly. If you are looking to rebuild the unit, the IR would be the way to go, but I am sensing you are looking for something that is still operational.

The Quincy will be in the 18cfm range at 5hp, which is where the IR will also be. If there is any great discrepancy between the two, something is not running right.

The (suspected) 20 year age difference would still sway me towards the Quincy.

And to be perfectly honest, despite my Quincy boosterism, the quality of either machine will be greatly affected by the environment it was operated in and the amount of maintenance it was given over its lifespan. I took apart a 325 once that had been operated in an area with lots of ammonia fumes and the cylinder head and components inside looked like they had been sitting at the bottom of a lake. I've also had Quincys run on 15W40 that I had to hammer the valve bodies out of.

The quincy looks to be in fair shape the guy still has it hooked up. So i sent him a message and told him I would be down this weekend if he still has it

 

[hondacivic247]

Wouldn't a compressor with a bigger bore and stroke with the same hp motor pump more air/ make more cfm with the same size pulleys? I beleive the IR is a touch bigger bore and stroke then the quincy hence why I thought it would make more cfm

 

[Charles (in GA)]

5hp is going to give you 18 cfm. Don't matter who's compressor it is. If it has a larger bore, or stroke, or both, it will have to turn slower for the 5 hp motor to not be overloaded. Turning it slower takes away the advantage of size, and you end up with the same output.

 

[hondacivic247]

What's the name of the tool I need to check how many amps the motor is pulling under load so I can run it safe? I have a voltage meter bbut nothing for amps. The motor I want to put on is a 5hp Weg single phase 184t odp motor my emglo had one and its a beast had a 1.25 SF seemed better then the baldor 184t

 

[hondacivic247]

Forgot to mention it spun the emglo GT pump to 1044 rpms with a 8in pulley no problem thing is solid rolled steel cconstruction weighed over 100 pounds
