Used IR Compressor Value?

[seanb02]

Hey folks, have an IR air compressor that the tank developed a leak on after about 20 years of service. 5hp, 60 gal unit. Pump and motor are still working great - briefly contemplated getting a new tank for it, but decided to upgrade since over the last couple of years I have increased my air tool usage in the farm shop and I could draw the IR down pretty fast to where it couldn't quite keep up. Upgraded to a CP 7.5hp 80 gal unit as a replacement.

What I would like to know is if there is any market for selling this rather than just scrapping the whole thing? I'll post up some pictures if it would be helpful, but it is very clean looking, kept indoors. Oil was changed in the pump every few years, so should be ready to bolt on a new tank and keep on going with it. Link below to what appears to be the same exact unit at ~$1600 new:

Give me some ideas on value so I know what to list it for locally on CL and Marketplace, I really don't know anything about the used market on this sort of thing. Thanks!

no comment on the value, but I would remove the tank so someone doesn't try to weld it up & put it back into service.

Where are you located?

the parts are worth more than scrap

Seems highly dependant on the area you live in. To me you have the expensive pieces of an air compressor and need the relatively cheap piece. If you have time and space you could sit on the pump/motor/plumbing and find a new tank used for cheap money and then sell it to recoupe some of your money. Separately everything is worth considerably less and usually harder to sell. If you can find a decent tank I'd think you could get ~1/2 the cost of a new unit

I would much rather just sell it complete rather than in pieces, I highly doubt anyone would be very much inclined to try and save the tank.

Southern Oregon (Grants Pass). I'm sure that it is worth something to someone, but the trouble is figuring out a starting price to list it for.

You'd be very wrong...cheap people do some crazy things and would definitely burn a couple rods into the tank and call it a day.

I'd figure $200-300 for pump and motor?

It really isn't worth my time to try and put together a working unit to sell even if it nets more in resale value. If I was going that route, would probably find a 20-30 gallon tank and a Honda GX160 motor and turn the pump into a field unit for my service truck.

Okay, but don't overestimate the thinking of the general population .

Can't protect everyone from themselves, but it might be prudent to write on the tank DO NOT USE just to cover myself, or maybe cut a window in it.

I would torch several holes in the tank, enough to make it unusable, then put it on Marketplace for $100-$200 to make it be gone.

 

[FMB4]

Finn is correct imo.

 

[seber]

I'd like to buy the motor if you are willing to ship it.

 

[PoorUB]

The value is questionable unless someone has good used tank laying around. Price a new tank then add in the hassle and even if the pump and motor was free it would be questionable if it is worth it.

Is it a real 5 hp, or one of those over rated compressors?

My bet is you might get more for it stripped out. Sell the motor separately from the pump. Ask $200 each with separate adds on Facebook Marketplace.

I don't think it is over rated, this is not the same IR 5hp model that places like Tractor Supply carry for like $900 - this one is a little more expensive industrial version. Still not a high end compressor, but really it has held its own just fine in a farm shop for the last 20 years.

pardon my ignorance but could one not just weld it up and pay to have it hydrotested and call it a day?

Someone else can probably come up with a better answer than me, but the way I see it is that yes it is possible to do. However, to do it right the entire bottom cap would need cut off of the tank since the majority of it is very likely compromised. Then weld a patch to the inside of the cap forming it into the same shape as you go, then weld the cap back onto the tank. Quite time consuming to do right, then pay the fee to have tested and it may or may not pass. Seems like there would be minimal savings over just buying a new tank and calling it a day.

Most folks that would buy something like this to repair would probably just drill the hole out bigger and then drop a bolt or something in there and weld up the head and put it right back in service. This method does not address the other potentially weak areas of the tank and skips over the critical testing portion entirely.

I'm going to hijack my own thread as I just discovered that the pump is the same model that IR uses for their truck mount compressor setups that sell for $3500. They use a 13hp GX390 motor to drive it and advertise about 25 cfm. Since the electric motor that drives it now is 5hp and it is around 17 cfm, why would there be any increase in cfm ratings by just putting a bigger motor on the same pump? Isn't it still driven at about the same RPM which should result in the same amount of flow? Or is the pump actually capable of that much more by increasing motor size and probably a different pulley to drive it at higher RPM?

So if I purchase a motor and a little 10 gallon portable air tank to use as a buffer tank I should be able to easily turn this thing into a compressor for my service truck for around $1500. Anybody have any ideas on what size pulleys it would need to get there since I can't find any parts on Ingersoll Rand's website? Or could I drive it with a smaller engine, maybe a GX270 and still get decent output? Just seems odd to me that the motors are sized so vasty different for the same pump.

 

[finn]

Use the ratio of the two cfm values and multiply by your current pump speed to figure out how much “ overdrive “ you need.

 

[Jswain]

Most ~5hp rated pumps can be driven by 3hp, 5hp, and 7.5hp motors, and a lot of the older ones you can find max rpm ratings for each size motor. What will change is the max rpm and the CFM delivered. The bigger the motor the more capable it is handling then load when the pressure rises at the increased rpm.

Good thing you found this out before you turfed it all

 

[seber]

You will also need a different pressure control. Instead of shutting down the motor you need to valve the output to atmosphere.
