How much to pay for IR compressor

[dirkelstein]

Hi,
I am looking to buy a compressor that can handle my soon to arrive HF Sand Blast cabinet. Looking around I found a IR #2475 7.5HP, 80G beast. The motor is 230V/32A single phase. From what I can tell, the compressor has an aftercooler and electric drain. Pretty much loaded up with all the options from the factory. Current owner purchases in 2007, so about 5 years ago and I am pretty sure it has low hours. I will need to hire somebody to move the compressor ~20 miles to my garage. Thinking that move will cost ~$100, maybe $200?
Current price to buy this compressor new from air compressors direct is $2,500, delivered.
Any suggestions on how much to offer the current owner? Is $500 fair or am I stealing it at that price?
Appreciate some help and advice.
Cheers!

If you offered me $500 for a compressor like that, I would have unkind words for you, and the conversation would then abruptly end, and you would go home without it, but that is just me.

Does the current owner have an asking price?

 

[Journaler]

Pretty sure you could rent a Uhaul with lift gate for less than $200/day.

 

[dirkelstein]

No asking price but I think in his head the owner is looking for ~$1,200. At that price, 5 years old, cost to move and risk of breakage during move, I think buying new w/ warranty begins to look attractive. Owner stated that the unit had not ever been serviced, since it saw minimal use. So I factor all that and consider $500 might not be unreasonable. Many folks simply overvalue what they are trying to sell.
Appreciate the feedback though.

 

[KinzeMech]

For $200, you can probably buy an engine hoist at harbor freight, and load it onto and off of a pickup by yourself. It's no cheaper than renting a uhaul or paying someone to move it, but you get to keep the tool when you are done.

 

[dirkelstein]

Now I like the engine hoist idea, because I have one of those. I never considered that it might be able to lift the compressor high enough. Off to YouTube for a search on how to.
Thanks!

 

[KinzeMech]

If you can get it for $500, get it, and fast, because that is the biggest bargain I've seen in a long time.

 

[Journaler]

.. Many folks simply overvalue what they are trying to sell.
...

Very true. As a buyer, you take a big chance with buying used from private individuals.

 

[KinzeMech]

I recently read a compressor-themed thread here where a guy had pics of his compressor, including loading it off the truck. He had a very heavy ratchet strap wrapped laterally around the tank, near to the top, and another strap tied into that one. Since he was not lifting from above the center of gravity, it did not hang straight, but if you have one or two people to help balance it as you set it back down, it could be made to work.

I saw a guy try to move one with an appliance dolly once. Don't do that. He didn't break the compressor. Didn't even injure himself, but he still made a very hard day for himself.

With the automatic drain on it makes a huge difference in price.
I am not so sure the rating of the HP motor. There are 3 different ways to rate hp and an aircompressor dose not need that large of motor. 110 volt can only run 2 hp. 220 runs 5 hp and and you can not run more without goin up in volts. I would check to make sure it is not 3 phase and 440 v.

$500 is a very good price. It might be a steal. 3 phase equipment is very hard to sell because the power companies will not run it to homes or small shops. It is very hard to get. Business is way off and that makes it even harder to sell. I have been dealing with used machinery for over 40 years and I never buy 3 phase unless it comes with other equipment and machines.

Be ware if the head needs rebuilding. Some of the kits to rebuild those large compressors can rund $250 and up. Then consider the age. If it is 20 years or older I would pass. Rust in tank. A tank good tank can cost you $400 to $1000 depending on where you buy it.

Check the phase. Something in your facts is not right. You can't run a 7/5 hp moter on 220. With that said they played games with hp ratings 20 years ago. All the companies got taken to court. Sears had 5 hp vaccume's Not possible.
Either the information you have is wrong or it was posted wrong. I would be very careful. My bet is that it is not the compressor you think it is.

 

[KinzeMech]

I routinely install and wire in 10HP motors on grain augers, running on 220V, single phase. It is most definitely possible. It seems like a lot of air compressors go to three phase once they get larger than 7.5HP.

Baldor makes 220v single phase up to 15hp, 60a draw...

 

[KinzeMech]

I have installed a 15HP grain bin fan. I think it used the baldor motor mentioned above. I don't remember the nameplate amps, but I do remember a 70 amp breaker was not enough to start the motor. It took a 100 amp breaker to allow the fan to start up.
You definitely do not want to run that kind of horsepower on 220V unless that is all you have available to you.

Horsepower is not limited by voltage, its limited by current in most cases.

Power = Voltage(Current)
7.5hp = 5,593 watts
5,593watts / 220V = 25.43 amps
Obviously, this is theoretical. There is nothing limiting 220V to any set horsepower though. What you will end up with over a certain horsepower is that you would need massive amperage. Hence you go to a higher voltage to reduce the amperage needed.

For instance a 15hp 220v motor would need about 51 amps. Go up to 440V and it only needs half as much.

That being said, most blast cabinets only require about 15cfm @ 90psi. Unless your planning to blast all day a 5hp should be fine. If you plan to blast all day long bite the bullet and buy a rotary compressor (thats big $$ though).

P.S. I would go with a Quincy over an IR. I know my next compressor will be a Quincy. They have the best duty cycle and are the highest rated compressors.

Thought I'd post a few pics of the add-ons. Low oil cut-off switch, after cooler and electric drain valve. The motor is a beast!

Pic of motor plate. Shows 230V/32A 1 1ph. So can I run this on 220V properly fused house circuit?

You will need to multiply motor current for 7.5hp motor per NEC 430.147 (29a) by 125% for you conductor size. 29 x 1.25 = 36.25. NEC 310.16 requires #8 copper wire for that amperage. Sizing breaker per NEC 430.52: 29a x 250% for inverse-time circuit breaker = 72.5, next size up = 80a circuit breaker.

Cord and plug must be rated at 140% of 29a per NEC 430.109 F = 33.35 so 40a rated cord = again #8 SO cord. Should you use a disconnect instead of cord and plug, must be rated 115% of 29a.

FWIW - you can get a IR 5 HP 80 gallon unit at Tractor Supply for $999 brand new.

[EOC_Jason]

The electronic auto drain is really nothing special, you can but them $100 new. The after cooler mounted on the belt guard is nice, several people have done DIY similar. That model goes pretty much $2,500 shipped from anywhere (plus tax for some)...

I would at MINIMUM before making an offer, check the OIL and AIR FILTERS... If you can plug it in and run it that is a plus too, make sure it pumps up and doesn't make any horrible noise. I have a friend that uses his air compressor so little, even after several years I looked at the dip stick and it looks like brand new oil.

$1,000 is a fair price for that model IR... Maybe $1,200 if it was in near mint condition.... Maybe $800 if it looks pretty worn or not taken care of.

GET LIFTING STRAPS from Northern Tool or Harbor Freight. Don't even think of trying to lift it with ratchet straps!!! Or if you have chains you can use those too.

You can rent a trailer if you don't have one, they even make one with a hydralic piston that lowers the deck to ground level so you can just cart things off & on.

Ok tell us how they are cheating. IR model 2475N7.5 7.5 hp 230V single phase.

I recently bought an Ingersol Rand and I was extremely dissapointed with the quality. The tank leaked in 3 places. The pressure gage plate popped off when I was unpacking it. The engine is made in mexico, the pump in india and the tires in china. It was advertised as made in USA by Norhterntool, maybe assembled,, but most of the parts are not made in USA.
I would love to return it, but what a hasstle.

 

[EOC_Jason]

IR of today is not the IR of yesteryears... You pretty much summed up their current production... it's sourced from all over... and not all over in a good way either...

 

[zkling]

Many folks simply overvalue what they are trying to sell.

And many buyers simply want something for nothing. Think of it this way; if that was your compressor and someone offered you $500 for it would you take it?

I would personally offer ~$800 and let him talk me up to $1000. My general rule of thumb for used equipment in average working condition is 1/2 the approximate new value, whether buying or selling.

In the $1000 price range there is a lot of quality industrial compressors on the used market, older IR T-30's, and my personal favorite the Quincy 3 series on horizontal tanks.

If it was me I would keep looking for an older compressor. They seem to be built much better (like most things) and run much quieter. I really like my Quincy 370 on a horizontal tank. Makes a nice quiet chuga-chuga noise. Complete setup that I have WAY less into it than $500. However it did take some patience to assemble waiting for parts to become available.

I agree with this. I also think that there must be different levels of IR

I am the tool/hardware manager at Lowe's. I have had 3 of the IR compressors come back in the last 6 months.
1 80 gal 5hp
1 60 gal 3hp
and one of the smaller ones on wheels

I purchased the 80gal for myself for $75(basically scrap). When the guy returned it he said the compressor was making a lot of noise. He had it for 2 weeks. I could see that there was some oil leaking from the seals on the compressor.

I figured I could up grade my 60gal tank to an 80 gal tank and maybe sell of the motor
I have a 60gal that was my dads 50 years ago. the 5hp motor he bought 40 years ago for $500 works great(and is twice the size of the IR 5hp). I don't know how old the compressor is.I did have to replace the tank about 7 years ago because the tank he had(horizontal) rusted through. I replaced it with a vertical tank
I got it when he passed away over 20 years ago. I don't get to use it much because I work 75 hrs a week and dont get to play in the garage much.

The IR 80 is still sitting complete in my garage waiting to be dismanteled.

The 60gal we had come back was having same issue according to the buyer. He had it about 3 months before it went bad. I purchased it for $60 and let a friend buy from me for $60 it to rebuild

In a home garage the IR will probably be fine. Using it in a business where it runs all day long......I would go find another brand

 

[dirkelstein]

Thanks everybody for the input. I decided to pass on this one. It is just too much of a beast and my love is for something a bit more "vintage".

 

[FThera]

The Model he's looking at has the T-30 compressor. The Tractor Supply compressor is not even cloase to the same quality. $500 for this onw with a single phase motor is a steal.

 

[marinusdees]

Rule of thumb. Good (working) used is worth half of new.

[camarotoolman]

Lean compressor over the bed of truck, pick up on the bottom up on to bed, no big deal. A strong friend would help, I think I moved mine by myself but can't remember.

 

[camarotoolman]

2nd. they are on sale @ tractor supply.

 

[Beaumont67]

Thanks everybody for the input. I decided to pass on this one. It is just too much of a beast and my love is for something a bit more "vintage".

^^^^ If it had the 2-stage commercial T-30 pump, I would have paid $1000 for it.

I have a 1986 or 1988 vintage 2 stage 80 gal horz. compressor with true 5 HP Doerr motor (with capacitor start - wired to 30 amp breaker, and rewired 8 gauge cord...replacing 12 gauge hard wire).
Unit previously used in restoring a VW's beetle every few years...decades later, after father passed and son relocated (across country) in new job...unit came up for sale and included a near new Sharpe water seperator.
- I waited 13 years to buy it for $750 and it just got treated to AMSOIL synthetic...beast still runs like new
- we used a 7 ft. steel ramp, took 4 men to push it up and into the bed of my 4x4 truck
Yes...extremely heavy.

2nd. they are on sale @ tractor supply.

^^^^ Another buddy of mine, a licenced body man bought a 1-stage / over-rated 5HP sale price $499 compressor ($300 off).
Would not even keep up to his D/A sander // flipped it and bought a used 7.5HP compressor (@ double the cost), out of a shut down body shop...now he has all the air volume, he needs.

Often, one gets what they pay for - mint vintage is usually better than a new (cheap) purchase today !!
(even at the same $$, without having a warrenty)

 

[Steevo]

The unit the OP was looking at is easily worth $1200 as it sits.
That is not a consumer-grade IR, like they sell at T/S or Lowes, it is a commercial-grade unit, with the 2475 pump, which is one of the best pumps made.
At 32A/230v, that is a real 7.5HP motor, and it won't be cheap to run, but it won't have any problem keeping up with a blast cabinet.

 

[Norcal]

At $1200 bucks I would buy new, anything close to 1/2 of new means it's time to buy a new one just for the warranty.

 

[78Bird]

if you decide to get it, I recently moved my smaller one, and took the motor and pump off.

MUCH easier, with those 2 large weights off the top the tank was hugely more manageable.

 

[shooting4life]

Lean compressor over the bed of truck, pick up on the bottom up on to bed, no big deal. A strong friend would help, I think I moved mine by myself but can't remember.

This is how my brother and I moved an 80 gallon and a 60 gallon compressor. Just get it close and lay the top down on the tail gate and lift the bottom up. It is actually more work getting it down then up since they are so top heavy.

I love this forum! I wish I'd have found it months ago; you'd have saved me a lot of time. So, here's my dilemma: I'm in the market for a 5hp, two stage, 60 gallon vertical compressor, and have found out from Aircompressorsdirect.com That Quincy compressors are the best. It'll be for general shop support. However, I can't find a local supplier in the Seattle area that carries the Quincy model I want. Second best are shown as Ingersol Rand, and I've found a supplier in Kent Wa. The problem is, the compressors weigh between 400 and 450 pounds. Why is it that one can buy a mattress and they'll deliver it, set it up, and take the old one away - but all the air compressor outfits will do is what the on-line suppliers will do - send a freight truck and, for some additional money, they'll provide lift-gate service, drop it off on your sidewalk, and say "good luck?"

I've built a storage shed on a concrete slab in my backyard behind my garage, which is where I want to install the compressor. The idea is to pipe the air into the garage for shop use and to support my sportscar project, but without having to sacrifice the space and deal with the noise. The problem is the compressors weigh between 400 and 450 pounds. So, my plan is to hire a moving company with a couple of movers and a truck, go pick up the Ingersol Rand and have the guys help me muscle the thing across my yard to the storage shed. And then, since I've been planning to eventually get an engine crane to help with the sports car anyway, I'll just get one now and use it to help install the compressor. I'll use it to lift the compressor up, remove the pallet, mark the holes for drilling with a hammer drill, and then install the compressor with anchor wedges and vibration insulators.

So, I figure that since the compressor's about 5'9" tall, I'll need to lift it up about 6 inches, and add another foot or so for straps or a chain; so I'll need an engine hoist that can get up to at least 7 ft, 3 inches.

It should also be a nice one, able to be broken down or folded up, and should have lockable wheels. Any recommendations? I've been looking at the Model 3580B here:

What do you think?

I just pivit mine when moving it. No need to lift the whole thing at once. You are over thinking it. You could rent a lift gate truck and move it yourself with a buddy. Just lean it on one side, pivit, set down, lean back up pivit, set down. Does not take very long.
Lifting the 6 inchs will be a challenge but nothing two men cannot do. Like I said above, my brother and I moved an 80 verticle in the back of his short bed truck and pivited it into the garage.

 

[Kevin54]

It's not hard to move a compressor. Tip it onto the tailgate and a couple guys can slide it in. In hauling it, you can lay it down. Just make sure it sets upright for a day before firing it up. Never had a problem yet

 

[etijsma]

I got my 2475n 10 years ago or so from home depot for $1600 back when they use to sell them. I love this thing and would never considering getting rid of it.. like another poster had said if you offered me a silly amount that conversation would end.
