I bought a truck today loaded with equipment. Its a 2008 Mitsubishi fuso with a 12' box 12k miles. It has a 425 compressor with moisture seperator and aftercoolrr only 200 hours. It also has a clemco contractor 150 blast pot. I originally bought the truck just for the compressor but after some research its a little over kill for what I'm doing. I only need a 185 compressor. And I can buy a new 185 for half of what this is worth. Pm me if anyone is interested in the pot truck or compressor.

Thanks,

Rob

Keep it you will be able to take on bigger jobs.
Sand blasting is like the **** industry, SIZE MATTERS.

I stared off with a 185, quickly learned I needed more are. Hooked two 185 together for a while,
Now I bought a 260 - 100 psi
I'm loving the extra power on most jobs
But would love the ability to go to 150 on some commercial jobs.

I to only thought 185 would be enough when I started.

You can buy a air regulator for a hundred or so to cut the air down!
And when you find your self on a job that needs two blast pots running, or need to run a bunch of air tools while blasting, or getting into
Air run fans and motors, use the air for a vacuum ..... It's endless

You have much more than just a " air compressor" that's to big!

PS: just paid 13,500 for a 2008 ingersoll with no after cooler 800 hours.
It sells new for over 20,000!

Yours is newer, and it's twice the size. ;)

My 260 burns the same as my 185 did.
Reason:
My 185 would run wide open, full throttle to keep the blast hose at 75 to 80 psi with a #7 nozzle
My 260 runs at just under 1/2 throttle, keeps my blast pot at 105 psi
(Even with the psi drop through the air cooler) with #7 nozzle.
Now with the 425 cfm? I imagine it’s going to burn some more fuel, but it would
Just be at an idle,
what you got to look at is when I first started, I expected to just be doing boats and cars.
In a very short time (and I’m in Maine were money and jobs are far apart)
The variety of jobs for me boomed, and we do all sorts of different type jobs, and have been getting into commercial building too.
I could not do this type of blasting if I didn’t have a big CFM compressor, I still at times wish I had 150 psi to blast some things.
I at times, cut my air down to 30 psi to blast wood, up to 100 for dump trucks....
He has a great deal there, with room to exspand.
Being able to cutting the air down, or let it rip for bigger jobs give’s a huge range to blast with.
If after a few years it’s not working out, sell it…..
The set up he has there, I’ve been working up to in 5 years!

Dryer,

Thanks for your help and honesty. You've been a big help since I first called u about a month ago. I didn't expect to cowboy up and get a compreesor that big right away but I came across a great deal that I couldn't pass up. If I decide to keep it do u guys think I'll need another after cooler and moisture separator? I realize there's one on the compressor but is that enough? Just wondering because all the pot manufactures sell a seperator and an after cooler. Seems to me the ones u buy from the air compressor manufactures are much cheaper. Maybe they aren't as good?

I had an aftercooled 400cfm at 150psi unit that worked great at normal temps.
But it gets to 45 degrees + here in Australia and then it struggled.
In fact it killed the compressor.

I would think the ones on the compressor would be enough. Mine are separate from the compressor.

Anyone else got input on compressor after coolers that are built in

Are they good enough alone?

113 should not have killed it. Cooling veins was probably clammed up with oil and dirt that kept it from cooling properly. Here in Alabama we've even ran a water hose into the radiator to keep em' running on hot days. These compressors radiators needs a lot of attention. Keep em' clean! And if I wanted to get rid of a 425to buy a 185, I would have to have my head checked.

Ausi, would it be the engine fan that didn't keep up with your 400? I don't think the aftercooler has an affect on the engine temp, just the air that goes in to the pot?

The aftercooler on the compressor was ok on a mild cool day but if the humidity got high or if it was a really hot day it would lose efficiency.

I would say it alone removed 70% of water from the compressed air lines.I haven't investigated why my 400cfm unit died but the day it did it it was 45C and you could have fried an egg on the top of the compressor.

I am interested in buying the Compressor. Plase keep me in mind if you decide to sell it.

In all honesty, you should keep it it or trade it in for a Unit that you would like.

But if you are going to sell it I would like an opportunity to buy it.

Thanks
