Well, the boss has had it with the setup we've been scraping by with up till this point, and told me to chuck the existing mess in the garbage. We've been running a homebuilt 55-gallon drum made into a bead-blasting cabinet, powered by a Craftsman 60-gallon air compressor. The compressor gave up the ghost, and he's using it as an excuse to can everything and start over with something more along the lines of what we need to operate. The drawbacks of the old system were:

- barely enough power to operate, it would have a few seconds of powerful blasts but you'd have to stop for a few seconds to allow it to power back up again
- the 55-gallon drum of a blasting cabinet had only a small amount of space in it, so we could only use it for smaller parts. The lighting inside was bad, and the beads wouldn't drain to the drain port well and you'd often have to take the rubber glove and manually move the piles of beads to the center for draining into the system again
- no filtration of the beads and associated dust, the work area inside the tank would often be so bad you couldn't see the work, and we'd have to change the beads often

We have the money to replace this mess with a new unit, and we want to do it right. We need a good recommendation for a combination of a bead blasting cabinet (purpose built, not another drum), a suitable compressor, and a vacuum bead/air filtration unit to remove dust and debris from the bead stream. Unit must be powerful enough to be used in a production environment, with up to 100% duty cycle (entire 8-hour shift) with the trigger down and no loss of air pressure. Pressure must be adjustable on the cabinet side, so we can pressure down and do softer metals like aluminum and brass as well. Big interior work area so we can get bigger parts in there. Nice big viewing window too.

Any help from you gents in a recommendation is appreciated.

What power do you have available?

240VAC Single Phase or 3 Phase 208, 480 or 600 (575) VAC?

That will make a big difference as to what equipment is recommended.

Trinco Dry-Blasts: http://www.trinco.com/leftframe1.htm

In my opinion, these are the best - We run 3 of these continuously for 8 hours a day. We have two of the 60" wide ones and a smaller 48" one. These are commercial units made for the rigors of non-stop production work like our coating shop. One plus of these over some of the others like TP, is the fact that the top hinges back to allow very large items to be placed in the blaster - bigger than can get thorough the side door. Here is a pic of one of the 60" units in the blast room:

I bought one of those 60" trincos with the dust collection system, but I have not set it up yet. Of course mine is missing a few of the important parts. I figured for $1500 I could buy the rest and still be less than the $7000 price tag of a new one.

To the OP, you will need a really big compressor to run a cabinet continuos for 8 hours. The trinco needs 100 cfm to be run like that and a minimum of 45 cfm just to limp along with the smallest tips. I am setting up a a big quincy that has two heads, I am still not sure if I am going to run a 10HP and a 15HP or if it will be a 10HP and 7.5HP. You need 25 HP to get 100 cfm and 15 HP is the biggest single phase motor you are going to find. My guess is you would need a big rotary screw and I don't know if they make large ones single phase. You are probably looking a 15K to get setup with new equipment, used price would depend on how fast you need the stuff.

Strouty is right - you need some serious air. Guess I should have clarified that we are running a 40hp Eaton Rotary Screw Compressor and its maxed out! - Looking to upgrade to 60-75hp. These units take a lot of air, but they get it done. In the grand scheme of things, time is money and the faster we can blast, the more money we make.

I used to run a larger HF blast cabinet with a Craftsman "Pro" compressor. It was painted black and had the gold lettering so I figured it had to be good, right?

I eventually shot a piston out of the side of the block of the Craftsman compressor and found one of the rods in 3 pieces. Aside from loosing the motor off a $599 compressor, it was pretty spectacular.

I called a local industrial compressor company. They not only sell new but refurb units. I bought a solid cast iron, oil bath heavy duty unit for half what I'd have spent new. Took 3-4 guys to unload and move it off the truck. New pump and rebuilt motor. Has yet to even hiccup. Not near as annoying to hear run as that POS Craftsman I had either.

Figure what size compressor you need and add half.

Then call TP tools. If you are not using one of their guns on your cabinet you don't know what you are missing. Tell you boss to bite the bullet and open his wallet. He'll never look back when production increases.

SCREW compressor . . . you're in the BIG time now !!! ;)

Massive CFM capability and they just keep going and going. Probably could get re-furbished used screw compressor if your budget won't cover new one.

Good luck and post up pics of the Solution !!

Too bad you're on the wrong coast. I have the perfect commercial cabinet for you.

And yes, as far as air compressors for a blast cabinet, some's good, but more's better and there's no such thing as too much volume. Spend the money on the compressor and supply lines first.

I'd get a DeeBlast if money was no object. Get a clamshell cabinet with a pressure pot built into the bottom. Pick a compressor to match the gun requirements.

Did you find one? I have a surplus Trinco deluxe 48x24sl/450dlx in Greensboro. It has the three piece dust collector etc. Not far from you at all.
