Sand blaster machine

[diegom6]

Hey guys,

I'm looking to buy a "portable" (not cavinet) sand blaster machine. I have seen some on internet but they seem to use only air pressure from your typical air compressor from shopp, but requires 125 PSI to work.

I want a medium duty machine, to clean up rust from some cars we work in the body shopp and not delivering them to a sand bblaster shopp or similar to get the jod done.

Where I bought my turbos-repair them, they have a cavinet sand blaster to clean up the turbos, but it uses a electric motor rather than air pressure I think.

What are the options out there, anyone that can point me in good machines?

I heared as well, that exist a sand blaster that use iin conjunction with sand, water or somethign similar to avoid spreading all the sand in the palce when working in a vented area (floor) of the shopp so it doesn't create "dust" nor sand all over the floor but obviusly once it's cleaned up, it must be coated with something to prevent the slight rust come over while drying the metal surface.

Any tips welcome

Thanks

What air pressure/cfm do you have available? That's going to limit what you can efficiently use as far as sandblasting equipment.

You say you want something portable. A lot of the cabinets are portable... or are you talking about a gun with a hose that you are free to move around?

Harbor freight has a gut with a small tank for like $15, it still will require a good bit of CFM's though, and you will be refilling it with a filter every minute or so.

I'm in the market for one as well, and not sure what direction I want to go yet.

From experience I would say get a sand blaster on wheels from harbor freight then get a good gun because you will hate not having a gun.

The gun is the most important part because it controls the flow of sand and air.

Well this is how I blasted 3 cars with no problems, I went with two water filters after the first car...

I wonder if Harbor Freight has stores in Peru?

Do yo uhave a link?

Our pressure system it's about 90-100 PSI, no more and CFM, I'm not sure.

The parts I intend to blast won't fit for sure int eh cavinet, frames, body panels, etc and other stuff, that's why I need a portable unit.

What you mean with the "two water filters" stuff?

Luke, we don't have that over here, but I can buy it from there, and make the stuff be shipped to our warehouse in Miami.

Thanks

You have to be careful with a sandblaster, the sand particles hitting the panel create a LOT of heat which can warp large unsupported panel easily ( think hoods, roof, trunk and door ).

Thanks for the tip and it's what I kinda thought earlier, but no problem, we will take car eof that.

Now, I would just find that machine and I'm set.

Harbor freight ships internationally iirc.

You need to find your CFM rating before deciding on equipment, even if your PSI is good enough. It's like voltage/current/resistance... you can't get one without knowing the rest. You may end up with a gun that will only last 5 seconds then having to wait 30 seconds for pressure. That's no fun. You may realize that you'll need to upgrade your tank and compressor. Sand blasting taxes the air system pretty good.

He was referring to water filters that do just that... filter water from the air. If you get water in the system, you get clogged up, and spend the next few hours trying to clean it all out.

You can also look at soda blasting for less heat on sheet metal.
