Its a slurry blaster, there are several on the market. In looking at their diagram it appears to be a simple adaptation of a dry pot where water and media are added then the pot is pressurized with air. On a true slurry blaster the pot is pressurized with water which has several advantages.

It looks like a sand storm design.
It has small pipe work you need 1'1/2 pipe work and a 1'1/2 ID blast hose for good performance.
I would put my new pot up against it ant day.
I use course glass and I haven't had any complaints about dust from that.
Pics of my new pot will be up soon.
I don't know what pressure I'm getting at the nozzle but it takes some hanging onto.
I get 150psi at the pot.

I don't know if this link will work, but it's me using our WIN nozzle on cement block.

After watching the dustless pot, and how much water it leaves on the surface, I think mine looks to use about the same usage of water.

I metered the water into a gallon jug ( no air psi) just water and it only filled the jug 1/2 way in a minute. 2 qts a min wide open.
It can be adjusted at the nozzle with a ball valve for less water usage.

The best part is that I can turn the water off at the nozzle and blast dry if I need to, then turn the water back on.

Ausi, nice! looks like you got a psi hold! :thumbsup:
When I switched to a psi hold unit, I saved so much grit and time.
Wish I could have 150 psi on some jobs.

Looks great! :thumbup:
The psi hold is great.
The Thompson valve II is a fantastic piece of kit.
My old pot was a clemco unit that I changed everything over to 1'1/2 pipe work.
This pot was a bargain it is the same as a shmit with all the quality components but at quarter of the price.
I am going to install an SMC regulator and a ball vibrator to help things along.
The metering of abrasive is so precise on this pot I think you could even shoot soda with it.

I agree, The pressure hold is key. I have not switched over to electric deadman yet though.
Electric deadman's don't work well with dustless/wet blasting systems.

On the DustlessBlaster the system is nothing but a wet sandblasting pot that dumps a ton of media onto the job.

The Farrow System and the GeoBlaster use only 1/5th of the media to do the same job.

If I was looking to buy a dustless / wet abrasive pot those are the only two I would consider.

The sand storm gear doesn't handle course abrasive very well either.

Pressure operated blast pots provide better performance then siphon type blast pots when you use big air.
The sand storm designed pots also have trouble metering fine glass.
I had one of those small sb100 pots I would have liked to try it out as a wet blaster.
The sand storm pots are a great soda pot.

If you want good performance you need big pipe work and a pressure hold pot.
A large diameter blast hose is also a must.
An after cooler that is rated higher then your compressor is also a good investment.
The older ones with the small steel tank work great but they are hard to find.

It has taken me awhile to get a system I am happy with.

If you have the money to dump on a wet system that's great.
But if you have a dry system already, and don't want to spend more money for a wet pot,

Try a "WIN Nozzle" it's a few hundred dollars, hooks on the end of the hose and is a direct injection of water into the air stream.
Can be adjusted for a little bit of water to a lot,
And you can shut the water off, blast a bit then go back to water in seconds.

Just saying.....

I'm in Maine and it's 10 degrees out, water pots don't work in winter up here.

It gives me a option to use with my dry pot, for less money!

Jim, that is a good suggestion for a contractor that needs some wet functionality. Having used both a water collar and a true slurry blaster I can say that the blast experience at the nozzle between the two systems is pretty different. The slurry blast is less acute, more like an abrasive fog machine in some ways and it cuts a gentle, wide swath with low media usage. Both useful tools but different. Imagine shooting with a #8 nozzle at 40 psi . . . its pretty cool what it does.

The good thing with the WIN nozzle is its used with a dry pot but gives versitily with the wet slurry. It does not work like a water
Ring that mists around the grit, it mixes in with the grit at the nozzle, giving it more of a mix. I've never used a rig like you guys got, but would love to give it a go at some point. The only thing I like about the win nozzle is I can turn off the water instantly and blast a section dry if I need to. Then turn the water back on to keep going wet.

Do you have to drain the pot when your done?

The WIN sounds interesting. Yes, our pots are filled with media and water and kept pressurized with water. At the end of the job the pot is drained of remaining media and water, the media comes out first (goes into a bucket) and then remaining water is disposed of on the ground. Pot has quick disconnect fittings at the bottom to make it simple.

Actually I leave my pot with water and media in it after a job.

Main reason is it adds tongue weight to the trailer.

Most jobs I do use medium 40-70 glass and set-up time is faster if the pot is full with media and water when I get to the job.

Also on winter mornings when the temperature is below freezing and the job is less than 30 minutes from the shop I fire up the compressor and leave it running while I drive to the job... reason being is the heat exchanger heats the pot and keeps the water lines from freezing.

This way I can start blasting within 5 minutes of arriving at a job in the morning... and I don't waste time filling the pot with media and water at the job site..


At the end of each day during the winter I drain my water tanks and pump windshield antifreeze into my Farrow System with this quick winterizer system I put together so my water lines don't freeze on the way back to the shop. :thumbsup:
