The whole point of getting the water in by the mixing valve is giving it time to mix with the grit before it comes out the hose.
I've been playing with this for a while.
Just didn't go far, money and time big factors but I'm glad to see multiple versions of this by you guys.

Keep on inventing.
Cause even with any blast pot, wet or dry
Someone had to have a idea to mess around and try building something new.
You think geo blaster just built their system over night.

I like str8jackets water induction point, I think it would help blast hose longevity.

Greetings to everyone,

This is my first post and I would like to say that I am on several other work related forums where discussions are about my other work passion and the level of professionalism, courtesy and helpfulness displayed on this forum by all the contributors is quite honestly amazing and puts those other forums to shame. I am so tired of the "handbag swinging" and "eye gouging" on the other forums and coming here to read and research this subject makes me excited to be getting involved - hats off to all you gentlemen.

I am new to this line of business and have been "pushed into it" due to circumstances but as I stated, I am getting more and more passionate about this new development and the level of skill required and how much experience plays a role in delivering the best product is a refreshing challenge. I can't wait to get going.

I have a soda pot and multi-media pot on order (local supplier) along with a blast cabinet and fixed installation compressor. Due to the expense of purchasing a mobile diesel Compressor, I will be hiring one for the bigger jobs. I will post pics once delivery is done. My goal is to get going and as revenue improves, I would definitely be looking for a 250cfm mobile compressor and possibly (depending on finances) a Farrow/Geo wet blasting set-up.

@ STR8JACKETS - I know you have only had your mod on your equipment for a few days but I really like the idea of an interim bolt on system to convert the multi-media pot into a wetblasting system. Would love to hear how it is going and how it compares to the established wetblasting systems in terms of production, water/media useage and clean-up headaches. I have my doubts about the water nozzles after watching numerous videos and reading a lot of expert opinion and I think you might be onto a winner here.

Thank you all once again for a great read and hope that someday I can also contribute.

Guys,
I read whole thread what took me some long time... it's all about battle between DustlessBlaster from MMLJ vs. GeoB+Farrow.

I have SodaBlaster pots and Dustless Blaster pot from MMLJ. Which is same, but first one include also cooler and water separator. Have SB-500, SB-150, and DB-150.

I know how they are made, how they are working. Got drawings, on their website you can find some animation how it's working too.

You already wrote something about them here too, but...
nothing about how's made GeoBlaster or Farrow Blaster. I know that first one is faster, better, etc. so please focus on Geo while answering on my questions.

How is it working ? (in technical way)
Where are differences ? (in technical way)
Could you make some photos how they are made ?
How air is moving through the machine and where and how it's mixing with water ?
What makes it so special ? (in technical way)

Forget about results, I already read your praise how it's great.
I want to know how it works from a technical point of view.


Another thing is what guy with one post already wrote - address of GeoBlaster company. Wow, I made my searching and there's no address on website - anywhere ! Even tried to "who is" their domain - no results :( This isn't PRO.
Already sent them 2 emails with inquiry, but any reply :blink:

After weekend will try call them, maybe somebody pick up my phone :thumbup:


Please do not understand me wrong. My post isn't to discredit any of these companies, especially GeoBlasters.
I'm very interested to buy a machine from them, but need to know something more. Prices too :laughing:

Well here goes the make-up of the dodgy add-on water injection system I’m running. :jester:
str8jackets, your air supply inlet coupling is much too small ! I mean that one on the cooler to connect hose from compressor to sodablaster.

It cannot be smaller inner dia. than inner dia. of blasting hose. For SB-150 it's 3/4". So, use always at least 1" air supply hose or bigger like 1.25".

You'll lose a lot of pressure cause of that. For example, on each 340 feet (100 meters) you're loosing about 30 psi with 1" inner dia. hose than using 1.25" hose ! That's a lot. Moreover, with 0.75" inch hose you're loosing even 150 psi !!! That's huge !

Good spotting Chuck! I had it hooked up in the workshop so I could use the wet air seperator before my air reg when spray painting. I don't normally have that on when blasting.

First I don't work for either GeoBlaster or Farrow System and there's a lot of proprietary stuff in both the GeoBlaster and the Farrow System that I really shouldn't disclose because of patent issues on each system.

If you want to know more about the GeoBlaster both John's and Wade's cell phone numbers are listed on the contact section of the GeoBlaster website, but it's the Easter weekend and I'm sure they're celebrating Easter just like the rest of us good Christians.

The big difference between Dustless Blaster and the GeoBlaster pots... is that one pressurizes the void above the slurry mix with air from the compressor while the other pressurizes the slurry mix with a high pressure water pump that pressurizes the void above the slurry mix.

On the dustless blaster the air chamber above the slurry mix acts like a big AIR SPRING compressing and rebounding as you blast meaning the media flow is always changing and is extremely hard to keep consistent... usually the operator just turns the media up to compensate for the air spring which means you're going to be dumping a lot more media out than what is required to do the job.

On the Geo Blaster and Farrow System they both use water to fill and pressurize the chamber space above the slurry mix...SO THERE IS NO AIR SPRING INSIDE THE POT... water is hydraulic and does not compress at all so the media flow is always constant and super easy to adjust from just a little bit of media to a lot media or in between with just a slight twist of the knob... also both the GeoBlaster and Farrow System you can also add water at the exit point of the pot making your slurry mix flow even better....bottom line you have a lot more control for both media flow as well as dust control.

Both the GeoBlaster and Farrow adjustments allow you to fine tune just about any type of media you choose to use (as long as it sinks in water) within seconds and it's always precise and easy to use.

fine tuning

We have used the Farrow System to blast water tanks 100' from hwy with great success. These are situations where enclosure is expensive and time is the motivator.

We took off 14-19 Mils of epoxy at a rate of 35sf per hour - had issues with the primer.

The farrow will allow you to fine tune media and water - like stripping paint / working indoors.

Holdtight102 is an issue as it is pricey.

Guys, remember to check for lead (Pb) before blasting: Lead Check swabs work ok. Cheap and easy to use but are questionable on the low range. Chip or XRF are better.

We are looking for a used farrow or comparable unit.

Geoblast

Whats up fellas! I've been reading all the post about the wet blasting system for some time now and I am thinking of purchasing the Geoblast.

Let me give you a little background. I used to be in the sandblasting business for 16 years. Got out a while ago but still have my equipment. I am thinking about getting back into it and am asking for some thoughts about how the business is today.

I'm going to try it part time in the beginning and see how things go. I really like the concept of the wet blasting instead of the dry. I still have my Clemco 600# blast pot and also a plastic media machine. all ran by an Ingersoll Rand 375 compressor. Any input would be greatly appreciated.

The machine!

Here is the machine men, 40,000 lbs per square inch it will strip anything- no grit required .If anyone is interested I will post a video of it in action.It is being used to remove rust-corrosion-paint on a stainless steel rail car.

looks like water jetting, how do you deal with flash rust ?
i've been looking at the gardner denver machines... and they look VERY expensive !

Other problem is it will not leave a profile on steel. Only exposes what is already there if there is one there.
