I have a 220 volt 8 horse compressor with a 10 gallon tank. So I concluded that I had a sufficient air source to make the unit work.
When it arrived, I went to the local lumber yard and purchased large grit sand specifically prepared for sand blasting. I quickly discovered that the screen on the Campbell unit would not let the larger grit sand pass through it. So I dumped 400 pounds of sand under my grand kids playground system and returned to the lumber yard. This time I skipped the medium grit and went for the small (fine) grit sand. Four 100 lb bags were loaded and off I went.
This time the sand passed through the screen and the blaster was loaded. With everything hooked up, air at 110 pounds, goggles and breathing mask on, I began the cleaning of my chairs. Unfortunately, the unit barely worked. Some sand erratically came out, but mostly it was just air. To wrap this up, I worked with the unit for several hours, trying everything I could to get the sand flowing. Finally, 400 more pounds of sand went to the grand kids playground.Read more ›
Yes, there is a small hole in the hose connector where it goes into the main body of the container. Do not cover this hole with the hose when blasting with dry media, or it will surge. I fought this for a couple of hours before I thought to read the instructions more closely, so my bad. For those reviewers that dinged this as a negative, I found almost immediately that all you have to do is turn the connector so that the hole is pointing straight up, and almost nothing spills out when you stop blasting.
Several people have mentioned the importance of a dry air supply, I will actually disagree with this to some extent. It's very important to have some kind of dryer or water separator on the airline, but I have found that my air supply is just a little wet (now corrected), but since the venturi chamber that draws in the media is so close to the nozzle, there's really not much opportunity for plugging in the very short path where dry media encounters slightly wet air at a pretty high velocity. So no, I have not personally found that bone-dry air with a 40-below dew point is a strict requirement, but I do still recommend that the air be as dry as reasonably possible. It's a best practice for maximizing air compressor life anyway.
I'm using it with a Campbell-Hausfeld 60-gallon 3.7-HP compressor, which puts out about 10 cfm at 90 psig. So far I've kept it at about 100 psi, but I tried it around 80 psig and also around 110 psig and it still worked well. Once I learned the proper use of the hose connector, I've found the feed to be steady and strong, and the overall removal efficiency to be excellent.Read more ›
I read all of the reviews and compared this to other brands of similar price. I am not able to use the sand blaster yet. Read on...
In its favor was that it arrived one day early, it was packaged okay, assembly was easy enough and I like its size for the job I'm doing. Not in its favor is its design, choice of materials and just okay owner's manual.
MATERIAL HOSE CONNECTOR
The first thing was trying to attach the material hose connector to the bottom of the unit (Hopper). It is made of common plastic and the nut that threads onto it is made of metal. Because the hose will put strain on the connector, the connector has to be tightened firmly. As I tightened the hose connector and inside nut together the plastic threads on the connector stripped down immediately and wouldn't tighten any further. So the connector spun around in the drilled hole.
The second thing about the hose connector is that it has a hole drilled crosswise into it just behind where the connected hose stops. Its purpose is to let some air into the stream of material from the hopper as it passes into the hose. The instructions say to cover the hole with the hose when using the sand blaster for spraying liquids.
With the hole uncovered as it says to do for dry materials blasting, I poured some material into the hopper just to see what would happen. The material was medium grade glass beads. It immediately started leaking material out the bottom in three places. One was the hole in the connector.
WHEEL AXLE ROD
The other two material leaks were coming from the holes in the bottom of the hopper.Read more ›

Contrary to other criticisms of this sand blaster I found it to be a very good machine for the purpose to which it is intended? Read morePublished 5 months ago by Mark F

With my compressor it hardly work at all, just another very bad investment. Would not recommend to anyone.
I will try to sell it.
This is a gravity fed blaster and it does not work very well. I used medium slag abrasive and it did not feed into the hose very well. Read morePublished on February 16, 2013 by don-john kulish
