Eastwood Master Blaster Dual Abrasive Soda Blaster is rated 3.2 out of 5 by 29.
Rated 3 out of 5 by from Good, but not great When its working- it works fairly well. I had several blockages, I needed to run an industrial dessicant to get it running smooth and moisture free. Switching from abrasive media to soda is nice and smooth, The clamps and valves are poor quality, I expected better from Eastwood. It is slightly over priced. If I had to do it over again I would try my luck with some Habor Freight equipment- but I have been dissappointed there before. I am satified but expected more. The face shield/hood they supply is garbage- thin, flimsy, poor protection. If you value your eyes buy one of better quality. I rarely post reviews, but this needed to said. DM

Rated 2 out of 5 by from Unfortunately it is difficult to use. Since I started using this blaster I have had constant problems with getting media to come out on a regular basis. It works for a few seconds and then I have to keep shaking the unit to get more. Then other times there is so much media coming through that the hose is to full and it just pours out on the ground. Had to replace one valve already and I believe another is bad as well and I have only use the unit twice since I bought it in May. Very discouraging. I have been using Black Beauty and soda to strip paint off an old hand water pump. Never though it would be an all day job.

Rated 1 out of 5 by from Dual Blaster Piece of junk. The location of the feed valve is terrible and poor quality, you need 3 arms to use as the sand does not flow. I initially wrote Eastwood on some design recommendations and never heard back. I now have my blaster on a roller cart which elevates the tank so I can work the feed valves, I purchased a concrete vibrator and fixed to my stand to give a steady vibration to help the sand flow. If I had to do again -- I would not have purchased this product -- overall extreme poor quality in components and construction.

How large an air tank is recommended? While 90 psi is the minimum will 125 psi allow for good operation?

Asked by: Roger47
You will just require a compressor large enough to produce 10 CFM @ 90 PSI minimum.

I have had the dual blaster for some time now but this is the first time I have had a chance to use it. Using the soda I had the same problems as those giving poor reviews with it blowing out a large amount then having to shake it. Is there a fix?

Asked by: RayCar
It sounds like you have the mixing valve on the bottom of the unit wide open. This will cause what you are describing. Make sure this valve is no more than 1/4 of the way open.

Is a 8' x 1/2" hose included with the dual blaster, or is that the maximum length hose that can be used? 

Asked by: tonycvfd1
The 8 foot hose is included with the blaster. The use of a longer hose will increase the CFM consumption of this unit.

ground glass can be used and sodium bicarbonate one in each tank? I want to clean wood thanks

Asked by: alberto c
This product is designed to have one blast media in each tank. So yes you can run ground glass in one tank and Soda blast media in the other tank. This will allow you to choose which media to use with the flip of valve.
