Eastwood Master Blaster-Dual Blaster is rated 3.2917 out of 5 by 24.
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.

Rated 2 out of 5 by from Not for the majority of home garages I purchased this about 2 years ago and have used it for various projects. The specs state it requires 10 cfm at 90 psi. My compressor will put out over 12 cfm and go up to 150 psi however it really doesn't have the air behind it to make this blaster work well. It will do OK for small projects but don't expect to use it on a car restoration especially on rust or more than 1 coat of paint. Avoid it unless you can get a lot more air through it than what Eastwood states.

Rated 3 out of 5 by from wasted alot of time and $ I read the reviews. I watched the videos, My compressor is 125lbs/15 CFM. I have never been able to get the Dual Blaster to work consistantly more than 10 seconds. Too many variables which are constantly changing: Throttle valve, media valve, available air pressure - as pressure goes down in your tank, the valves need to be constantly adjusted. Ambiant air humidity is also a big problem. I finally took my sheet metal to a pro - He chuckled when I told him I had tried to use Eastwood's blaster, Said I was one of many.

Rated 1 out of 5 by from will not work at all. I bought the master blaster and, I cannot get anything to wwork on this equipment. I have it loaded with soda and media. nothing comes out the hose. the gauge is stuck on the wrong side so I can not tell the preasure. It would be a great system if it worked. I will be in contact with Eastwood . I hope they will make it right.

Rated 4 out of 5 by from Good small job blaster I upgraded my compressor dryer prior to using based on other reviews so no moisture issues. Took awhile to tune flows but was able to get a repeatable setting for both soda and grit. Did not try to mix medias and doubt I ever will. I used the lower cost 60/40 Black Diamond media without issue. Small pots make it easy to store but not suitable for larger jobs. Did what I needed it to do well. A good tool.

Rated 4 out of 5 by from Dual Soda Blaster A big thumbs up! Some fittings had been lost in transit to England(Customs no doubt) but were easily replaced. Assembled kit quickly, followed the instructions, and got great results in seconds of use on vintage BSA Motorcycle engine cases (that had more than their fair share of heavy hand painted layers) Having a good supply of air is very important so have upgraded to a diesel compressor for more steady pressure and cfm. Very good addition to workshop, great service from Eastwood Too! Buy one!

is that possible to work with soda in two tanks - like micro soda in 1st tank and heavy duty soda in 2nd ? or its like soda and grit only ?

Asked by: mark29
The dual blasters dual tanks were designed to use soda in one tank and abrasive media in the other tank. Using soda in both tanks will clog the unit.

what does it mean : 60 grit or finer media. Ive juts bought Eastwood Master Blaster-Dual Blaster but Im from Europe and I dont get what does that measure means - can U tell me what kind of media is recomended to the other tank ?

Asked by: petePA
60 grit is how coarse a media is. Lower the number the more aggressive the media is. All media (aluminum oxide, silicone carbide, soda, walnut shells, glass bead, etc) is labeled with how coarse the grit is. 1 tank is for media and the other is designed for soda.

Car you put in regular sand

Asked by: fluke
No regular play sand is too aggressive for the valves and lines of the unit. We recommend a 60 grit or finer media.

In regard to the dual blaster, you don't mention how many pounds of soda or media the tanks hold, i.e. 100 ld, 200 lb

Asked by: hayseed
Each tank holds 100lbs, but it is recommended to not fill more than 3/4 full for best operation. On very humid days, only filling 50% is recommended for each tank.

For using a dual blaster on a vehicle restoration, what would be the average amount of each media (soda for the body, coarser for the frame, etc) needed to strip everything down to the bare metal? Want to make sure to have enough on hand before starting.
