Eastwood B20 Benchtop Blast Cabinet

Product Overview:


An affordable way to media blast parts without taking up much room in your shop. The smart, space efficient design of this bench top media blasting cabinet really can’t be beat.

  • Affordable way to media blast at home
  • Space efficient bench top design
  • Durable powder coated cabinet
  • Holds up to 25 lbs of blast media
  • Holds up to 55 lbs of parts
  • Upgraded Bright LED Lighting for Better Visibility
  • High quality gun with replaceable tips
  • Needs just 7cfm @ 90psi
  • 19in x 15in window lens
  • Full window sized tear offs
  • Fits in just 24in x 20in space

Use with 60 grit or finer blast media.

Use of Walnut shell media is not recommended.

The whole hinged top of the cabinet is both the access door, and the view window. This gives you much greater access to the inside then even some full sized cabinets. Meanwhile, you look down at your work through a big 19 inch x 15 inch screen, with full sized tear off protection (5pk #30770). Dust control is handled by hooking up any shop vacuum to the cabinet, or use it in a well ventilated area with no vacuum. The whole cabinet will take up just a 24 inch x 20 inch space in the corner of your work bench. That means you have nearly 3 cubic feet of work space to blast in. Just about any shop compressor can run it too; it needs just 7 cubic feet per minute at 90 pounds per square inch. The included high quality gun will work with a variety of media, and has replaceable ends for years of usage.

Rated 5 out of 5 by from Works pretty well Bought this cabinet to clean parts for an antique car restoration. It works fine so far. I have several suggestions though, two for Eastwood & several for the person assembling the cabinet. The light is useless. It needs to be much brighter. Move into the 21st century & go with Distributed bright LEDs with a brightness control. There is a roll of 6mm sealing tape in the kit that is not used. Is it for replacing the lid seal? When installing the vacuum elbow as in figure 7A, it is difficult to get it installed. It is much easier to remove the baffle plate from the inside of the opening & push the vacuum elbow out through the seal. When assembling the cabinet the first step should be to attach the gloves to the front. It’s a real pain to attach them when you can’t see half of the attachment & there is not much room for your hands. I’m pretty mechanical but it took over 15 minutes to install the first one & about 10 minutes for the second one.

Rated 5 out of 5 by from Great but needs some upgrades: This blast cabinet is really nice, the cabinet / gun combination seem to be high quality and it's nice that you can change out the tips to the gun, (I have had previous blasters where that was a fixed thing and you had to have several guns to get different patterns). A couple of issues I noticed with using the cabinet: 1) Although it holds a good vacuum, there are a lot of spots in the joints that aren't sealed and the media leaks through all over the ground, you will need to re-seal the joints. 2) Perhaps the media I'm using isn't ideal, but I noticed that it doesn't funnel the best going back down to the pickup tube. The bottom funneling section isn't really steep enough to re-collect the media, so the media just kinda sits all over the cabinet base and then you have to shake it manually down back to the pickup tube. (Using 80 grit glass-bead) 3) You 100% need a separate vacuum system / dust collector to clear the dust while blasting. Don't get crazy, a small 1hp vacuum works great. I tried my 5hp vacuum and the suction was too great it made it difficult to maneuver the gloves around against the pull. 4) The fluorescent light is kinda lackluster, it does the job but it could be a LED that is much brighter, will probably upgrade in the near future. 5) The hoses to the gun are a little short, I added a little length to each to make the gun more maneuverable in the cabinet. I also added a quick-disconnect to the air-line inside the cabinet so the gun can bend and twist better without getting jammed up from the hose being locked at a single angle. 6) This thing is an air-hog. You 100% need a large compressor/tank combo that can keep up maintaining 80 psi while blasting, otherwise be prepared to take long breaks in between your work. Overall I rate this thing 4.5 stars / excellent. It's made very well, easy to use, lots of space, nice features such as the lift-assist shocks. Thanks Eastwood!

Rated 5 out of 5 by from Great cabinet for small to medium parts I bought this to blast dirt bike parts for a restoration project. Even with a slightly undersized compressor it works well. No it doesn't perform like an industrial size cabinet, but you get what you pay for. Quality wise it surpasses similar units.

Rated 5 out of 5 by from Terrific Product in a compact bench top size. I purchased this product for our small shop because we did not have a Media Blast Cabinet. It is a professional product with a compact footprint! Well designed with sturdy construction. I personally performed the assembly and the instructions were well written and easy to follow. Everything went together w/o any problems. An unexpected bonus was finding a second, completely assembled EOM spare lid with glass and protective tear away sheets affixed to it, included in the shipping box. A very nice surprise! A Very professional addition.

Rated 5 out of 5 by from Blast cabinet Assembled unit with no difficulty except the gloves were tricky to get installed. Everything aligned well.

Rated 5 out of 5 by from The Bottom is Tops I researched these little cabinets for awhile. Most cabinets on the market in this size have a full width v shaped bottom. Then there is a suction tube laid in the bottom. Many people complain about that setup because it often does not pickup the media. This cabinet funnels down to a single point. The pickup is screwed into this point and has a hallow bolt with suction holes in it. This design has the media collecting at a single point and that means it works. My dislike is having a screw head on the band clamps rather than a nut head. It was difficult to get the clamps tight enough on the gloves to where they would stay in place. Another dislike is that there is not a media drain. My thoughts are that there could be one. A second hole for a drain could be added near the bottom. It could be just up from the suction port hole. Then there was assembly. Everything lined up as it should. The hardware I got was complete. Some of the hardware variations were not necessary. They could pretty easily have just one size nut and bolt.

Rated 5 out of 5 by from Great Blast Cabinet for the Price I have only used commercial units at shops before. I was a little concerned about some of the reviews but when I got the unit I could see where the problems were. When assembling this cabinet, follow the directions...step by step. When they suggest silicone in certain it...and look closely to see if a little more silicone might prevent media from leaking out. I found everything fit well, overall design is good and I look forward to years of being able to blast away rust and paint from metal objects from my car restoration project. With the media added, it gets a bit heavy and hard to move. I am thinking that the extended legs might be in my future...

Is there a quality spec for the compressed air supply? "Removing all moisture and impurities" is not very specific, or technically achievable. Is ISO8573 class 6:3:2 (particle, water, oil) air sufficient?

Asked by: Tom R
We have no ISO spec recommended, but it will work with a wide range of moisture content. The more moisture you have the more clumping/clogging you may experience with the blast media. For most, simple regular draining of the air tank with a basic filter/regulator setup like our #31633 CFS will be fine.

I’ve had this unit for a couple of years and it works very well.  But I’m have a problem with the media hose collapsing both under the grate and where it comes through the grate.  I can use pliers to round it out and that works for a few minutes.  ???

Asked by: DavidF
We would recommend contacting our Sales team via email at They can put in a Parts request to have a new hose itself pulled for purchase.

What is a good compressor to buy to run this cabinet. My craftsman 4 gallon 1hp compressor cant handle it. I dont want to spend a bunch of money on a new compressor.

Asked by: Mark
To run this blast cabinet effectively, you will need a compressor that provides at least 7cfm at 90psi. When buying a compressor, I recommend getting one that supplies more cfm than the tools you currently plan to run, as this will allow you to add other air tools in the future. If you plan to blast a lot of items and ever paint, I'd recommend a compressor with at least a 60 gallon tank like this compressor - Our 30/60 Scroll compressor would also run this cabinet. Another option you do have is to plumb another compressor in-line with your current compressor to increase available air.
