When it comes to a good blast cabinet, start with the construction. All steel welded is important because you won’t have to bolt the chamber to the legs. Further, you’ll have more time to blast if you get one assembled. Next, make sure it is properly sealed. Sealed at the seams and any openings. The better construction, the less mess you have during and after sandblasting.
Other popular features of sandblast cabinets include the blast system, the number and types of openings, lighting, and dust collection. Because blasting is a pretty dirty job, you want the kind of equipment that works efficiently and creates the least mess.
Making the units in the USA is important for many people. Many cheap cabinets available look attractive, but be cautious. Cheap (really cheap) cabinets will require assembly. In some cases, you have to actually look at the manual on the website to notice the “requires assembly” notice. You will be disappointed when you get a cheap cabinet and have to bolt together hundreds of bolts.
