Most sandblast cabinets feature a blasting enclosure, and the enclosure usually contains either a combination of stationary blasting jets and a blasting table or a handheld blasting nozzle that can be accessed through a built-in, protected handling system.
Many sandblast cabinets feature durable glass or plastic paneling that allows for easy monitoring of blasting progress while preventing the unwanted spread of blasting media. Large blasting cabinets can be automated, and such systems are particularly valuable in large-scale treatment operations because of the minimum of technical supervision required to operate them.
Companies with dedicated media blasting services make frequent, and in some cases exclusive, use of sandblast cabinets in surface treatment operations. The extent of the benefits offered by enclosed blasting areas cannot be measured. In terms of cost-effectiveness, environmental-friendliness and the maintenance of safe workspaces, the introduction of blast cabinets was a major development for the media blasting industry.
Media blasting, depending on the variety of media used, can contaminate air with large volumes of blasting dust. Depending on the composition of the dust, it can pose serious health risks to people who are regularly exposed to it. The debilitating, incurable lung disease silicosis is caused by prolonged exposure to silica dust, the source of which exposure happens primarily as a result of unsafe sandblasting conditions.
Sandblast cabinets effectively capture all dust created by media blasting processes, eliminating risks to workspace air quality (though additional provisions like protective clothing, respirators and proper ventilation should still be made as precautionary measures). Media blasting is by nature a materials-intensive surface treatment process.
Large volumes of blasting media are necessary, especially in large-scale surface treatment operations, and that media has to come from somewhere. Blasting cabinets allow for the reclamation of expelled media. That media can then be cleaned and re-used, reducing the need for new media, which in turn cuts costs and mitigates the negative impact of blast media-related environmental degradation.
Especially in the case of more expensive media substances, blast cabinets that recycle blast media are a major factor in maintaining cost-effectiveness for media blasting companies.
