Negative pressure cabinet

The negative pressure cabinet is constructed as a single unit from steel sheet with only a few weld seams. Two double-walled side doors which are foamed for noise insulation enable easy loading of the cabinet. The adjustable door latches guarantee dust-free blasting even after years of use. A powerful extraction system positioned below the working grate pneumatically conveys the grit/dust mixture downward and out of the blast chamber to the reclaim system. The negative pressure in the cabinet generated by the extraction and the air intake ducts above the viewing window assure a clear view during the blasting process.
