10.4 Ventilation and dedusting
It is very important to catch efficiently the dust generated during the abrasive blasting process and to separate it at an efficient filter plant. Vibration facilities or pneumatic dedusting processes are applied to clean the filters. All air pipes are built in a stable manner, and they are protected by labyrinths or baffle plates. In winter, it is possible to feed the cleaned air again into the blasting hall to save heating costs.
