Sand-blasting cabinet
USF Surface Preparation Group
Cabinets can first be separated into suction and pressure systems:
-Suction systems utilize the venturi principle to deliver the abrasive to the blast gun via suction (hence the name) where it is combined with your compressed air source and propelled against the work piece.
- Pressure systems use a pressurized vessel to contain the abrasive. In these systems the abrasive is metered into the compressed air stream at the pot, and travels the length of the blast hose and out of the nozzle under pressure.
