These designs are pressurized air to force abrasives in the sandblasting tank onto material to be treated.Since these systems are “open systems” they require arrangements to collect the spent particulate for reuse.In this design line we offer 18, 30,140,230 and 580 liter sand blast pots.18,30 and 230 liters sand blasting tank are stock items and can be delivered of-the-shelf whereas the other sizes need to be ordered for manifacture.All items in this line have two wheels as part of their design to faciliate repositioning of the tank when it is empty.Operators of these equipment must wear special protective headgear fitted with pressurized breathing air connections containing carbon filters.
