034 Choosing the right machine for you
How to choose the wetblast machine that is right for you.
Choosing the right machine
Finding a wetblast machine to suit your needs is not as difficult as you might think
Wet Abrasive Process
Our wetblast units operate using a similar principle. A thorough mix of water and blast media is recirculated through the process gun where it is atomised using compressed air. The result is a unique combination of properties that allow a wide variety of finishes on a wide variety of surfaces.
Internal cabinet size
Probably the first question is whether the parts you want to blast will actually fit in the cabinet including enough space to maneuver your process gun

Water supply
The Dana-Ridge wetblast units recirculate water and abrasive around and around. There is however, some water used to lubricate the wiper blade on the viewing window and also when using the rinse gun to rinse off any remaining media after blasting. The standard machines tend to use a similar amount of water of roughly 24L per hour. This can be taken to near zero consumption through the use of the optional closed-loop system.

Larger machines have an anti-cavitation feature. It means that on initial start-up the pump will draw from the top of the sump before drawing from the bottom. This has several advantages. If the machine is overloaded by the operator with media, it will ensure the pump will not operate dry which could lead to pump failure. It also allows the pump to get the media flowing more efficiently on start-up. It is more forgiving in a workshop where the “attention to detail” is lacking or the new apprentice is let loose for the day.
