The only bad thing that I have noticed about the Central Pneumatic sandblaster brand is its inability to keep a consistent flow almost like the characteristics of a siphon system. This is probably due to having an imperfect design and the abrasive media being exposed to moisture from the supplied air causing the abrasive to clump up. I usually have to tilt the pot sideways slightly to make sure all the abrasive gets funneled down while sandblasting. I recommend trying to configure a better air/moisture filter to extract any moisture from mixing with the abrasive in the tank.
All together, the Central Pneumatic sandblaster is a great inexpensive alternate for a hobbyist to use or for people to get a taste of what the pressure pot’s advances can do without the high cost. It will get the job done, while providing a high blasting power for multi-staging, but with some inconsistent flow characteristics.
