Hi Jim, I like the separate container for the beads for two reasons. #1, it is easier to empty or change the beads when they become too dirty or broken up. #2, if the unit gets plugged up it is easier to locate the clog. Also, I usually keep 100 pounds of beads in the hopper/steel wastebasket and the pipe out of the box sticks down into the container so it fills it as it uses the beads and there is nothing to seal. It has worked wonderfully for 16 years.

Siphon feed Blasting cabinets I've seen and used have all had the hopper emptying into some sort of separate vessel for the recycle. Is the separate vessel necessary? Why not just keep enough beads in the bottom of a closed bottom hopper, and recycle beads right from the bottom of the hopper. Seems like this would skip the extra vessel and sealing complications?
