2) Comes with metal media drain plug at the bottom instead of a cheap plastic plug which suffers from stripped threads after a few removals and reinstalls due to the abrasive media getting into the threads;
3) Greater metering valve chamber volume, especially in the area where the air enters the mixing chamber from air bleed valve, creates much greater turbulence that increases the mixing of the air and the blast media to give a steady delivery of the suspended media to the gun (see picture #5 for schematic comparison).
4) Correct style and length media hose with 2 stainless steel hose clamps
5) Virtually indestructible;
6) Costs less !!
7) Much cooler steampunk look !!
I tried the cast aluminum, conical shaped kind. Then I built this one and was very pleased with its improved performance. I think that you will too!
Thanks for looking
