Vacuum Chamber Setup with Nitrogen Backfill

[saxxie]

Hello:

I have (4) 41quart All American pressure canners that I want to turn into vacuum vessels as well as a Vacuubrand MD12 oilless diaphragm type pump. These containers will hold bagged powdered metals which are susceptible to oxidation. When backfilling I will be using bottled nitrogen gas. What valves and connections would you recommend for this application? Is there a diagram available that would depict the setup?


Thank You in advance
