Vacuum chamber inlet port
Vacuum chamber inlet port
(OP)
We are having a large (2.5m dia X 20m long appx 100m^3)vacuum vessel being manufactured. I have never dealt with a vessel this size before and would like some thoughts on the design of the inlet to let it back up to atmospheric pressure. In particular I am concerned about the possible noise generated and the time taken.





RE: Vacuum chamber inlet port
The greatest concern is picking up contamination when you release the vacuum.
Your venting requirements are a function of the time available and what gases are used to back fill the chamber
