¿ªÔÆÌåÓýHello Actually this is in work¡. Hmmm did not really think it was that lager (8.25 CuFt.) A turbo would be awesome but the cost is ¡ well ???? So for now a Diffusion will have to do. Looking at a 6¡±, but will be adequate for reasonable pump downs( 1-2 hours)? Will check out your link and review Thanks Bill ? From:

Andrew N. (KSC-ASRC-491)[ASRC AEROSPACE] ? ? I would be more concerned about getting the chamber before thinking about the pumps.? A 36¡± diameter chamber is not a trivial thing.? Do you already have one ??? ??I searched ebay for a year before I found something that big to use and then it was a year more to re-condition it.? ?? ? I suggest a turbo pump for the high end and a really big bad mechanical for the atmospheric ?to low evacuating.? I run a Leybold ??similar to this ? but 3 phase.? My chamber is bigger than you are thinking about but your chamber will take a pump this big or many many hours of a smaller one.? ? Drew in sunny Florida ? From:
