Do all Robinair pumps (the current 15xxx series) pull a solid 29.9"-30"/hg regardless of their cfm ratings?
It’s just because even on the Robinair site it doesn’t state any of thie max vacuums that they can pull (I only saw one spec on an ebay sale of 50microns (29.9"hg) but I don’t know if that applys to the other models also)
thanks
