What is the best way to vac?
I currently bring my vac down in approximately 5 hg increments until oil is nice and flat at full vac. I was taught to that keeping the vac running the whole time was the best way to go for maximum extraction of residual solvents. To increase the purge I was taught to release vac and flip oil 2-4 times,
I read and see where many people don't run their vac the whole time and I can't help but wonder which method is the best for quality and safety. I have a pretty powerful refrigeration vac pump that pulls something like 15cfm and I'm not sure how many hg as it pegs out needle past -30 hg.
