BHO PURGE SETUP

Would a 1 gallon dessicator, and 3cfm single stage pump be good enough to purge around 7G of oil.

I just want to make sure it is strong enough to reach 30hg for a full vac.

And Also big enough to purge that much at once.

Here is the one I'm looking at:

Please any information on this setup or any would be helpful thanks in advance

You can pull -30hg with that but it's total overkill. If you plan on doing a 7g run all the time then it's worth the bucks but you could get away without the dessicator chamber. I use a similar vac pump but I use a modified mason jar which works fine wrapped with a heating pad. I typically do smaller runs than you though
