Any Experts in BHO vacs? (question about vacuum size)

I've got a oilless diaphram pump it's a 2 head, 2 cfm, 200mbar (approx 80% absolute vacuum I)

Will this allow me to successfully purge BHO.

My other option was a pump that went to 50mbar which is approx 97% absolute vacuum.


For bho what's better a 200mbar pump or a 50mbar pump?

Do I need close to absolute vacuum or will that suck all the good shit out with the bad when I purge.

Is a 97% absolute vacuum a good or a bad thing for our application?



Is this chart telling me I wont be able to purge bho since 200mbar only goes to 23.94 inGH?

Short answer. No. That will not properly purge BHO

Ok thanks. Is it possible to run a higher temperature inside the vacuum chamber and a lower inHG?

That link should answer any and all questions.

Ahhhhh I fucked up. Been researching vacs for a week but In between mbar, cfm, torr, Pascal, , microns etc.....the only one i had to follow was -29inHG (.5mbar)
Gotta return that one I guess and just gonna grab a rotary vane one that will do it and call it a day. Thanks bro

I'm actually glad I fucked all that up. Ended saving myself a whack of paper....... that diaphram pump cost 500 delivered......but off amazon I can get a pump, vacuum chamber, 2 electric skillets, 1 electric griddle, a 20" glass extraction tube, for 420 bucks........
