I have used a venturi as well for vacuum bagging. (I use a system meant for
laminating: https://www.qualityvak.com/air.html.)
I'm sure a true vacuum pump would get a harder vacuum, but for most
purposes a venturi works well enough.
Now, if you don't have a good air compressor, then a venturi is less
appealing.

Guys in the know
I am going to be purchasing a vacuum pump in the near future and there
seems to be quite a few options.
I plan to use it for the following:
- degassing propellant for research motors
- vacuum bagging of composite laminates for fins and tubes
- testing of electronics in a chamber.
I am not necessarily looking for the best price. I am looking for a pump
that will meet my needs and not be something I need to worry about not
performing as expected.
Does anyone have any recommendations?
Thanks
Lee
