I would say no. Both pumps do the same thing so very low vacuum of 1 torr or better would not be attained. Even lab' rated vac' pumps only pull down to 5 torr.

You need very specialized ( read : Expensive.) equipment to pull a near pure vacuum.

I would say that is is impossible to pull a pure vacuum.

I can have access to a vacuum pump used in a lab, problem is getting permission to wheel my car in there. And then explaining of why I need that sort of vacuum in my car A/C

btw - funola

I have lived in third world countries where resources were scarce, I regularly saw A/C work being done by pressure testing with a junked refrigerator compressor pushing air in the system.

It was good enough - cant say about longevity, usually A/Cs were taxed to the max as summer meant 120F in the shade.
