Id hate to put wear and tear on my compressor when a purpose-suited unit would do a much better job and pull a better vacuum.

Though Id recommend US made stuff, few really care, so take a look there.

I would go with the Robinair 15310. Its cheaper than that cheap HF (expletive) and it ships for free.

Check the specs and the warranty.

Specs say it requires 4.2 cfm @ 90psi, your compressor puts out 6.3cfm @ 90psi, so yes, it will work. However, it puts a heck of a beating on the compressor and the electric bill, very noisy as well.
The compressor will be running non-stop to keep up for the 45-60 minutes necessary pull a proper vacuum vacuum and even then it can't match a bottom of the line electric vacuum pump.
Spend the extra $90 and get an electric pump.
I've done few jobs with an air powered pump, but never again. I rented a vacuum pump from Autozone and it was pleasure. Nice and quiet and pulled a deeper vacuum than I could ever get with the venturi pump.

I guess I'll be getting an actual vacuum pump. I thought about renting one from Auto Zone but they want $154.99. Screw that! I can buy the thing cheaper and take the girlfriend out to a nice seafood dinner. I just hope there's no leaks in the evaporator or condenser!
You can save a few bucks by getting the 1.5 cfm pump which is more than enough for DYI automotive A/C work.

Its just a deposit, plus tax, you get it back in full when the tool is returned.
However, without a CC card one would have to cough up $160+ in cash.
Also, it can be PIA to get one, its not an in-stock item. It took multiple attempts before Autozone finally had someone with a brain who knew how to order it.

I found a 3 CFM pump $108 shipped! Now to come up with the cash.
That looks like a good buy too. Definitely more than good enough for occasional use.
