I had one of those. It'll pull good vacuum, but the CFM is so low it'll
take time to evacuate a moderate sized space.

I upgraded to a brand new robinair pump. A little more money, but worth it.
I use mine for vacuum processing and casting of urethanes, pulling hard
vacuum fast is a good thing. This thing pulls a 12qt bowl down to 29" + in
less than 30 seconds.

Two stage is necessary to do a lot of interesting stuff. Some of the
really interesting stuff requires a much harder vacuum than you can

This pump is close enough I can drive to pick it up. Will it
do the job??
