I started with one like that years ago, and got frustrated with it because it just would not pull enough of a deep vacuum to do a good job. Especially when the system has been apart and full of air, not just an evac and re-fill.
I bit down real hard, saved my lunch money, and bought the little Robinair two stage 1/8 hp pump. It has paid for itself many times over.
Running the air powered pump, you also have to make sure your air compressor can deliver 4+ cfm at 90psi for over an hour.
