I think this should get more replies in another part of the forum, rather than the " Tech Support, General Q&A, Site Feedback" here.

Possibly in the Shop Talk - BladeSmith Questions and Answers section

Thanks I will try to find that and post there. Be safe.

You need a vacuum pump. A recovery machine doesn't draw as high a vacuum. It works different than a vacuum pump.

You should be able to trade the recovery machine to an AC tech and get a vacuum pump in exchange.

Thank you for the info. In my mind I was thinking , ok it has to vacuum or suck out, so I ask my buddy to make sure it sucks. He put his finger over it and it did so I thought great , free unit better than Harbor Freight. Then I thought welllllllll maybe not. Hence me asking folks more familiar with this stuff. Thank you sir, you saved me from wrestling with that 75 lb. machine.

It is a pump. Pumps push things, vacuums suck things. The recovery pump does draw a bit of a vacuum as it pumps out the Freon into a recovery tank, but not to the same level as a vacuum pump exhausting all air from the lines before charging the system.

That makes sense. Thank you again

recovery machines are rated at 10 to 15 Hg vacuum and wont remove moisture very well. a good vacuum pump can do 29.xx Hg. basically double what the best recovery machine can do
