YaeTek Pneumatic 4.2CFM Air Operated Vacuum Pump A/C Air Conditioning System Tool Auto

I really thought this product was not going to work too good for the price it turns out it worked better than expected very impressed, super affordable, and would highly recommend it

En realidad es un venturi, si funciona no se si sea tan eficiente pero lo probaremos, el precio ya no corresponde con lo que es, pero funciona

With the right Air Compressor this product puts on a nice vacuum on the closed air conditioning system. No water left behind.

Worked exactly as expected! Easy to hook up to your mainifold gauges. Just add a quick connect to the back and turn on the compressor. I used a 21gal compressor and only needed to stop the vacuum pump twice to let it recharge. Feels cheap but worked great. Only thing that I didn't like about the vacuum is how it evacs any remaining freon into the casing of the pump. Cleaned up easily. Also DON'T buy the "recommended with this item" fitting they list unless you are positive you need it. Your manifold gauges should fit the pump already and the fitting is for the evac pumps with a motor. You CAN'T return the fitting so be careful about buying it. (Since when can't we return Prime items?)
