🌀 VIVOHOME 110V 1/2 HP Dual Stage Rotary Vane HVAC Air Vacuum Pump - Reliable 5 CFM Performance with Oil Bottle - ETL Listed Review

For creating vacuum on Subaru Baja and Chevy Suburban vehicles with dual air conditioning. Worked perfectly. Both systems were drained and the pump ran for hours. Had to make several descents as leaks were found and fixed. The unit comes with a bottle of pump oil which appears to be of high quality and works well. Found it was easier to give an oil bottle tip when pouring oil through the exhaust pipe. Would recommend and buy again if needed.

To be honest I was a bit hesitant to order this vacuum pump because of some negative reviews about it. I looked at a single tier but for a few bucks decided to give this one a try. And I'm glad I did. It will make home and automatic air conditioning. I used this to lower the vacuum on my newly revamped AC job on my tracker. And they took it down in 5 minutes. Leave for 1 hour to see if there are any leaks in the system, you're done. I then run the pump for 2 hours before refilling the system…

I bought this to vacuum my car's air conditioning while upgrading my R12 system at home. Worked very well for the price. I did a lot of comparison shopping before deciding to order this one. This was the best price I could find on Amazon for a two stage pump. I'm sure a single stage pump would probably do the trick, but for a few bucks I took a chance on this guy. I was a little apprehensive when it arrived as the packaging looked like a cheap import from China. (I think) After taking it out of

Suction to 9 microns in about 30 seconds according to my new CPS VG200 gauge attached directly to the connector (no tubing). With the bottom gauge kit it will only prime down to 45 microns and it will take a few minutes (most likely leaking hoses) but the mini-split installation instructions say the plumbing set needs to be under 350 microns for this pump to do it with ease can .work. Now the bad news: the first one I got was DOA (Locked Rotor). Luckily it was easy to return and a new one…

Bought this pump based on reviews and price. When I received it I tested it with my in-port vacuum gauge and it got to 14 microns pretty quickly. So I used it for the first time and it stretched to 180 microns in about 10 minutes. I thought great, let's do the next one. I set it up and start creating a vacuum, this time the pressure decreases a little more slowly, it reaches about 400 microns, and the pressure starts to increase. I close the valves and the pressure stops rising so there is no…

I'm just a fool and a curmudgeon. I try to fix everything myself. I would even do my wife's hair to save the money she spends on it, but I think she draws the line. This little pump did it. Actually twice! Because I made a mistake the first time and opened the high pressure valve when I started charging refrigerant. (I told you I was a dummy!) But this pump reduced the pressure as much as the gauge would allow. I followed the instructions of two of my heroes - Scotty Kilmer and Chris Fix on…
