YaeTek 4CFM 1/3HP Rotary Vane Air Vacuum Pump HVAC A/C Refrigeration Kit AC Manifold Gauge Set w/Leak Detector R410a R134a R12 R22 R404

Great unit , works great does the job

I bought those air conditioners that required the compressor unit to have the moisture sucked out of it and found a video of doing it.It required a vacuum system like this to make it work and it did it perfectly

Very nice set, comes with everything you need for a good price. The only concern I have is in all the videos I watched of people vacuuming out the A/C lines the vacuum got to -30 on the gauge, this vacuum could only achieve -15. I ran it for an hour, then let it sit for an hour, no leaks so I charged the system up and it’s working great. So it seems to have done the job, I just presume you would get more suction from a higher priced vacuum pump.

I purchased this kit as a recommendation by a YouTuber for installing a mini-split. Worked well though the pump did take time to bring the vacuum down. A stronger pump would be better if you are doing this for a living.

So I purchased to vacuum and service my Excursion. When I added 4 cans of R-134 something was not adding up. First of refer to my photo of instructions and just make sense out of that 1st. Next as I was troubleshooting the problem refer to the 2nd photo to see they have labeled the gauges backwards. I guess a 50/50 shot for them. Seeing one will be right. With needing to do the process over. I contacted their customer service, well what they wrote made absolutely no sense. You really need to stay clear of this kit. All the ones out there are made from the same Chinese factory with different Chinese companies putting their name on it and sometimes painting the pump a different color. You are dealing directly with China and be prepared to have to figure out what they are saying or referring to.

I work at home doing side jobs. Needed a pump that was handy and did not want to go to a shop and get charge way to much for a a/ c service. This pump worked great light weight and came with a bag to carry. Highly recommend this product

The pump is good enough for light use. It will pull enough vacuum to service a/c systems. I managed 29". At low altitudes I'm sure it would get close to 30. If you're just buying the kit for the pump it's a good deal. The hose fittings are terrible, it seems the threads were all cut way too sloppily. I had a very hard time getting them to seal. when I tried to measure positive pressure while charging my heat pump, the hose blew off at around 50psig
