Orion Motor Tech Cordless Lithium-Ion HVAC Vacuum Pump, 3 cfm Vacuum Pump, Battery-Powered Auto AC Vacuum Pump for R134a R410a R1234yf Systems, 1/4hp Single Stage Vacuum Pump Automotive

I bought this vacuum pump instead of an air compressor to vacuum fill the coolant on my 2004 prius. I didnt see any reviews or notes that it could be use in that capacity. At first I tried using my 30 amp tire inflator that barely got the needle to move on the vacuum fill kit gauge. Next I tried the Orion vacuum pump. I can say with full confidence that this Orion vacuum pump will work excellent for the vacuum fill of a car coolant system. As long as you have the correct air fittings it will make quick work of the vacuum coolant fill. Once everything is connected and you turn it on, it takes less than 30 seconds to get the vacuum needle on the vacuum fill kit gauge into the green zone. It provided a very good vacuum and I was quickly able to fill the coolant. Used very little battery, it was still reading full. The Orion being cordless is extremely convenient to take out to the vehicle your working on. Highly recommend it.

Worked awesome compact great tool

Works very well and battery holds a charge for a long time

The batery is a little bit weak, but the pump works very well.

Ha trabajado bien en 3 vehiculos que la usé. Una buena compra, la bateria es buena.

Worth every last penny, a must buy, I work as an Automotive Technician, specialized in refrigeration and love this tool

I love this little pump, on very larger AC system it takes a couple of minutes to vacuum but works really well and the battery life is really good, would recommend this to every mobile ac technician.

So far the pump is working ok, be careful not to add the entire bottle of oil that is included in the box as I did. It blew oil all over the place due to being over full (my fault). The pump isn't strong enough to pull all the moisture out of a Automotive AC system, buy a better two stage pump for that. I am using the pump in a vacuum chamber, it works okay but it is very slow to get the vacuum down to 30". It works for me I am a traveling technical trainer and the battery power is the best for the class demo's.

Muy buena y la batería excelente

I bought one of theses a couple of years ago and like it so much I bought a second one. I work as a refrigeration tech on commercial equipment and this thing will pull down a 2 door freezer in like 10 minutes. Used it last year to pull a vacuum on a York 2 stage roof top unit and it worked like a charm. The battery will pull down 1 RTU or about 7-8 self contained fridges. Weights a little more than a drill.

Me salio muy buena , lo unico es que no se donde conseguir otra bateria, ya que aveces tocan 3 instalaciones al dia

Fonctionne très bien

Excelente
