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.

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.

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.

Una bomba maravillosa, liviana y efectiva y bateria q dura ..muy recomendable

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

Terrible pump, quality is ehh battery dies after about 30 minutes holding a vacuum, also had it in my truck and it leaked oil absolutely everywhere and the cap came apart I’ve had a few vaccum pumps but this one sucks

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

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.

Excelente

Fonctionne très bien

Apenas llevo 3 vacíos (uno de ellos lo dejé 1 hora con 20 minutos y se acabó la pila) Conclusiones: Para equipos de 12 mil btu esta perfecto, equipos más grandes no lo sé si es lo mejor La pila dura más de lo que dice el fabricante, aunque tarda casi 24 hs en cargarse desde 0 a 100%. Es muy compacta, muy liviana y muy cómoda. Por el precio la recomiendo mucho. Solo me gustaría poder adquirir otra pila pero no sé dónde conseguirla
