VIVOHOME R1234yf R32 R454B 3/4 HP Portable Refrigerant Recovery Machine Oil-Less, Freon Recycling Unit HVAC for Vapor Liquid Refrigerant, Car Air Conditioning

For the money this unit can't be beat. Worked perfectly for the 1 unit I needed to reclaim. Easy to use with overpressure that worked great

This machine is great. The manual is purely written but I understood what it was saying. I love this thing

I've only had to use this item once so far but it worked absolutely perfectly.

I love this machine and I am so glad I went with the one horsepower unit. I was thinking about getting a tall Robin air unit, and it does functions automatically so that you don't have to manually turn knobs and I don't like that because I don't want Electronics on an expensive machine to fail. I like manual stuff. I know it's larger machines are only that large so that they can be wheeled around and store a tank in the back.Since it does not have an oil separator inside of the unit, you should always use your filter of course when recovering refrigerant but always recover the refrigerant and gas form and not liquid so that you can effectively catch any oil mist. Remember that when you are recovering liquid, the oil is dissolved in the liquid. If you are recovering it as a gas from the low pressure side at a slower rate, ensuring that gas and only gas is coming through, you won't really have any oil lift from the system, and the filters will last much longer

Might be a nice unit if it came with the proper ancillary hoses and valves. It was advertised as "nothing additional required for use".It should also be noted that the instructions are confounding and nonsensical. The manual, and all pages within, are totally useless... Clearly the folks that knocked off someone else's product have no clue how this unit should function. Understanding the basic requirement for recovery of refrigerants seems absent from the design and is readily apparent due to the lack of necessary ancillary components.It is also important to know that anyone using this device will discharge refrigerant into the atmosphere. The purge mode instructions state to open the discharge valve after removing the recovery tank hose from the bottle and disconnecting the manifold gages prior to starting the purge cycle.....

Nice

So far a good machine. Has worked well working automotive ac

Works very well.
