1. BEST PORTABLE MACHINE: Robinair RG3 Portable Refrigerant Recovery Machine
The RG3 is an easy-to-use portable refrigerant recovery machine designed and manufactured by Robinair.
This lightweight machine features a compact design that allows one to easily carry it around.
It weighs about 18 pounds, and measures 14.8 inches in length, 11.4 inches in width, and 8.5 inches tall. Its compact design also gives it a small footprint.
It has a compact shiny casing that features a hard-to-break handle that is conveniently located on its top part. This gray outer case is not only tough to break, but it is also durable and at most times, outlives the machine itself.
One critical aspect of its solid construction is its high-efficiency cross-flow design which ensures that the layout of the condenser and fan is properly optimized to provide the shortest cycle times possible.
It is easy to operate this machine as the pressure gauges are conveniently placed on the user panel for easy reading of pressures.
Also in the user panel are the on-and-off switch and color-coded easy-to-use valve controls that regulate the inflow and outflow of substances into the machine.
The inflow valve control and its corresponding pressure gauge are colored blue, while those for the outflow are colored red.
This machine uses an oil-less compressor that features a high-pressure safety switch. This switch automatically shuts down the entire unit if the pressure inside the machine rises above 550psi (approximately 6.9 kilopascals).
RG3 can handle almost all common refrigerants including chlorofluorocarbon (CFC), hydro-fluorocarbon (HFC), and hydro-chloroflurocarbon (HCFC)-based refrigerants such as R-410A, R-12, R-22, R-500, and R-134a.
It works well with both liquid and gaseous refrigerants, but the recovery rate for gaseous refrigerants is slower than that of liquid refrigerants.
Even so, the unit rarely develops leaks and one can use it to recover gaseous refrigerants for a considerable period of time.
In fact, this is what makes it suitable for refrigerant recovery from any HVAC system from rooftop-installed to marine HVAC systems. Still, this machine is purposely designed for residential recovery.
RG3 is a single-cylinder recovery machine, but its performance is quite superb, and it can recover about 3-tonnes of R-22 refrigerant from a residential unit within 30 minutes.
This performance is comparable to some twin-cylinder recovery machines, but such machines cost much more than the RG3.
Therefore, the cost-to-performance ratio of the RG3 recovery machine is superb for its price range and operational capabilities.
It is powered by 110 volts AC power, and an IEC coupler is integrated into its design, and a power cable that can fit into this coupler is also provided. Its operating frequency is 60Hz.
Anyone who acquires the RG3 from an authorized trader also benefits from a one-year warranty from Robinair.
The RG3 is a compactly-designed, electrically-powered, and easy-to-use portable refrigerant recovery machine that is purposely built for both HVAC and residential recovery.

2. Appion G5 TWIN Twin-Cylinder Recovery Unit
The G5Twin twin-cylinder model is a compactly-designed, lightweight and ultra-fast refrigerant recovery machine designed and manufactured by Appion.
It weighs about 26 pounds, and measures 13.75 inches in length, 9.4 inches in width, and 10.3 inches tall. Its size compares well with that of the Robinair RG3 recovery machine, but it weighs more than RG3.
Even so, its heavier weight is due to its solid construction which incorporates a twin-cylinder as opposed to a single-cylinder of RG3, as well as unique components such as twin condensers.
The compact multi-colored shiny casing of G5TWIN gives it a good aesthetic appeal, and like the Robinair RG3 recovery machine, it also features a hard-to-break handle that is conveniently located on its top part.
Likewise, it is easy to operate this machine as the pressure gauges are conveniently placed on the front-located user panel for easy reading of pressures; and just like the Robinair RG3, the inflow valve control and its corresponding pressure gauge are colored blue, while those for the outflow are colored red.
The layout of the components inside G5TWIN ensures that there is an operational synergy between the operations of its twin-cylinder and the twin condensers, and this allows the machine to achieve ultra-fast recovery rates. This also makes it a high-volume refrigerant recovery device.
Another unique feature of the G5TWIN is its 7-inch 10-blade turbine fan which can reach speeds of 3000 rpm (revolutions per minute).
At this speed, the fan can blast large volumes of fast-moving cooling air over the condensers and twin-cylinder heads.
This ensures that the machine operates at a cool temperature of about 50 degrees Fahrenheit regardless of the surrounding ambient temperature.
One major difference between the G5TWIN machine and the Robinair RG3 is with regard to the range of refrigerants that each can work with.
Just like RG3, G5TWIN also works well with both liquid and gaseous refrigerants, but the gas recovery rate of G5TWIN is much higher than that of RG3.
This model features a refrigerant-isolated crankcase, which ensures that the refrigerant fluids do not come in contact with the moving parts inside the crankcase.
This prevents bearing contamination and ensures that the machine continues to operate quietly for a long period of time.
Bearing contamination not only causes the machine to be noisy during operation, but it also increases the rate of wear and tear of the moving components hence ultimately reducing the lifespan of the device.
The G5TWIN is powered by 115 volts AC power, and it draws 10 Amps of electricity. Its operating frequency is 60Hz.
It has an IEC coupler that is integrated into its design, and a power cable that can fit into this coupler is provided upon purchase of the machine. The purchaser also benefits from a one-year warranty from Appion.
The Appion G5TWIN is a compactly-designed, electrically-powered, easy-to-use, and portable twin-cylinder refrigerant recovery machine that is purposely built to recover R-410A and R-22 refrigerants.
However, when you factor in that the RG3 from Robinair is compatible with a far wider range of refrigerants, this does bring the overall value for money down on this Appion offering.

Recovery Machine Buyer’s Guide
HVAC recovery is a important job. An announcement by the US Environmental Protection Agency (EPA) phasedown of R-22, has made clear that the process is growing even more valuable.
It is an important market, which means for practitioners using the right equipment should be priority number one.
What to consider when buying a refrigerant recovery machine
If you’re currently looking to buy a new HVAC refrigerant recovery machine, here are a few things you should consider first.
Buying to meet your needs
The wide range of machines available is designed to suit different demands. Put simply, a large workshop with a whole team of employees will require more robust commercial grade recovery machines than a technician working alone.
The former needs a fast recovery time that commercial equipment can provide. The workshop setting also means heavier equipment can be used.
The one-man band is more likely to opt for a less expensive, portable HVAC recovery machine.
Weight & Portability
On the subject of portability, weight is obviously a big factor here. If you will moving from job to job, climbing onto roofs and reaching hard to get places; you will want as light a unit as possible.
Advancements in technology have seen the best recovery machines get smaller and smaller, (specific models designed for portability are very much the norm now)
When buying a machine, consider just how much portability you require, along with issues such as recovery time and cost.
For instance, the lightest units may well not compete with heavier machines designed with fast recovery times as a priority. Those few extra pounds of weight will not seem so bad if your time on the rooftop is cut in half.

We have touched on the recovery speed above. It is certainly an important consideration, especially for a large business where time is money.
The fastest refrigerant recovery machines are twin cylinder units. If speed specs are a high priority, this is what you should look for.
Be prepared to pay more, however.
Another factor that impacts recovery time is the oil-less vs Hermetic Compressors debate. The fact is, in 2017 the majority of machines now opt for the oil-less build as they offer much better recovery rates and are cleaner to run.
Larger oil-less models also have the ability to handle multiple refrigerants.

It is important to know what’s involved when it comes to servicing the recovery machine you intend to buy. If things fail, or routine maintenance is required, will you be in a position to service it yourself or locally? In some instances, your only choice could be the manufacturer.
Is there a licensed outlet nearby or will it need to be sent far afield, a situation that cost you income during the disruption?
Knowing these details in advance may alter your purchasing decision.
Environment of operation
One issue to consider if you are going to be operating your recovery machine in very hot weather is the size of the condenser. A large one will be needed in order to help keep the unit cool and to prevent it from cutting out.
Cost is clearly another issue that will affect those looking for the best refrigerant recovery machine.
Even at the lower end of the market, the prices do not come cheap. Units vary in price from $400-$8,000.
That large range is due to the demands required on a machine. As we have stated above, a busy commercial shop will need (and have the budget for) a top-level unit capable of multiple simultaneous operations as well as fast recovery times.
A small portable unit is not designed for such workload, and hence are a lot cheaper.
Balancing your needs with your budget is the key issue here.
Finally, there is the issue of warranty length. Clearly you will want as long a warranty as possible.
After-sales support is also important, especially if the unit is to be used in a busy commercial setting. Knowing that a technician will arrive to fix any problems should they occur, provides an added peace of mind.
Buying from third-party sites such as Amazon also has its benefits. Not only do online retailers often offer the lowest prices, but there is also the added protection of purchasing through a 3rd party.
Amazon is also a good place to compare prices and get the best deals.

How to use a Refrigerant Recovery Machine
The following video is one of the best resources we have found, detailing the steps involved when using a refrigerant recovery machine:
Legal Requirements From the EPA
The EPA (Environmental Protection Agency) has some strict guidelines on the certification of refrigerant recovery machines. Section 608 stipulates the following:
“Except for equipment manufactured before November 15, 1993, the recovery or recycling equipment must have been certified by an EPA-approved equipment testing organization. To ensure that they are recovering the correct level of refrigerant, technicians must use the recovery equipment according to the directions of its manufacturer.” – EPA
The regulations also cover the handling and reclamation of refrigerants, giving the EPA the ability to fine violators up to $37,500 per day, should they not abide by the guidelines.
The Montreal Protocol & U.S Clean Air Act
The Montreal Protocol was an international treaty that was signed by all members of the United Nations in 1987. It was created in an effort to help make developed nations reduce the manufacturer of ozone-depleting substances.
The U.S government amended The Clean Air Act in order to comply with the treaty. Within the Act, the EPA is given authority to regulate the use of refrigerants and, as mentioned above, can dish out some hefty fines for parties that do not comply
If you are working with a recovery machine, it is important that you are fully aware of the regulations. The handling and reclamation of refrigerants is a serious business with a lot of responsibility attached.
Refrigerant Recovery Machine FAQs
Here are some answers to common questions that come up when people are looking to buy a recovery machine for the first time.
What exactly is a Refrigerant Recovery Machine and what does it do?
Simply put, a refrigerator recovery machine is a device that is used to remove refrigerants from cooling equipment. The normal application is home and vehicle AC units.
These refrigerants have to be removed following pre-defined APA standards. There are machines for home use, (so refrigerants can be removed from your own home or car), as well as more advanced machines that technicians use for commercial work.
Can I use a Vacuum Pump to Recover Refrigerant?
Vacuum pumps are available to help recover refrigerant, however, to use one is not necessary. The most common way of removing refrigerant is by condensing it out via a recovery machine. Vacuum pumps are just an additional method that can be used too.
How Do I Restore Refrigerant Without a Recovery Machine?
These days it is possible to restore refrigerant using tanks and gauges so that you know how much is going back into the system. This process does not require the use of a recovery machine.
