A refrigerant recovery machine pulls refrigerant out of an air conditioning or refrigeration system into a tank. The machines on Amazon.com range from compact single cylinder units to dual cylinder models, and from general HVAC tools to ones aimed at automotive refrigerants. Refrigerant handling is regulated in many places, so a buyer should read the maker’s documentation and local rules; this article only compares listing details.
We compared six machines using each product page on Amazon.com: motor size, cylinder count, weight, listed refrigerant types and extras. We have not used these machines ourselves, so claims about speed or durability are the makers’ own. Where a page contradicts itself, we say so rather than guess.

The 6 Best Refrigerant Recovery Machines
1. PBAUTOS 3/4 HP Recovery Machine
A 3/4 HP single cylinder oil-less machine on 110 volts that handles vapor and liquid refrigerant, with blue and red gauges, a purge switch, a replaceable filter drier and an overload protector. The page lists a 70 dB noise level, 29.8 pounds and 18.11 by 12.2 by 16.54 inches. The title carries no brand, though the overview names PBAUTOS. The data disagrees in places: the overview shows a maximum pressure of 26 bar and a 100 liter tank, while the bullets mention shutting down above 558 psi, which is about 38 bar, so confirm specifics with the seller.
Suits: a basic single cylinder unit with gauges. Strengths: self-purge and a replaceable filter drier. Weaknesses: inconsistent pressure and tank figures and no named refrigerant list. Skip it if you need clear documentation.

2. Appion G5Twin Recovery Unit
A compact twin cylinder unit that weighs 24 pounds and measures 11 by 15 by 12 inches. Appion describes twin cylinders and twin condensers, a refrigerant-isolated crankcase, a 7 inch fan and recovery of R410A liquid and vapor. The page also carries odd fields such as frost free and freezer capacity of 3 liters, which look like carry-overs from another category, so treat those as listing noise.
Suits: R410A work with a light unit. Strengths: twin cylinders at 24 pounds. Weaknesses: the page names only R410A and has misfiled fields. Skip it if you need a broad refrigerant list.

3. Hilmor 1950536 Brushless Recovery Machine
A brushless DC machine with a digital LCD, built-in hoist points for carrying and a power cord wrap. It weighs 25 pounds. The sizes disagree: the title reads 9.6 by 5.4 by 13.3 inches and the details table reads 12.7 by 15.6 by 14.7 inches, so check which figure applies. The page does not list refrigerant types.
Suits: a lighter brushless unit. Strengths: LCD screen and cord wrap. Weaknesses: conflicting dimensions and no refrigerant list. Skip it if you need a confirmed refrigerant list.

It ships with a shoulder strap, a filter drier and a detachable power cord, weighs 29.8 pounds and measures 16.7 by 9.2 by 14.2 inches. The maker lists a three-year replacement warranty and email and phone support in the US.
Suits: dual piston work with support. Strengths: a 3-year replacement warranty and a strap. Weaknesses: refrigerants are not listed on the page. Skip it if you want a refrigerant list on the page.

5. Robinair 25700 Recovery Machine
A machine for contaminated R-134a and R-1234yf recovery from vehicles, with an oil-less compressor for liquid and vapor, 2.5 inch gauges, an inlet filter screen, a 1/2 HP motor on 103 to 127 volts and 60 Hz, and low-side hoses for both refrigerants. Robinair also lists a high pressure shut-off at 435 PSI and a tank shut-off at 80 percent. It weighs 32 pounds and measures 22.5 by 10.35 by 14.5 inches.
Suits: automotive R-134a and R-1234yf work. Strengths: a named brand with hoses for both refrigerants. Weaknesses: the heaviest in this group and aimed at vehicles. Skip it if you need a home HVAC refrigerant such as R410A.

6. Jack Boss RR250 Recovery Machine
A 3/4 HP single cylinder machine that the maker says moves vapor and liquid at up to 4.85 pounds per minute. The listed refrigerants are R32, R1234yf, R134a, R12, R401A and R410A, and the maker states it is not for flammable, explosive or corrosive refrigerants. It adds a filter screen with a built-in dryer, a high-pressure cut-off at 38.5 bar (558 psi), a self-cleaning purge mode and a gauge. It weighs 29.7 pounds.
Suits: a broad refrigerant list in one unit. Strengths: a named list of six refrigerants and a dryer. Weaknesses: the page gives little brand background. Skip it if brand background matters to you.

- Included parts such as filter drier, hoses and strap.
For use, follow the maker’s instructions and your local rules on refrigerant handling.
Mistakes to Avoid
- Assuming one machine handles every refrigerant.
- Trusting a spec that the same page contradicts.

- Ordering a vehicle-focused unit for home HVAC work.
Refrigerant Recovery Machine FAQ
Does cylinder count matter?
Makers list dual cylinder models as faster, but speed claims are the makers’ own and vary by refrigerant.
Why do some listings show no brand in the title?
Some sellers list under the product description only. The brand appears in the overview table, as with PBAUTOS here.
The Short Version
For a basic single cylinder unit, the PBAUTOS. For a light twin cylinder R410A unit, the Appion. For brushless carrying features, the Hilmor. For dual piston with support, the Inficon. For automotive refrigerants, the Robinair. For a long refrigerant list, the Jack Boss.
