You can recover r134a with a vacuum pump, but it is not recommended. R134a is a refrigerant, and when it is exposed to air, it will absorb moisture and cause corrosion.
You cannot reuse refrigerant that is recovered. The refrigerant must be recycled in order to be reused.
A recovery machine can be used as a vacuum pump if it has the right attachments. Most recovery machines have a vacuum pump attachment that can be used to suck up liquids and debris.

Everyone tends to prefer the larger or more well-known brand names even though Mastercool is just as good and, in my opinion, costs considerably less while maintaining the same level of quality. Nobody else's recovery tanks, in my opinion, could be constructed any better than these! Very sturdy tank, excellent valves, and it satisfies the specifications, which speaks much about their caliber! Consider how much freon is sold in disposable tanks that are entirely safe and constructed in accordance with federal and state requirements to contain the pressure of the gas they hold. How can a recovery that is constructed from metal that appears to be heavier in terms of weight and strength be less effective than a gas that is sold in a tank that is considerably thinner and lighter? Quality is always important when it comes to refrigeration equipment, and I have to say that this tank surpasses, if not exceeds, the standards you would expect for years of recovery at a lower cost than most! There is no way to err! No less than 5 stars!

In most cases, the tap valves that come with A/C recharge kits are worthless. Knowing that, I bought a second device with both the standard cheap tap valve and this high-quality valve. You definitely get what you paid for. This valve was a genuine delight to use after its straightforward installation on my recharge tool. You will have a valve that should last a very long time if you replace the garbage that was included with your recharge kit. Very strongly advised.

I couldn't wait to examine and use this scale. after the delivery of the package. Instantaneously, I opened it. Material for the case is of high quality. For a small scale and case, it's a little bit weighty. Overall, it looks excellent, but the lack of a battery prevented me from testing it out. You are aware that most battery-operated items come with them when you purchase them. At first, you don't need to stress about that. Just take pleasure in the merchandise rather than stressing and determining what kind of battery you require. No ill will toward that. I advise the vendor to also include a battery. It would be lovely.No one will be perplexed. Very good scale all around. Worth the investment.

The main reason I bought this item was to utilize it with a vacuum chamber I already had. The vacuum pump first of all leaks oil. It does create a vacuum, however if left idle, it spills oil. The gauges were recently used by me last night to install a mini split air conditioner, and they performed as expected when I pressure tested the system to look for leaks. I then performed an hour-long vacuum on the system and looked for vacuum leaks. This was quite successful. I then opened the system and turned it on. The low pressure side gauge stopped reading after zero at that point. The gauge is inoperable and dead. Unfortunately, we have passed the return window, so I must pay to replace the gauges. Positively, the sniffer performed effectively and discovered leaks in both the recent installation and a prior installation.(Update) This merchant went above and beyond to make things right. They did replace the full purchase, but I haven't had a chance to use the replacement.

The performance of this tiny device is excellent, especially for automotive applications. For some reason, Robinair does not make the user guide for this machine available on their website. This is ridiculous in my opinion, especially considering that I almost didn't buy it due to contradicting information concerning refrigerant compatibility that was available online. Finally, I took the risk, and sure enough, the instructions states that it is suitable for R-134a.It recovers 2 pounds or so in approximately 30 minutes.If you want to perform this type of work yourself and live in a hot area, you should buy this machine. You'll be able to save a lot of money. As soon as diagnostics are required to track down issues, the cost of AC service quickly increases. With your funds, you could easily cover the cost of this device.To get equipped to work on your car's AC with simple equipment like the RG3 here on Amazon will run you roughly $700. Learn more about it on YouTube, and you'll soon be maintaining your composure.

superb scale The handheld reader screen, which you can position in a more accessible location so that it can be read easily once something is loaded into the scale, is its best feature.The scale is simply detachable from the carrying case and can be placed back into the box.It does not turn off after a period of inactivity, which was ideal for my prolonged use when gauging the amount of butane escaping the cylinder.Anyone with a negative rating received a subpar item. Mine has been in continuous use for almost three years.

I was obtaining gauge sets on loan from a few auto parts retailers. I was only attaching up to 1/4 of the time "Schrader valves and other adapters were required with current gauge sets. This set is vintage and screws into 1/4." "with no end r134a adapters (source of some bad reviews). A reviewer who claimed otherwise likely had the hoses attached improperly or neglected to remove the pin that depresses the schrader valve. Having this around was worth $36 on its own. I believe it will endure if lovingly handled. I strongly advise looking at Enviro-safe or other r12 replacements if you are working on outdated r12 systems. I think it fits better, because r134a is being stigmatized and phased out as the patents run out. Get away from corporate/government abuse by joining the rest of the planet.

I lack knowledge and experience in diagnosing and recharging air conditioning systems. The gauges were simple to put together and operate. As several commenters have noted, the gauges are in Celsius. The kit contained an adaptor to go from the gauge set to the can tap that I purchased separately, and the gauges come with everything needed for R-134a systems except the can tap (I purchased my R-134a can tap locally, but it is similar to the taps offered on Amazon by WINOMO or the Interdynamics DV-134). When the R-134a fast coupler was removed, the gauge hose fit to the low side of an R-12 system, but I did not need or even consider getting an adapter for the high side since I was only using it to fill one can into an old truck. I purchased a Robinair 10102 side can tap for the R-12 can that worked well and had two different sized fittings, one of which was sized to accept the gauges yellow hose and simply screwed on. The other fitting on the Robinair side can tap accepts the adapter included in this kit if you wanted to do that for no apparent reason, after which you would screw the yellow hose to the adapter. The gauge hose connections for the yellow and blue hoses for the R-12 system are therefore put directly onto the can tap fitting and the low side fitting in the car. The provided adapter in the kit fits to the can tap, and the fast couplers given in the kit fit on the high and low connections at the vehicle for the R-134a system. For the two vehicles I worked on today, the gauges functioned properly, and overall, the quality seemed to be ordinary or adequate. This OrionMotorTech gauge set allows you to precisely monitor an R-134a system's condition (not for R-12 without the additional purchase of a high side adapter). These gauges are SO MUCH BETTER for filling R-134a systems than the R-134a refrigerant cans that are sold for filling systems with a one-piece cheap gauge and short hose. In my experience, those have consistently been annoyingly wrong, and I believe they are useless. Accurate information on inspecting, filling, and gauge pressure readings on the internet is difficult to find, but I discovered it here: vehicleairconservices/page/gauge readings, which was helpful for diagnosis and fill. I believe this tests the system's overall fill pressure and if it is low overall, probably requires a recharge. Start with the vehicle on and the air conditioning off and use the corresponding pressure chart. Use the A/C on chart and turn on the A/C to its maximum setting while keeping the windows open. Basic diagnosis information is also provided. At your own risk, use all of this material. I've already said that I don't know much about air conditioning systems, but I am a graduate-level backyard mechanic. I believe the price is reasonable.
In order to properly recover refrigerant, you must first identify whether the system is a high or low side system. A high side system will have the compressor located on the "high" side of the system, while a low side system will have the compressor located on the "low" side. Once you have identified the system, you can then proceed to recover the refrigerant.
If your car's air conditioner isn't working, you may need to recharge the refrigerant. You can do this yourself without a machine, but it's important to know what you're doing. Otherwise, you could damage your car. First, make sure the car is turned off and the engine is cool. Then, locate the low pressure service port, which is usually blue. You'll need to unscrew the cap and hook up the can of refrigerant. Start the car and turn on the air conditioner. The can of refrigerant will start to
If your refrigerator is not cooling properly, it may be necessary to evacuate the refrigerant. To do this, you will need a few tools and supplies. First, you will need to locate the refrigerant lines. These are typically located near the back of the refrigerator. Next, you will need to disconnect the power to the refrigerator. Once the power is disconnected, you can remove the access panel to the evaporator coils. At this point, you will need to attach the evacuation hose to the low pressure side of the system. Once the hose is attached, you can open the valve to
A recovery pump is a type of mechanical device that is used to circulate fluids in a closed loop system. The pump is designed to maintain a constant flow rate and pressure within the system, regardless of changes in temperature or viscosity of the fluid. Recovery pumps are used in a variety of industries, including automotive, aerospace, and manufacturing.
It can take a long time to recover refrigerant from a system, depending on the size and type of system. For example, a small, domestic fridge may only take a few minutes to recover the refrigerant, while a large, commercial system could take hours. The main thing to remember is to follow the manufacturer's instructions carefully and to always work in a well-ventilated area.
There's no definitive answer to how long a AC system should hold vacuum, as it can depend on a number of factors - from the quality of the vacuum pump being used, to the level of experience of the technician. However, as a general guide, most AC systems should be able to hold vacuum for around 30 minutes without any issues. If the system is losing vacuum more quickly than this, then it's likely that there's a leak somewhere that needs to be fixed.
