in 12 minutes you answered all my questions. Short and to the point. Some guys have posted videos of making a vacuum pump for 30 min to one hour and it is just a waste of time watching their videos.

this was my first vacuum pump. when I started in the HVAC trade in 1979 I worked for a one man shop "Smitty's airconditioning". after about 3 months he helped me [ he did all the soldering] build one of these from a old fridge compressor. I have no idea how well it actually worked but after seeing your video I think Ill build one and see. and a dial -a-charge haven't one of those in years. cool video thanks. great job.

Same thing here I'm just a first timer and have no money to buy any vacuum pump but someday I'm planning on using a air conditioner compressor

all done on carpet - nice work

You sir just saved me 200 dollars. Thank you

From my knowledge compressor oil reacts with the air, I'd recommend draining the oil from the unit and replacing it with air-compressor oil ;)

Schrader valves... the little valves that you removed to save the rubber seals are Schrader valves. (made in the USA) Good video, I have used a compressor I converted into a vacuum pump out of a freezer, for more years than I like to admit, for vac'n down AC units . Works just about as good as what Snap-on charges way too much for. (adjust the flame on your torch and watch pointing it at the compressor too, friends.) Oh and the larger the freezer or fridge you find usually has a larger compressor and it works a bit better. Sad that almost a half a million views only gets ya a thousand shared opinions. But I noticed most of the comments were just negative so maybe it's a blessing... Oh and also, if you work, walk, and lay on concrete enough, you will find some used carpet to put in your work shop or garage and always keep an eye out for some more to replace the burnt, torn, wet, oily carpet you abuse . Peace

I'm actually curious if it's possible to pull a deep vacuum with a compressor... I'm under the impression it can't really do that. It seems compressor is better for recovering refrigerant.

It will hold a vacuum if you shut the valve on the gauge. Also, you need to hook up the ground wire in case of a short it will trip the breaker instead of getting a shock.

​@@n0username0n I'd pay to see someone use a soldering iron to solder copper tubing with hard silver. Silver solder melts @1425 degrees Fahrenheit , your solder iron melts soft lead free solder @ 275 degrees Fahrenheit.

Solder on a open flame will turn to mush really quick if left there too long. You only needed to heat the parts up first then apply the solder with large solder joints. A open flame produces soot, which you don't want mixed with solder. Of course a high wattage solder gun would have worked also if you had one, but it's a bit tricky to use on large parts with little to no experience. Good soldering takes practice... sorta like welding need that experience to get good at it.

Great video. Thanks

To sand the stubs of tubing, turn the unit on its side, more than 90-degree turn, so the grit will not go down the tubing into the compressor. Or plug the tubing with rolled up bit of paper towel, to be removed after sanding. Just be careful not to dislodge the temporary plugs while sanding! _For better vacuum, especially for deep vacuum, pump _*_into_*_ vacuum!_ For instance: Run 2 old compressors in series, with the outlet of one into the inlet of the other. If one has larger capacity than the other, you would generally want to put it on the low-pressure side, for maximum pumping rate, but valving varies and some valves require more pressure to open than others. The one with least valve restriction at low pressure should be the one connected to the system being pumped down. Also, a proper vacuum pump can be boosted with a crap pump like a single old compressor, IF the proper pump has a vacuum fitting on the outlet. Another way to go is to pre-evacuate a large cylinder and attach it to your pump outlet after it has pumped what it can out to atmosphere. You also can increase pumping speed --and protect your pump from water damage-- by using a makeshift cryopump; that is, pumping through a U-shaped section of larger tubing you have prepared for the purpose of dunking in ice water with salt poured over the ice. Salt over ice makes the briny solution temperature drop to near zero Fahrenheit, so it can condense some water vapor even in vacuum. Better still, submerge the makeshift cryopump in a container of dry ice and alcohol, or if you can get it, use LN2 (liquid nitrogen). Copper wool (or brass wool or stainless-steel wool) inside your makeshift cryopump will improve the performance by adding a large surface area on which the pumped molecules can slow, contract, and even solidify. Purging the whole system with *very dry CO2* will allow you to turn a crude vacuum into a high vacuum if the cryopump is chilled with LN2, because the CO2 will solidify on contact with such low-temperature surfaces. Other gas molecules being carried along by the CO2 will get buried and trapped in the dry ice formed in the LN2-cooled cryopump. Normal refrigerants will also solidify in a LN2-cooled cryopump. With proper valves installed and operated, you can make a laboratory-grade vacuum in a cheap way. After using the cryopump, be sure to warm it up and pump it out with your regular pump, to dry it thoroughly. As always, higher temperatures of the system being pumped will speed the process of evacuation. Water is particularly sensitive to temperature and will basically not pump at all near 32 F (0 C) unless the vacuum is prolonged and very deep.

How many microns did it pull down to?

Refrigeration compressors are low volume, for faster vacuum use an AC compressor for an old windows AC. drain the oil into a container before soldering, then add it back In. I'd put a suction line filter neutralizer on the suction side to protect the compressor.

I love the comments at the end because you can tell they live in the country. The only way it's going to get tipped over is if somebody leaves in the way of foot traffic, probably after drinking too much Budweiser. Keep the junk out, like dirt or dust, so you guys don't vacuum your houses on a regular basis. Got it.

Beware!!!! While working in the "80's" in western oklahoma some of fellow tradesmen were using old refrigerator compressor to evacuate some refrigeration systems on grocery stores. I had just been out there and I myself had used one of these compressors to evacuate a system. When I got back to Tulsa a few days latter my service manager come to me and says " do you still use a frigidare copressor to evacuate systems (sp) on your truck" I said Yes. He said take off and don't use it anymore. He said one of the servicemen called the office to say that he had one on a system and was evacuating it . He went back into the grocery store and several minutes (maybe a hour) he heard and explosion. when got to the machine room the compressor , made of 3/8 steel had blew its top off and exited the top of the machine room. what the decided happened was the discharge line may (or may not) had gotten bump or kinked and the pressure got high enough to set the oil off in and explosive bang. Just like in a diesel engine that diesel oil and a spark (doesn't need a spark if pressure is high enough) Just giving you a warning I have never used one since.

I love running a torch on a carpet.

Can it get it down below 500 microns though? Preferably 350?

great recycle of the ubiquitous CL "free working rusty fridge" for something slightly more productive than beer chilling!! why use hard solder though? even a perfect vacuum is only a bit under 16 psi, and the pressure influence would tend to make your swaged fit tighter. plain old 50/50 you can get away with a cheapo propane torch rather than needing a more sophisticated air/gas rig. the refrigerator needs hard solder because it's a couple hundred psi differential, and it's trying to make stuff fly away from the "source" (your comp head). i know for you it's an a/c refrigeration tool, but it's a handy puppy for lots of other stuff too (like laying fiberglass, de-airing thick gooey mixtures, or collapsing 55 gallon drums, lol). also that inch and a half of 15% silver costs about 10 times what the same length of 50/50 does. good vid though, nice and to the point, not a lot of wasted time watching you do uninteresting stuff, lol. what oil do you run in it? 24 3/4 inches is pretty damned respectable, btw! think a "flap valve" on the outlet could buy you another inch or 2? hell, a ping pong ball behind a cross pin that gives a little "wiggle room" would probably work (and a ball valve for your "sealing cut-off", lol. no cap and plier juggling then). i know, "make your own damned vid, know it all!!!"... lol. sorry about that, just "fresh eye product and process improvements" ideas.

Shrader valve.

It is not a magic. The vacuum pump is essentially a compressor with some gadgets added. It depends on refrigerant, but you can end with very hydroscopic oil, and most refrigeration oils are. Refrigeration oil turn acidic when get moisture, and acid will kill copper winding. I would definitely change your oil to a vacuum pump oil. Also I would add drain on the bottom to replace oil in the future. You can build a very good fluid extractor using free fridge compressor as a source of very strong vacuum. I would use refrigeration filter/dryer to protect compressor/oil from moisture.

Hello does using a large heat sink or fan prevent compressor overheating ?

I have used these on two previous occasions and they work quite well. The biggest problem I have found is the motor can overheat and has a thermal trip inside the windings. This can be annoying when you most need it working. Ordinarily the refrigerant keeps the windings cool but of course this is no longer the case, So far, mine have lasted only a couple of months and then became too unreliable. I did replace the oil too to help cooling and lubrication.

When sweating copper tubing, always apply your solder on the side of the tube opposite from your heat. When the solder draws all the way around to the heated side, you will know, you have a solid seal. If you apply solder on the same side as the heat, you will have to work the solder around the tube as you move your heat and will never know if the solder has sealed all points. This is not as critical with small tubing but becomes more critical as the size of the tube you are attempting to sweat increases.

You said you cleaned the outside of the pipes with emery/sand paper but what about the internal side of pipe? I mean, what you did would be perfect if the extra pipe section had a larger diameter than that of the pipe attached to the pump. Did you ream the inside of pipe? There are special tools for this. Of course you have to be careful of filings getting inside the compressor but you could minimise that risk by taking a couple of precautions such as changing angle so pipe is more horizontal; setting up a vacuum cleaner nozzle very close to the point where you are working. (Yes I know there is oil inside the compressor. That's why you have to be so careful)

As mentioned in another answer there are two low pressure ports. One connection is to the circuit (evaporator outlet) and the other is the factory fill port that is usually pinched and soldered. In all the cases I have seen they both simply connect to the internal space with maybe a baffle or a simple U-bend in the pipe. So both low pressure ports work the same. Often but not always they are slightly larger diameter than the high pressure line. If you are not sure just power the unit up and check which two pipes suck and which one blows.

No you never swap solder. Electronics solder is for electronics and plumbing is for plumbing. In this case silver.

What size are the valves?

+jeff pepin its plenty enough but better to have a small empty gas bottle and an electro-valve so you will have qa nice peek suction, it is not the vacuum level but the volume of gas displacement that is important for powerful desoldering unit
