I am a certified a.s.e. electrical/ electronics tech for gasoline engines. I am impressed with the ingenuity of this pump. Yes, this will work. The pump pulls vacuum causing the air (water particles) to boil and leave the system.
Hey, did you put in an inline oiler or do you add an ounce or two of oil for every hour of operation? You should...
Anyway, I plan on converting the AC pump on my car to be an air compressor so that I can have onboard air for my train horns (and for pneumatic tools)
@garybch I am an MVAC Tech (Mobile Vehicle AC). 500 microns is recommended. I would never use this setup on a customer vehicle, BUT, for a guy pulling a vacuum on the AC system in his own car, Hell Yeah! If the Low Side gauge gets somewhere between 29 and 30", automotive systems really couldn't care less about microns.
That setup just shouts "ingenuity". With the cooling fan for the compressor, etc. someone really put some thought into it. I love it. :)
@lsrx101 Exactly right. If you can get over 29.5 inches (gauge, not absolute) you've pulled the boiling point of water down under 60F. Hold it there for an hour to be sure, but its enough to be sure the water is gone. 500 microns would make the evacuation pretty much instant, but isn't necessary for us shade tree types.
You are not an idot. The idiot is the person who goes out and spends 300 bucks on a store brought pump. The smart person is the guy who builds one from a refridgerator that they found in the trash.
its funny how people will read this and blast you as an idiot when they are in fact the idiot. all you are doing is pulling vacuum, its not a big deal. you dont need to spend big bucks. the gauge doesnt lie. nice job brother!
I am an ase cert master. And NO SIR! Your are not an idiot. I love seeing do it yourself pumps and contraptions. I have a BUNCH of things of that nature.
hah, thats actually a really great idea, so basically he took an old ac compressor off of a car and some kind of fan motor ran a belt on em then had a fan to cool the compressor and it works only as a vacuum
This comment has received too many negative votesshow
So, how does this idot know how well it really works? Its doing a really good job compared to what? Didn't compared it to microns. Guage vaccum and microns are not the same. Microns is the standard unit of measurement.
HEY I am a ASE Certifited Master Tech. in Automotive and Medium/Heavy Duty Truck. All I know is that I hooked this contraption up and it pulled a vacuum, just like the big machine does at the shop I work in. I AM NOT AN IDIOT!!!!! I have been a professioal tech for over 24 years. I figured some people might get a kick out of this thing. Still, it was better than putting the refrigerant in without vaccing it down. It's been 2 months now and it is working fine.
@HVACJunkie Maybe you're an idiot! You can't even spell Vacuum! For HVAC, inches of vacuum is the common reading. Usually microns are used for ultra high vac applications like in electronics.Awood: good for you!
@HVACJunkie Thats like saying you don't know how tall someone is because they measure themselves in inches not in meters. If the math is too hard there are charts available...

sweet setup! FYI - I have a regular A/C vacuum pump and it says to put some ATF in it before & after each use, might be good for yours as well.

Most American cars will work just fine even without any purge. The dryer will take care of it!
