Less than 500 µm and 39 seconds (*with vacuum running gauge mounted micron meter*)

- #1: A gauge, mounted micron meter is not the same as a system mounted micron meter you must know and understand a difference
#2: The micron number reached while the vacuum is running and connected to the system pulling a vacuum is not the important micron number.
It’s the micron reading after you have closed off the vacuum and allow the system to rest. Five minutes. 10 minutes 15 minutes when your vacuum has hit plateau and leveled out.
That is your system, vacuum reading. 
How does changing the oil in the vacuum pump help to pull down the microns better and remove more moisture "better"?
Thank you!!!
@@freddyhollingsworth5945 the moisture that you have absorbed that contaminated your vacuum pump oil that you have pulled out of the car that was contaminated with moisture.
It breaks the barrier seal between the rotor vein and the cylinder wall as it flashes off and vaporizes .
Kinda like your engine, getting old and breaking down in viscosity think of it that way .
You lose compression you lose power .
How do you store your refrigerant oils like Pag-46 etc? I see the oils in plastic bottles and the guys don't even put the caps on tight.... do they make a metal container for oils to be stored in and if so do they make one that you can apply a vacuum to the container, or should you use what you need out of the 8 oz bottle of oil and then throw it away?
Thanks
@@freddyhollingsworth5945 if you have large refrigerator oil containers don’t open them.
You drive a sharpened quarter inch fitting they come on copper rods and you can push them right through metal or plastic .
You can now fill them with nitrogen to push out the refrigerant oil while never introducing outside air .
And you can pour the 8 ounce bottles into metal injection syringes .
For plastic syringes .
There’s no air inside of them completely sealed as you push out refrigerant oil. It’s like a hyper dermic needle syringe no errors ever introduced.
Is there any reason other than cost not to use pure argon if I already have it for a tig welder?
Argon’s perfect it’s even better than nitrogen
It’s only the cost .
Do you find a big advantage in pulling a vacuum through the big blue hose, through your gauges, even though you're attached to hi/lo sides with 1/4 in hoses?
Since you use a overkill vaccuum pump, on a relatively small AC system compared to residential/commercial AC system?
@@MACEVES yes it still makes a really big difference in timewise even though you’re pulling through because the SM 480 V refrigerant manifold has a very large in inside diameter manifold that is also half diameter leading to the end of two 1/4” hoses
If you go over to the Facebook group
Automotive HVAC technicians
You’ll see other peoples comments what they have noticed from changing up to the big blue hose just for a vacuum hose to their gauges
@@coldfinger459sub0 yes sir, I'm already a member and been buying tools and following the procedures you have shown.
