The time allowed for decay depends upon the size of the system, but generally, 10 minutes minimum with 1 minute added per ton is a good guideline. The moral of the story is this: A proper evacuation may take 15 minutes, 15 hours, or 15 days, it simply takes what it takes.19 abr 2017
How long should a vacuum pump run for?
By running the pump for 20-30 minutes with the inlet blocked before connecting to your vacuum application, fewer vapors will condense in pump oil.16 nov 2020
Can I run a vacuum pump overnight?
Yes, as long as there is no safety hazard associated with continuous operation. In fact, it may be necessary to do so to pump down the base pressure.

What is the purpose of vacuuming AC system?
It is important to vacuum an air-conditioning system to remove any air or moisture that may damage the system in the long run. Moisture in the AC system is a serious problem, because moisture reduces the performance of the AC system and condensation of water can cause the AC system to freeze.
What happens if you don't vacuum your AC system?
If you do not evacuate the system to remove air and moisture, you will reduce heat transfer capability through the refrigerant because air which is 78% nitrogen is not condensable in automobile systems. Moisture in an A/C only induces corrosion and more problems.29 may 2015
How long do you run vacuum pump on AC?
With a vacuum pump connected to both, low and high air conditioning system sides pull a deep vacuum for at least 5-45 minutes. A vacuum of about 500 microns or 29.92 hg gauge pressure is needed for removing any moisture that may have entered the system along with the non-condensable gases while it was open.
Do I have to use a vacuum pump for AC?
Yes, once the lines are opened to the atmosphere they are full of air and not refrigerant- to work they need to be very nearly 100% refrigerant and refrigerant oil. Any air needs to be removed by vacuum before refilling the line thru the pressure ports.

Can you use a vacuum pump to recover refrigerant?
No. You can not use a vacuum pump to properly recover refrigerant gases because a vacuum pump does not have a compressor to reduce the gas recovered to a liquid in order to store it in the recovery bottle.
