@@JoselitoR690 before when I was younger, I did not care if it was light or heavy. But now after more than 40 years of constantly picking up vacuum pumps . I don’t like heavy anymore and it seems like more things feel like they’re heavy . Everything is gaining weight. 🤭👴🏻
What setup you would recommend for small 12-14oz systems in where I need to go down to 70 and less micros? I am thinking about getting 8cfm VP87. Currently having difficulties with my pump that is after 2hrs getting hot and starts getting weaker the longer it stays running. I am typically reaching 100-120 in an hour than it just weakens more and more so in 6hrs it only capable to go down to 450-500 microns. Oil change only helps to do one job than I have to change oil again otherwise cant reach the 70 microns target
@@aleksgrigorev2717 VP 87 would be more more than adequate. If you did need to change the oil. if you watch their oil quick change videos, you’ll see how extremely easy and fast and a very small quantity of oil that needs to be changed. That’s if you have a lot of moisture contamination and your oil is turning all milky and cloudy.. Getting down to 70 µm if you’re talking about a car is usually difficult and takes a long time . Usually takes 12 hours to 24 hours. On a wet moisture saturated system.. And it helps if you do two or three nitrogen purge sweeps. 🧹. This will aid and removing and sweeping out the moisture molecules that come to the surface and the system, but have no more mass flow to help eject them .
How do you determine how long to pull a vacuum on a system? Are you trying to remove moisture from the desiccant if you leave the vacuum pump on for several hours? I have come across different opinions, I am just curious what yours is.
@@davidellingwood4075 we are allotted 1.4 hours total between setting up your equipment and all inspections and procedures, including vacuum to finish the job The ideas to reduce the moisture content as low as possible in the quickest time possible .

So under not normal shop operating conditions for a business you call it quits after an hour and charge it up . If a customer wants to pay the difference to have their desiccant material replaced, that is an option . but your micron gauge tells you your moisture level
Thank you Thomas for the info
I purchased one today and it’s light and powerful thank you sir for sharing your knowledge
