@love2hvac: Great question about Gas Ballast. We should close it between 1000-3000 microns. (varries by manufacture) the gas ballast allows air to enter separating the 2 stages to prevent the moisture from condensing in the existing air. this keeps the moisture out of the pump oil and keeps the pump oil lasting longer. the vacuum pump oil makes the seal inside. The moisture contamination breaks that seal and reduces how deep we can go and taking longer to pull down. quality, clean vacuum pump oil is essential. #hvac #hvacr #vacuum #love2hvac
I have never been able to get jbs to work, my fieldpiece is np, if i open on any jb ( some new ) it just removes oil

Navac filters will start rusting and you will notice rust chips inside the sump.

Is there anything you need to do for storage if a vacuum pump isn’t going to be used for months at a time? I’m in a northern area and only do AC work a few times in the summers

I have closed mine around 2,000 microns and sometimes at 1,000 microns. Depends on how fast it pulls down.

I have Jb platinum 7cfm that just blows oil out the ballast no matter how full the oil is.

I like to drain my oil upon completion of an evacuation while the case is still warm, and store it dry. Putting fresh oil in before every pull. Thoughts?
