I rented a 2 stage Robinaire 15400 from Runyon's. Before I left I asked them to make sure the oil was fresh. I didn't look closely (I should have) and took it home to use it and found the oil was milky looking. I tried to pull a vacuum and the best I got was 2000 microns. After wasting my time for a bit I took it back and asked for a refund, which they gave me. The lead maintenance guy said the oil level was fine. I told him the oil had to be pure and new or it wouldn't pull the vacuum it was rated for, not even close. He said the oil was fine, they had topped it off before renting it to me. I said the vacuum chamber relies on a very clean and pure oil. He said the oil is only for lubricating the pump. I said no, it is also used in the vacuum chamber to pull the deep vacuum and he started walking away fed up with me. So I said "Fine, don't listen to me. That's why the pump doesn't work." He stopped and said it does work and walked away. Later I called the manager and described how the maintenance guy doesn't know how the vacuum pump works and the need for clean oil, he said he would talk to him and make sure he understands. It would be nice to send that maintenance guy a link to this video lol.
Vacuum Rotary pump oils are Hygroscopic not Hydroscopic. I'm Sorry if I sound like a Pedantic Knob-End Wanker. But if you get a question in an exam about water vapour absorption in the oil, the difference between a "G" and a "D" as in HYDRO or HYGRO could be affect your results. Great video. Stay safe my dear American Cousins. 🇬🇧🇺🇸👍🇬🇧🇺🇸👊❤️🇬🇧.
So how do the fieldpiece vacuum pumps work if the oil is in a separate container. The oil is not inside the machine and you can change it while it is running.
Great Information. Sounds like a great vacuum pump.
