Make sure you read the directions properly when adding oil. You don't just add oil until it reaches the oil fill line. You must turn the pump on, take off the exhaust fitting, and close one of the caps, and leave it running for one minute. After that one minute the oil level should be where the oil is actually at. So you need to run it for a minute to check oil levels, but other than that this thing can run for a long time and will get hot. Not a problem though cause this thing was designed with heatsync technology and stays cool everywhere else except for a few places.
All in all I loved this thing way better than the lower model and it was CHEAPER. Get this thing if you need a pump to pull -30Hg and beyond.
It will not only pull and remove all trace gas from your material but also pull all moisture from your material also. If you run concentrates, then you have stumbled onto exactly what you were looking for! Save time and order yourself a quart of the vacuum pump oil too, youll need it after a few vacuum runs. Change your oil when you notice it starting to get too discolored. After all, its the lubrication for some highly precise veins spinning inside under tight tolerances.
They returned the pump and sent me out a new one RIGHT AWAY. It works great and good value for the money .
Although there was the hassle in getting a pump that did not work and having to go through returning it,(these things happen).
Amazon's well thought out return system kept My Stress Factor to a minimum.
I Thank Amazon for a great customer service experience even under these circumstances!
When it arrived I noticed something strange. It had thick dark golden oil in the oil sight, right out of the box. I flipped through the instructions (i have never seen this before in a "new" pump) and sure enough in nice bold dark print the Robinair Owners Manual states "item ships without pump oil" and to add pump oil before the inital use of the pump. This residual dark oil freaked me out mostly because the oil Robinair itself sells for use in its pump (and the only oil I use) is almost perfectly clear. The oil in my pump looked more like honey than pump oil. So i drained the pump and refilled it with the new robinair oil included with my pump and tested the pump on my chamber for barely an hour. The pump worked well at first pullling the vacuum to close to 29, then as I let the pump run I noticed to hear a whine or stress sound coming from the motor of the pump, and then it just up and died on the stop, probably within 65 minutes of me pulling it out of the UPS box. Now the reason I wrote this review is because I feel that after examination of my pump, the weird gunk in it when they shipped it to me, and its performance compared to my funcation 8cfm pump, I concluded that this "new" pump has seen way more wear and tear than my old pump. Noticeably after running such a short time the "new" pump has already given the pump oil a burnt smell.Read more ›

Still going strong, able to pull 500microns easily! Highly recommend for 5ton and up units. For split ductless, this is over kill and HEAVY. Read morePublished 3 days ago by Keith Adelbai

A beast of a pump! Pulls down fast and is very quiet. Great quality. I'm a hobbyist so this should last me a lifetime as it won't be used as often as in a revenue shop. Read morePublished 5 days ago by Amazon Customer
Bought this about Sept/Oct 2015 and have only used it 3 times. I went to change the oil before a job today and it won't even turn on. Read morePublished 24 days ago by Michelle I.
