Review: Great vacuum pump for HVAC work - I use this Robinair pump for mini split and central A/C installs. It pulls vacuum fast, runs quiet, and feels solid. Very reliable tool—highly recommended for any HVAC tech.
Review: brake it in and change the oil again !!! it will make a big difference in your experience with the pump - I have read some of the reviews of how the pump is used and the oil turns black or spit out oil i can say i did experience the oil turning a little dark but ive bought the pump with new Robinair Oil and followed the instructions, ive also let it ran 10 more minuets after the initial brake in period just to make sure everything worked well. ive changed the oil after and let it ran again to see if it was just old oil that came with the pump or if the pump was actually burning or was defective. i am happy to say that it was just the oil that came in the box. ive used it for 2 hours on a job and checked back and the oil is still some what clear but is understandable seeing how the AC system had a lot of moisture so the oil would look a little cloudy, changed it and started on another job and again no problems had a strong vac micron levels were where it should be. the oil that "leaded out" was dude to a very slight over fill of oil after ive adjusted the level no issues at all. my advice is to fill the pump up to the point were the edge of the oil surface tension reaches the sight glass line doing so in my case seems to fix the spitting oil out the exhaust filter, if you cant get it just right i dont see any reason to make a small extension to compensate the oil spitting out the exhaust filter, over all if your a DIY or dont know how to use a vacuum pump or service it ask some one for help because this pump works very well for small to mid side jobs. the only thing i want this pump to have was a larger oil capacity for a longer run time so i dont have to stop it and change the oil as often dude to the high humidity area where i had used this pump in. for the price you pay for it your getting a pretty good deal, most likely buy the 8 cfm in the near future just to save some time hope this helps someone.

## Questions & Answers

**Q: Can the exhaust fitting (the big red plastic cap) accept a pipe fitting?**
A: The exhaust fitting does not accept a standard NPT fitting, the exhaust female thread is 7/8" in dia and 16 tpi.7/8" ID lies between pipe size 1/2 and 3/4

**Q: Can you tell the rated hp for this pump? I need one to easily keep 11 lbs vacuum using a pressure guage. Thanks!**
A: Bonnie - 1/3 hp. It will hold 28 to 30in Hg in smaller sealed systems, such as automotive AC. Note that vacuum in this unit is constant and increases up to about 30in Hg. The equivalent in PSIa (a = absolute) for 30in Hg is roughly 15 PSIa. Note also that you will require a vacuum gauge to monitor vacuum; not a pressure gauge. Hope that helps.

**Q: Can i use different brand oil? Or has to be same brand?**
A: Any brand of vacuum pump oil can be used.

**Q: What is the Warranty on this pump?**
A: It has a Limited Warranty for 1yr from dat of purchase

### ⭐⭐⭐⭐⭐ brake it in and change the oil again !!! it will make a big difference in your experience with the pump

I have read some of the reviews of how the pump is used and the oil turns black or spit out oil i can say i did experience the oil turning a little dark but ive bought the pump with new Robinair Oil and followed the instructions, ive also let it ran 10 more minuets after the initial brake in period just to make sure everything worked well. ive changed the oil after and let it ran again to see if it was just old oil that came with the pump or if the pump was actually burning or was defective. i am happy to say that it was just the oil that came in the box. ive used it for 2 hours on a job and checked back and the oil is still some what clear but is understandable seeing how the AC system had a lot of moisture so the oil would look a little cloudy, changed it and started on another job and again no problems had a strong vac micron levels were where it should be. the oil that "leaded out" was dude to a very slight over fill of oil after ive adjusted the level no issues at all. my advice is to fill the pump up to the point were the edge of the oil surface tension reaches the sight glass line doing so in my case seems to fix the spitting oil out the exhaust filter, if you cant get it just right i dont see any reason to make a small extension to compensate the oil spitting out the exhaust filter, over all if your a DIY or dont know how to use a vacuum pump or service it ask some one for help because this pump works very well for small to mid side jobs. the only thing i want this pump to have was a larger oil capacity for a longer run time so i dont have to stop it and change the oil as often dude to the high humidity area where i had used this pump in. for the price you pay for it your getting a pretty good deal, most likely buy the 8 cfm in the near future just to save some time hope this helps someone.

### ⭐⭐⭐⭐⭐ Excellent build quality and very quiet compared to other cheaper, lower rated CFM pumps
*by S***E on June 21, 2025*

Very high quality pump. I've owned others and not only could I tell an immediate difference in build quality by how heavy and well put together this pump is compared to the others but the quietness and deep vacuum ability are unparalleled. I live in the NE heights of Albuquerque so my elevation is around 5400ft (1645 meters) above sea level. Most people forget to calculate elevation into the amount of mercury your able to pull but I'm here to tell you it factors a GREAT DEAL INTO IT. For instance at my elevation I'm only supposed to be able to pull 25inHg with a vacuum pump that pulls 29-30inHg at sea level (San Diego, CA for instance). So if your at a high elevation like me(Denver for instance) and can't understand why your vacuum pump rated for 29inHg is only pulling 25, it's not the pumps fault (more then likely). Bc the higher your elevation the lower the available atmospheric pressure. Why the meteorology lesson you say?! I'll get to the point. Even tho this pump is technically only able to produce 25inHg at 5400ft it was consistently producing beyond that teetering between 27-28inHg which along with the build quality and quietness of the pump should make you not even consider the cheaper pumps (which I wasn't able to get more then 25inHg from) and spend the little extra money on this. I've had for about a month and a half at this point and used it to pull vacuum on 3 different vehicles (one of which I've pulled a few times bc of how old and long it was open to the elements) and the oil is still really clean. I did just get my replacement robinair oil tho- 2 quarts~$20 on Amazon so I'll be replacing it before the next run-also bc it is a tad low. I'll update review as it gets older if I have any issues but based on build quality and the maintenance I'll give it- I don't suspect I'll have any. Sorry for the winded review! Hopefully it helps someone!
