Review: This is a Great Vacuum Pump for Winemakers - Every winemaker should get this vacuum pump. If you aren't familiar with Wine Degassing, you can read more online, but in a nutshell, "degassing" wine removes the CO2 that is created when sugar converts to alcohol. When you leave CO2 in wine, it tastes bubbly, and leaves a foul flavor. I've tried several other products to degas my wine before looking at an actual vacuum pump: * A handheld vacuum, often called Wine Pump or Vacu Vin. This is a six-inch tall pump with a rubber stopper designed for removing the air from a single bottle of wine. This works, but only pulls up small bubbles and takes a lot of effort to get a very small result. * A metal rod wine whip. This is a straight metal rod with two plastic flaps at the end that you attach to a power drill and stick into your wine bucket or carboy to spin the wine around and stir up the bubbles. This was essentially, for me, an electric version of the Vacu Vin. Not much of an improvement, and took a lot of time. * A Wine Whip degasser. This is a C-shaped plastic rod (much like the metal rod) that you also attach to a power drill and stick into your wine bucket or carboy to spin the wine around and stir up the bubbles. It works pretty well, better than the metal equivalent in my case, but takes a lot of time and only gets slightly larger bubbles than the Vacu Vin. * A Vacuum Sealer. This is a completely different product. These are used to vacuum seal food. There are a lot of examples online using a Vacuum Sealer that use the accessory port (normally used for things like sealing Mason Jars) to degas the wine. I haven't tried many of these, but my Vacuum Sealer had a safety mechanism that shut it off when it hit a certain amount of pressure, so I had to restart it over and over. In the end, it never got more than small bubbles. So I started looking for a proper Vacuum Pump; no shortcuts, just a real electric vacuum pump. If you've looked at these much, you probably know that they are pricy. Most of the local big-box stores didn't even carry them, and even the few that did started over $100. At the time that I purchased this unit, it was $48 plus about $10 shipping. I researched the different types of pumps: single stage, dual stage, etc. For Winemaking, a single stage looked like it was going to do the trick. The main advantage that I found in this research was that a dual stage would eventually be quieter as it was running. However, this vacuum pump isn't loud at all. I measured the decibels that it put out after warming up. With the decibel meter 6 inches away from the pump, it produced 64db. This is pretty low, in my opinion. This doesn't sound like an air compressor; it sounds more like a washing machine, dryer, but probably closer to a dehumidifier. This is not loud at all. The vacuum power on this is more than enough for a 23 liter (or 5-6 gallon) glass carboy. You are supposed to put another drip container in between your carboy and the vacuum pump when you start. I had read about how important it was to make sure that you don't get any wine or fluid into a vacuum pump, but having tried the above mentioned methods, I was expecting a slow start when I plugged it in, so I hurriedly skipped adding a drip container, but was ready to pull the hose off in case it started to fill the hose with wine. I am so glad I was ready. When I first turned it on, it degassed so fast! Bubbles shot to the top and wine was in the tube faster than I expected, and I was able to rip the hose away from the pump in time! But be careful, this thing can degas quickly. After that, I connected a drip container and turned it back on and it is pretty amazing how well this works. I was using spare hose, not air hose that is reinforced, so the hose and tubing collapsed on itself and pinched, slowing down the airflow. Tomorrow I'll be heading out to get proper air hose, a relief valve, and probably even a regulator so I can monitor the pressure. This thing works very well and is a great deal!
Review: Mine makes a mess in the vicinity of the pump. - I purchased this 1 year ago. It’s probably seen 3 hours of use in a half dozen different operations to cure cf and fiberglass. Its been perfect but it uses a fair amount of oil. Being my first vp, I don’t have a baseline for comparison so maybe that’s normal? The consumption isn’t as much a problem as the fact that it exhausts the oil vertically in a 1’ diameter around the pump exhaust. I sit it on a platform of shop towels to absorb some of the oil. The included oil has been used and it’s almost at the low level again so time to buy more. Again, it does the job and for the cost I can hardly complain but it makes a mess. I learned that after it oiled a bin full of fiberglass cloth which of course makes that garbage. This may have improved in the year since I bought it and maybe that’s not the norm but that’s the experience for me. I’d buy again unless better ones don’t exhaust the oil in which case I’d spend the money. Assuming that is the norm I have no complaints. If that is typical I can hardly dock it so the 5stars is based on my ignorance of an appropriate expectation.

## Questions & Answers

**Q: will this work for stabilizing wood in a vacumm chamber? Thanks**
A: That is what I use it for. I am at 1700+ ft elevation and pull 27 Hg on my gauge.

**Q: Where can i get the oil for this?**
A: It comes with about 250ml of oil

**Q: Will the pump pressurize to test for leaks in addition to pull vacuum?**
A: you can check for a large leak with it, when you vacuum the refrigerator you will have about 14.5 on the monometer, turn off the pump and wait 2 minutes, if the pressure drops much below 14.5, then there is a hole in the system

**Q: I bought one 2 years ago and put it away. now that i need it i can't use it. i found out that i bought a r10a instead of a r134a. do they sell adapter**
A: I had  the same problem,  I found a adapter at a refrigeration supply .

### ⭐⭐⭐⭐ adequate for 16 feet of line set or shorter
*by O***Y on July 10, 2020*

This pump pulled negative 30 psi for a 16 foot line but never reached 30psi for a 25 ft line. I didn't use a schrader valve remover tool and that is something I would do differently since the obstruction might've made a difference. I simply don't trust the pump was strong enough to pull a strong vacuum on a 25 foot line, (50 feet if you add both lines)..... But it worked flawlessly, never leaked, never smoked. I ran it for 4 hours on a single line and it all held negative 25 psi, but didn't reach negative 30 psi on the 25 foot line. If I had a 16 or 10 foot line I would use it again, but for 25 feet of line I think it leaves humidity and air in the line. I didn't use a micron gauge so I don't KNOW, but I suspect it left humidity in the line, although the two units are up and running very cold air. I don't see any bad effects from using this vacuum pump on two zones, but I suspect it was not 100% successful in removing all humidity and air. It was maybe 95% successful. That's my suspicion and I can live with it and the units are working fine. If money is no object then definitely buy the $200 pump with 2 stages and more cfm and a micron gauge and a schrader valve core removal tool. Yes, the $400 will probably be worth it. If you have more time than money then run this pump for 6 hours or even 10 hours if you monitor the oil level and if it holds the vacuum then let the refrigerant into the line set and live with it.
