VIVOHOME 5 Gallon Vacuum Chamber with Pump, 304 Stainless Steel Vacuum Degassing Chamber Kit with 3.5 CFM 1/4 HP Single Stage Vacuum Pump and Oil

Product--- VIVOHOME 1.5 Gallon Vacuum Chamber with Pump. This kit works great!!!! Assembly was quick and easy. 1 install the gauge assembly on to the clear top. 2 place the silicone ring around the top. 3 fill the vacuum pump with oil. 4 connect the hose from the gauge to the pump. This kit was up and working in maybe 10 minutes. Vacuumed the chamber down and had no problem holding vacuum for .5 hour. After initial test released vacuum and tested degassing liquid as seen in the photo.The little issues I noticed with the kit I received:1. The gauge seems off and does not return to zero (when unboxing it the kit, the gauge was already at 5. This is not a problem for me as I don’t need accuracy for my task) probably should give zero stars for accuracy.......oh well..........2. The pump has a hard time starting when under full vacuum. It did start, but it took a second or so to get to full rpm. Easy fix with the pump side of valve closed release the vacuum in the line by opening the cap slightly at the pump. Than close cap and start pump and slowly open the valve for pump side of valve to increase vacuum in chamber.This is a budget friendly kit and work very well. I am very happy with this kit and it works perfectly for my tasks.

I am loving it, one month in - reliable, goes all the way to -30. One tip - do not use in cold environment as the silicon lid ring might not hold the pressure well.

I filled the oil as instructed, halfway between min and max. After running about 10 minutes I noticed oil splatters on the floor around the pump, significant oil on top of the outlet muffler, and even a slight haze in the room presumably from oil mist.To be fair, the vessel I was attached to was not airtight (only achieved about -11 psi) so there was more airflow than normal. Also, there is a very large range between max and min oil level, so I should probably run it closer to the "min" level and it will probably stop spitting oil. I've used other pumps before that seem to like the oil level on the low side.On the plus side, when using the stainless steel chamber that came with the pump (which has no leakage) the little pump sucked it down to nearly full vacuum within seconds, and I could turn the pump off and the vacuum would hold so there is no leakage. I did not even use the included hose clamps, just pushed the vacuum hose onto the barbed fittings.The pump runs quiet and smooth.Also nice is that the lid of the chamber is clear plexiglass, so you can keep an eye on what your degassing.The gauge, fittings and hose all seem pretty good quality.As others have mentioned, the instructions are strange and confusing. But everything is obvious, I recommend through the instructions away and just figure it out yourself. Its not hard.

Not sure why some of the bad reviews I saw on this item. I looked at several vacuum chambers for resin including this one and decided on this item. When I received it I read the instructions and used the included teflon tape on all the fittings that you screw in. I added the oil to the proper fill line and ran a test vacuum, and it worked great. I then mixed up some residual for a project and placed my form inside the vacuum pot and placed the lid on and pulled a vacuum. The vacuum held without any issues and did not lose any vacuum. I released the vacuum and pulled the vacuum again and this time let it sit overnight, when I checked in the morning the vacuum had not lost any of the vacuum from where I left it at, 29 bar. I am very impressed with this product and would buy it again. If you want to good vacuum chamber for resin or other projects don’t hesitate and buy this vacuum chamber. I was hesitant because of the few bad reviews, but this vacuum chamber does the job and does it well.

Not only did the lid crack, but it cracked with about $100 worth of deep pour resin inside so now I have a total mess and a huge waste of money

Why I didn’t purchase this before. What a difference when you remove the bubbles from epoxy. Perfect size and easy to assemble and clean.

I recently (4/2025) received this vacuum pump set to use for removing air from mixed epoxy resin. The kettle is sturdy, the pump is adequate and the fittings are all well made. My only issue is that the top does not seal well to the kettle. The instructions indicate that there is a rubber gasket that gets attached to the kettle, but this was not included in my kit. When starting the pump, I need to push down firmly on the top and hold until the vacuum finally seals. Once sealed, it holds the vacuum well and removes the air as needed.

I was pleasantly surprised when I opened the box and assembled the unit. Every part of this unit was very high quality. The top was very think glass, the pressure gauge was glycerin filled and the pot high quality stainless steel. I vacuum tested this unit and it held very well!!
