VIVOHOME 1.5 Gallon Vacuum Chamber with Pump, 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.

Why did you pick this product vs others?:Works great! Buy some extra oil.

QA needs some work. You get what you pay for. First item developed a heavy backflow leak of oil that emptied the reservoir. Researching online suggests there was a faulty gasket inside of the pump. Easy enough to replace if you're handy with tools, but since I was within the return window I sent it back and requested a new one. Replacement unit works great, zero issues. Only minor complaints now. First, the screwdriver that comes with it is a size too small. Second, the valve screws are not machined tightly enough to handle pressure. They give you some tape that you're supposed to use, but you'll want to buy some Thread Lock before assembling.

sweet 👍

I used the 4 times and then it developed a leak around the guage. I could not find the leak and could not find replacement parts. When I closed the valve between the pump and the camber I got vacuum. So the hose connections were good. I tried tightening the nut holding the guage and the silicon gasket deformed. I tried other gaskets and then tried jb weld around the base of the guage - nothing worked. I will not buy another one from this vendor.

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.

The vacuum chamber held up pretty well the first few uses but after enough uses the bottom took some deformation. I use this for epoxy resin and the bottom is no longer level so things are turning out kinda lopsided sometimes which is a problem for what I'm doing. The chamber and pump do pull nearly a perfect vacuum and I haven't noticed any leaks so if you don't need the bottom to be flat this is a good chamber

Fast pump down to reduce the amount of air trapped in uncured resin.
