Nice size for epoxy debubbling, with a decent pump it works pretty quickly. Lid seal seems to be sturdy and haven't had any issues so far.

This worked really well for vacuuming silicone molding material before pouring. Because of the other reviews, I did use it outdoors, but I didn't detect any spewing of oil into the air. I did purchase non-misting vacuum pump oil to go with it. The directions that come with it aren't great, but I was able to figure it out, in particular, where the air filter was supposed to go on the air intake valve. It's important to open and close the valves in the proper order, and to practice first before you mix up your solution and turn on the pump. 1. Close air intake valve. Open vacuum pump valve. 2. Turn on pump until the needle stops moving. 3. Close vacuum pump valve. 4. Turn off pump. 5. Wait. Chamber maintains the vacuum. 6. Open air intake valve. 7. Repeat as needed. "Close" in this case means, "turn the valve handle toward you, at 90 degrees to the pot" and "open" means "turn it 90 degrees in the other direction, parallel to the hose."

Great unit, like everything about it except for how the valves go through the wall. THere are a couple flimsy orings and the whole valve assembly just flops around. I was able to tap it for ⅛" npt (or ¼", I don't remember right now) and it held well against a gasket, so I was satisfied.

I'm new to vacuum degassing. I did some research on products and settled on the Bacoeng setup. I originally was going to get a smaller chamber but decided to spend a bit extra on the 1.5 gallon size. I'm glad I did. It fits a decent sized container or several small ones for degassing and having the gauge on the side leaves the glass top clear for viewing the process. It's fun to put marshmallows in and let my 7yo learn some things. It holds the vacuum really well. I pulled it to -29.5 and left it for 24 hours and held without issue. The glass lid is heavy and it seals quickly and the chamber walls/floor are thick and sturdy. The gauge and valves that come with it are sturdy and work very well with the chamber and the silicon mat is thick and appears very well made. It's packed really well and arrived quickly with no damage. If I had to nitpick on something, it would be the rubber washer used for the gauge on the inside of the chamber. You've got to tighten the inner nut quite a bit to squish the washer enough to ensure it seals properly. See picture. Having a thicker washer, or maybe one that's a bit more solid would help it seal a bit easier. Otherwise 5 stars all around.

I am of the mindset mistakes happen, but having 3 easy to spot manufacturing errors happen at once is just silly. When I found the pump I ordered was missing the gauge and glass that keeps the oil from spilling out I chalked it up to just a freak mistake. I contacted the seller and after a few days got a response and they issued me a $90 return to buy new pump locally (or they offered to replace it with a new but weaker airpump). I felt like I was loosing some money but was easier then mailing back everything, besides I really loved the design of the tank and the lid, looked very nice. After getting the new pump I hooked it in and realize the entire setup for tank free rotates with no way to safely tighten the nut (seller advised againts it). Also the air release/intake handles were put on backwards so they hit the tank when you try to open them. While on most things I would grin and bare it and try to make this work, this is a tank that could implode if it was faulty so didn't take the risk and refunded whole thing. In short, 3 different manufacturing errors (one of them being completely detrimental). The only good part about this was how nice the tank itself and lid looked and how friendly (but on script) the sellers were. But sellers took about 3 days for each reply which made communication unpleasant. I almost reaordered a new one cause what were the chances of having more defects, but I was too spooked too. I really did wish I could've have used it in the first place.

I was a little worried about buying this for my resin projects. Seems some of the reviews are hit and miss. I took it out of the box, put in the oil and pulled a vacuum. What you see on the dial in the picture is what it stayed at for the whole time for 24 hours! Never moved. I know I have a good seal and the pump is working. A couple of things... 1) It came with a filter (see picture) but the manual doesn't mention where this is supposed to go. FYI the manual is pretty good for the most part. 2) Came with oil and the whole bottle filled it to about the middle of the min and max marks but when it was pulling a vacuum I could see either a mist or a bit of smoke coming from the top of the fill cap. Not sure this is normal but it still pulled a vacuum. 3) There is a thin mat that comes with it (see picture) but again I have no idea what this is used for. 4) The gauge and valve mount are a bit flimsy as it just goes thru the side of the pot and then a nut holds it on. I had to crank mine down a bit to secure it. They do give you extra rubber washers (seals) so if they are damaged you can replace them. All in all it looks well made and works. Came well packaged too. Can't wait to put it to use.
