BACOENG 1 1/2 Gallon 3.6 CFM Vacuum Chamber with Pump, Degassing Vacuum Chamber Kit for Resin, Not for Stabilizating Wood or Making Fish Baits

This is my first degasser- I've read a lot of reviews and seen it in action in various YouTube videos- If I was going to say anything about it- the glass top was very smugged up, the top didn't seem like a previous return but you never know- other than that it works good.

Like everyone else in the market for a vacuum chamber that will work well without breaking the bank I rely on reviews and this one had me really unsure because it seemed like a lot of reviews mentioned the glass top arriving damaged or getting cracked easily with use. I can say that I haven't had that experience. Been using this every day for a couple of months and have not had any issues. This worked right out of the box and was very easy to set up and maintain. I use this for degassing platinum silicone and it works like a charm. Highly recommend if you're looking for a budget-friendly degasser that will actually get the job done.

I had a bit of trouble at first since my order didn’t show up, but I have to give credit to customer service. They did worked well with me to get a replacement pretty quickly. I had it in hand within a day or two, which was super impressive. When I first started using the vacuum chamber, it worked pretty well. The pump pulled a good vacuum, and everything seemed solid. But after a while, the seal started failing, and air slowly leaked back in, which was frustrating. The pump itself is fine, but the chamber definitely needs a better seal if you want something long-term. I’m using it for making resin dice, and while it helped reduce bubbles, it didn’t get rid of them completely. I’ve since learned that I actually need a pressure pot for that, so that’s on me. Overall, it’s a decent setup, especially for the price, and the customer service experience was great. Just be aware that you might need to tweak or replace the seal if you plan on using it a lot.

The lid cracked after being at negative 1 Bar for 8 hours on the first use. The valves, gauge, and vacuum pump seem to work great and it's a decent size. For the 8 hours, the whole system worked great and allowed me to nearly complete one round of extraction. Unfortunately I only got one use out of it before it became completely unusable. As a bonus, my dog peed the bed from the incredibly loud noise it created at 4:45 AM so it robbed me of a good bit of sleep too.

Good quality for non professional use. I took the pump apart to check the build quality, and it looks very good, no burrs or metal shavings left inside. The hose is very good quality compared to other brands. The vacuum chamber seems to be as well built as any other, and I haven't had problems with leaks. I should mention, the oil it comes with is not very good. It creates an oil fog, which is bad to breathe and can contaminate your projects. I solved the issue by replacing it with TSI Supercool 46 viscosity vacuum pump oil. Seems to be the same viscosity, and solved the oil fog.

I'm loving this for removing bubble from epoxy resin. I did learn how to use this from YouTube videos. I don't know why they can't send clear cut instructions for the price paid. Anyways, after using it a few times I now have confidence in the product and I am not intimidated anymore. It is really good quality. I am just wondering why it leaks a little bit of oil around the cap? Hummm? That has not impeded the operation of the machine though. I did go ahead and buy more oil to have on hand as the bottle it comes with is just enough to fill to the operation line in the tank. Well packaged and shipping was acceptable from Amazon Prime.

Works great for what I needed to, but still can’t achieve a perfect vacuum. In my case that’s exactly what I need though so that’s fine it’s right below a total vacuum maybe 1 inch of mercury left of pressure. Compared to atmospheric pressure which is about 30 inches of mercury. (so it can achieve 1/30 of the pressure in the air which is enough for me, in my experience with it at least) Changing the oil is nice and easy

Best thing i could have bought to use with the risen to get bubbles out! Easy to use the size is great for small things or cups. The best value for the money also!
