VEVOR 3 Gallon Vacuum Chamber and 3.5 CFM Pump Kit, Stainless Steel Chamber, Single Stage Vacuum Pump Degassing Chamber Kit, with Acrylic Lid, Oil, 4.92 ft Hose, for Degassing Resin Silicone Epoxies

Extremely simple to use, self explanatory setup and operation, especially with my 1/4 hp matching vevor pump. The rubber ring for the lip doesn't really stay put, but it's unnecessary for maintaining a high vacuum for long periods of time. I can pull it down to ~.01 atmospheres and it will not move from there for weeks with no leakageThe lid is heavy and extremely thick. The pot itself is the bare minimum thickness but still fairly sturdyVevor isn't the greatest pick for high build quality tools, but everything I've gotten from them is functional and economical. Strongly reccomend

Just got my hands on the VEVOR 5 Gallon Vacuum Chamber, and let me tell you, it’s a game-changer! Finally, a vacuum chamber that doesn’t make you feel like you’re wrestling with an octopus every time you use it. The tempered glass lid is super thick but crystal clear, which is perfect for checking on my degassing projects without needing to open it up every five seconds. And the 304 stainless steel body? Genius. No more worrying about it rusting or losing its shape when I accidentally splash some resin around.Now, I’ve been into wood stabilization and resin casting for a while, and I’ve always had my woes with bubbles ruining my stuff. This chamber has a 24-hour airtight seal that really lives up to the hype. The vacuum gauge gives solid, precise readings, and the shock absorption from the silicone oil was a nice surprise too. I could finally control the airflow without feeling like I was juggling a dozen things at once. Seriously, if you’ve struggled with leaks in the past, this one’s a breath of fresh air—hardly any noticeable leak rate over 12 hours? Sign me up!I can't even explain how much easier my crafting life has become since using the VEVOR vacuum chamber. The noise reduction feature on the intake valve is a sweet bonus too—no more waking up the entire neighborhood when I'm working on my next masterpiece at midnight. If you're into degassing silicone, resin, or stabilizing wood, trust me, this is the tool you've been waiting for. It’s so easy to use that even my cat ponders taking a stab at a new hobby. Grab one, and let the creativity flow free!

Works great. Good packaging. Seems like good quality. When using it, be sure to push down on the lid at first so it gets a good seal for the vacuum pump. Directions were semi-clear, but not difficult to figure out. Comes with the proper tools to put it some of it together.

This got the bubbles out of my resin well. It was simple to set up, performed well, and looks very nice. It's solid and easy to clean, as well as large enough to not need anything else to expand my hobby casting. It didn't leak air, and was a very reasonable price for the options it opens up for my casting.

Hard to get a seal unless I put my weight on the lid to get it started. Pressure doesn’t hold. Notified Vevor support and they asked for pictures. However, the email with pictures was rejected. I’m on a tight timeline and need this to work. Any suggestions?

It came packaged perfectly no problems putting it together but, it’s kind of hard to get the proper seal in the lid in order for it to remove air. Also the pump doesn’t turn on I have to turn it off and back on a couple of times. Once the pump turns on and I press down on the lid it does work as expected

Great item. Holds vacuum. Get down to -30 in a min or 2. Make degassing a breeze. The lid was the selling point for me. It’s a thick piece of glass which def helps create a seal. All in all a great purchase for my needs.

Does exactly what you need. Vevor stays reliable. Easy to setup and pressures up within a minute.
