BACOENG 3 Gallon 4.5 CFM Tempered Glass Lid Vacuum Degassing Chamer and Pump Kit, Perfect for Stabilizing Wood, Degassing Silicones, Epoxies and Essential Oils

Product was well packaged and arrived undamaged. All documentation was present in packaging.Setup was easy requiring only open end wrench to align and tighten gauge/valve package mounting nut on inside of chamber.Glass top and top seal were clean and defect free. Stainless steel tub sealing surface was smooth without dents or scratches. Included hose has tool-free brass connectors w/gasketing. Easy and quick to install/remove. Hose has sufficient length.Liquid filled vacuum gauge was easy to equalize for ambient pressure prior to use with vacuum pump. Equalizing insures proper vacuum chamber readings.Vacuum pump was easy to fill with oil and initial startup was uneventful. Vacuum of 29.5 in.Hg obtained in <3 minutes. Chamber valves were closed, pump shut off and hose disconnected from chamber. Vacuum still at 29.5 in.Hg after 2+ hours. Impressive for a single stage pump.Would recommend to any other customer.

We use our chamber for vacuuming out bubbles from resin mixtures. It does exactly what it's supposed to with no complaints, but it did require some initial troubleshooting. There were a few helpful tutorials for this model I found on Youtube. Here's What you need to do:1. There's a black rubber gasket on the top of the gauge. In order to properly adjust to your local atmospheric pressure it needs a small hole poked in the gasket. I used a small exacto blade. Be very careful when doing this. The gasket can easily slip into the gauge and it will be unrecoverable.2. Push down firmly on the lid when starting the pump. I hold it until it the gauge reaches 2.5, at which point it will keep climbing to 30 on its own.We put the pump on a styrofoam block with foam underneath. This really helps dull down the pump noise since we use it indoors. The pump spews out so much oil vapor so we attached a clear hose to exhaust it out a window. It works like a charm.Overall it's a great kit for the price. We use it at least twice daily and it's been running strong for about 6 months. At the price point it made its money back long ago. We'll keep changing the oil regularly and hope it lasts.

Overall I am pleased with this purchase. However the pump spews a good bit of oil mist into the air as it works. I have even drained all the oil and refilled to ensure it wasn’t over filled, but I still have tons of vapor.

I replaced my previous vacuum chamber which had a plastic lid. I mostly use the chamber for stabilizing wood, and that destroys the plastic lid. As a bonus, this chamber has the gauge in the body of the chamber so it should be easier to reseal if necessary.The pump is a big step up from my previous pump. It's quite. But faster than the old Zeny I replaced. It also will fit most AC manifold gauge sets (including HF) out of the box. My old unit required an adapter to fit.My only complaint about the unit is the gauge rotates with the hose. But it will hold -30 inHG overnight, so its not leaking.

Works very well and pulls a vacuum fairly quickly. I've only had it for about a week or so, but I'm happy with it.My only complaint is that it puts out a lot of mist... So much so that I thought something was wrong. It filled half my shop in a misty fog in about 3 minutes. Not only was I apprehensive to be in my shop breathing in the fog, I was also wondering if it was sticking to my walls and tools in the area. I didn't notice any residue and was about to return the unit when I saw that people were saying that they drained the pump oil and replaced it with a non misting pump oil. I ordered a bottle of oil and replaced the oil today and I'm happy to report that there is no longer a cloud in my shop when I run the pump.They should ship this thing with non misting oil. It would literally cost them about $5.00 more to do this.Overall I'm happy with the pump and chamber, and would have given 5 stars if it wasn't for the oil issues.Do yourself a favor and order the replacement oil when you order the pump so you don't have to wait additional days to use it.
