VEVOR 3 Gallon Vacuum Chamber and 3.5 CFM Pump Kit, Tempered Glass Lid Vacuum Degassing Chamber Kit, Single Stage Vacuum Pump with 250 ml Oil Bottle, for Stabilizing Wood, Degassing Silicones, Epoxies

This was likely the least expensive in the 3-gallon category. I bought it for the price, sold by Amazon and the effort I made to find one with a more detailed, better description. I did a lot of research; they all appear to be the same just more money. I would have spent more for a definitively better pump. Something a bit faster.What I got will go down to 27 on the gauge but it takes a few minutes. Considering my elevation is 1,182 feet my barometric pressure 28.7 I think this vacuum chamber works very well. I have not noticed any oil misting. Assembly was easy,

Had to rate this is only for what’s received. Operation will come later.Received:I wasn’t expecting much based on reviews. For me it’s packaged well, everything seems to be substantial, came with oil; many complained no oil came with their unit and I received an instruction booklet.So far so good, not a fan of orange but that’s a football thing. More to follow.Part II: Put it together, exceedingly simple, tested and it worked like a champ, took no time to vacuum down. Parts go in the bucket easy to store.Hopefully this weekend I’ll have part III. Actual results w/ epoxy pouring, remove the bubbles.Follow up- too easy to use. Work perfectly vacuuming does Epoxy Resins super quick and effective. Removed all the bubbles.Note: Watched a lot of videos on this unit and others the key is to introduce a little air for the last few bubbles, shut it down slowly allow vacuum to build back up might do that twice. And when there’s only a few bubbles left, very slowly release vacuum while opening the atmospheric ball valve at the same time. Key be gentle handling the releasing of ball valves very slowly and gently. Like Bruce Lee said be WATER.

My vacuum pump works fine. A little slow but gets the job done. It does emit a fog of oil from the exhaust of the pump. Just to set the record straight, I have used lots of vacuum pumps, as a mechanic. They all emit a fog of oil from the pumps. Even my $2600 lab pump, does it. Ok, on to the vacuum pot. The pot is fine. The lid is a place of potential fast failure. It seals with a very soft and STICKY silicone gasket. If you don’t keep it clean. It will stop sealing. EVERYTHING sticks to the seal. This belongs in a clean room, not a shop. The lid weighs a good bit, there are not latches or any mechanical means to “tighten” the lid down. It depends on gravity and a very clean seal. Mine works, it does hold a vacuum, I suspect that dirt will eventually end up in the seal, and then it will be useless. Be warned, keep it immaculate.

I did have a small problem but customer support was able to fix the issue really fast. Overall great product and awesome customer service and care

Only JUST got the product working, no thanks to the documentation or customer service.I have not directly operated a vacuum pump before, nor ever worked with any kind of small engine other than replacing oil in a WELL DOCUMENTED place - but I have a strong engineering background in other fields.Box supplied 2 bottles of oil and documentation did show where the oil LEVEL was, but didn't tell you that it would need both bottles, nor WHERE TO PUT the oil. The cap labeled "Oil" was not obvious whether it was for adding oil, checking its quality etc. INCREDIBLY sparse documentation wouldn't say. I added a full bottle under the oil cap and the level indicator did not move.I Sent question to seller who wanted pictures (which is to say, didn't even at the question itself), and wanted to upload them through a third party.Web searches were fruitless as well. The closest I got was for a Vevor GAS vacuum pump with approximately the same form factor and seemed to have the oil intake in the same place.I added the second bottle to that place 80% sure it was the right place, and the oil line on the level system did indeed rise to the obvious level. I would certainly be returning the product if that had turned out to be the wrong place.The pictures of how to lay out the piping and valves were not clear, but I guess they provided something. Certainly they were keeping their language translation to a minimum.When I operated the pump for less than 10 seconds, the top of (what I now understand was) the air outtake popped off, along with the underlying air filter. I put the top back on but removed what was presumably a shipping cap and things seemed to work better except the air filter had popped out and I didn't see it. Not only was the air coming out smelly, the pump was overly loud.I saw the filter, put it back in, and it is now reasonably quiet and nowhere near as smelly.But now the inside of the oil indicator is covered with some kind of white particulate or bubbles making it unreadable. I am hoping that just letting the pump sit unused for a few hours will clear that up.I also had to figure out the valves on the piping to actually get a vacuum in the chamber. This was done more by "This must be so you can" and "there must be a way to" than finding useful information in the documentation.Good documentation written once prevents a lot of subsequent labor costs with customer service interaction. Companies should now that by now.If customer service is slow or cumbersome, buyers will be unhappy with the product, even if the product itself is not expensive and (eventually) works perfectly.I have not had enough run-time on it to even know if it works perfectly, as I am sitting here waiting to see if the oil level indicator ever becomes useful.

Well I bought this to degass resin. And I pulled it out of the box two simple connections and tested the pot to make sure it would seal to get a good vacuum and I've had it sitting for about 10 minutes and it hasn't lost its seal pumps quiet so far so good. If I have problems down the road I will update but as far as I can see right now it's a good value for the money and I don't know why but mine actually came with enough vacuum pump oil to fill it. I'm not saying every one of them does but at least mine did

All good

Ça fait bien le vide, la cuve descend à -0,95 bar. Dans mon cas, je m'en sers pour faire des collages sous vide, je raccorde la cuve à une poche dans laquelle il y a les éléments à coller et la cuve sert d'accumulateur. J'ai besoin de -0,5 à -0,7 bar donc ça convient parfaitement. L'étanchéité est tres bonne, la pression ne bouge pas même au bout de plusieurs heures

usata per degassare la resina, raggiunge la massima depressione in qualche minuto e la resina si sgasa molto bene

NO ME A FUNCIONADO PARA LO QUE LO COMPRE

very thick glass lid, good vacuum pump, easy to mount accessories. Resin impregnation process works very well.
