BACOENG 3 Gallon Vacuum Chamber with 3.6 CFM 1 Stage Vacuum Pump, Degassing Chamber Kit with Acrylic Lid for Resin, Not for Stabilizating Wood or Making Fish Lures

I purchased this for degassing silicone and it works great! Follow the instructions because it sounds like you can break the pump if not used properly. I used this multiple times a day for about two years without issues. The only reason I'm retiring it is because I needed a larger chamber. This ended up being a great starter unit that I could depend on for daily repeated use and I highly recommend it.

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.

My first vacuum chamber, and one I bought on recommendation from a friend. The first pump I received was broken in a strange way- it functioned, but leaked oil all over. Thankfully, it was swapped out when I reached out to support, no issues. The new one works perfectly, however I don't have too much faith in the valve stems, which are somewhat wiggly when I go to open or close them. I've not had any issues of leakage, but I am warning you to be gentle with them. Decent little starter! Also, to resin newbies- if you're trying to remove bubbles, a pressure pot is better than a vacuum chamber, unless your pour is something that's pretty flat. So, dicemakers should opt to look into pressure, instead, and follow every direction on the pressure pot- they are a bit more dangerous than a vacuum chamber!

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.

This is the third unit I have ordered from Amazon and all three had to be returned. The first one was perfect out of the box, but would not pull a vacuum unless I pressed down on the lid with both arms extremely hard. I tried going through customer service, but after several days with no response I just made the exchange through Amazon. The company rep did finally get back to me and said they did not have any 3 gallons in stock, but offered a different type of chamber that didn’t fit my needs. When the Amazon replacement arrived, it was clearly a used unit. Oil already in the reservoir, residue build up on the fittings, and other obvious signs of previous use. Sent that one back for a refund. Company rep told me to return it for refund and order a new one, so I did. Third unit arrived and the valve housing fitting was cracked right out of the box!! The bottle of oil was sealed, but dirty like it had been on the floor of a jiffy lube all day. It appears to me that they do not have stock in the US right now and are either selling their scratch & dent units (B-stock) or are taking the working pieces of warranty returns and piecing together the kits to sell as new units. If that’s not the case, then the quality of this product is just not what everyone is raving about in previous reviews.

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

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.

No se si haya mejores marcas de estas bombas, yo la he visto en videos y funciona bien para desgasificar el caucho de silicón, en lo personal siento que debería resistir mas vacío, trabajé al vacío máximo recomendado y aún así siento que tarda demasiado en desgasificar. La olla de tres galones se escucha espaciosa pero ya viéndola y en el uso, termina siendo pequeña... no quiero imaginarme la olla de un galón
