BACOENG 6.8 Liter Vacuum Chamber Kit with 3 CFM Single Stage Vacuum Pump, 3 Pin UK Plug

works good easy to use thanks.

This is a simple product to set up - you basically plug the vacuum pump to the vacuum chamber, together with a few other bits like filling the oil (supplied) into the pump. All fittings seem to be sturdy and well made. I liked the see through top as you can observe the bubbles coming out of the resin! It's an expensive purchase but so far it's worked perfectly and I'm glad I've got it for my resin work.

Not normally a review writer, but this Vacuum chamber has impressed me, despite the few negative reviews, it turned up, very well packaged, set up was as easy as filling the compressor with the supplied oil, screwing the hose to the compressor and the chamber lid, plug it in and off you go, pulled a vacuum down to -30inhg and held vacuum to pull the bubbles out of the resin would highly recommend this bit of kit to anyone questioning whether to buy or not.

I looked long and hard when deciding to purchase a vacuum pump and chamber for degassing silicone. The highest quote for a complete system I had was £1000 (a UK company), there were intermediate priced kits too, and then the “BACOENG 19 Liters Vacuum Chamber Kit with 3 CFM Single Stage Vacuum Pump, 3 Pin UK Plug” at £229.99. I chose the BAC kit as (a) it was a lot cheaper and (b) they had the taller chamber in stock that I needed. It is a single stage pump so I knew it would not evacuate the chamber as fast as a more expensive pump.I had concerns from the start having read some poor reviews. Several said how poorly packed the kit was and that the chamber arrived with a dent where the pump had hit it in transit, also that the base of the pump was bent and would not stand level. Bizarrely, after I unpacked my order, that on first appearance seemed well packed with foam, I found the same two faults! The minor dent did not bother me and I took the base off the pump and straightened it. It is now fine.Assembly of the kit is fairly straightforward although the instructions being of Chinese origin are somewhat confusing at times. – What washers to put where, where to fit the filter, that kind of thing. I did add two stainless steel washers against the rubber sealing washers to make for a better seal through the chamber lid.Upon first operation, having put the oil in the pump [Oil is supplied, but only exactly enough to fill to mid-way point], I noticed vapour venting from the oil filler cap. It took a while to realise that this is correct and the evacuated air is “in” the oil and the “exhaust” is combined with the filler plug. After several operations the top of the pump does get a bit oily and if used in a confined space there are some fumes. The oil level does go down and after several evacuations the oil is a little bit cloudy so buy plenty of extra oil at the same time of purchase. It seems vital to change the oil very regularly.The other notable point is that the gauge has a rubber plug on its top. When everything is set up, you are told to vent the gauge by cutting or puncturing this cap to equalise the pressure. I found you can just pull it off with your fingers, and then when you are finished, put it back in. This helps avoid spilling all the glycerine fluid out of the gauge when you accidently turn the lid sideways!The actual operation of the pump and chamber is very good. The pump clearly removes most of the air as silicone froths up and bubbles away when you reach near the maximum on the gauge. I avoid running the pump unnecessarily so when a low vacuum is reached I switch it off and then close the valve. I did a test before vacuuming anything and found that the chamber held vacuum overnight.I am at the point where I need to change the oil. The manual states - running the pump for 30 minutes to warm it up, but doesn’t say whether that is under load or straight to atmosphere. It then says to drain the oil from the drain plug and run the pump without oil for 3 minutes while pouring a small but unspecific amount of oil into the pump inlet – Apparently cleaning out the remnants of old contaminated oil. This procedure seems against logic when the oil is so important to the condition of the pump! I need to check this procedure before doing it.In summary, if you have plenty of money and are going to use it many times, buy a better, faster costly system. If you are only going to use it occasionally and don’t want to spend loads of money then the BAC seems to me as good as any other budget system. Spend wisely on the best premium pump oil and change regularly. Even after each “session” if it is to be put away for a few months before being used again.

The quality of the pump and chamber are excellent. Hose connections are easliy fitted and vacuum is monitored by a guage fixed to the pipework. I have used the equipment many times without fail. My only comment is that the instructions do not explain how the equipment should be connected. There is no oil type recommended so further investigation is need to procure replacement oil.

Good quality kit for the money, the pump is really good and unlike others out there, actually does the job well. Take your time with assembly and ensure all joints are PTFE’d to save messing about later.

Great qualityAlmost silent - i run it under my desk in the study and can easily watch Youtube whilst it is runningdraws a full vacuum very quicklyEssentially, there is no issue, nothing to be concerned about, and it is great for resin workWould purchase again without any hesitation

The machine was easy to unpack, set up and use! More-or-less fool proof! I think it's good value for money, and does its job well. However:I'm writing this complaint here, because I can't figure out how to contact the seller.I bought this chamber and pump a few months ago, and it works like a dream if not being a little loud.However, I noticed something about a month in.That was that my machine appears to leak oil.Initially, I thought I'd imagined it or maybe spilt some during filling, and it, being oil, hadn't dried or evaporated. However, I've noticed, the machine still seems to be leaking oil. Furthermore, I feel as though the sound it makes changes overtime, and today, I could have sworn I saw smoke or some other air being blown from it during use.This product kinda scares me now, haha, and i'm not sure if it's safe to continue use.I also know I probably have no chance of a refund now, which sucks.
