Orion Motor Tech1.5 Gal Vacuum Chamber with Pump Kit, 3.5 cfm Vacuum Pump and Chamber Kit w Tempered Glass Lid 5 ft Hose, Vacuum Degassing Chamber Kit for Stabilizing Wood Degassing Silicone Resin

Putting it together was easier to figure out than expected but the operation instructions seemed a little confusing at first but I eventually figured it out But it never reached -30 like it said that it should and for some reason it started smoking and had a somewhat concerning rattling. I expected the vibration of course but there was also a rattle along with it. So I’m hoping that doesn’t mean that it’s not going to last long. I’m hoping the smoke was just oil burning off from getting spilling somewhere when it was filled, I was careful but there was also oil all over the pump when i opened the box so idk. I did google the company And tried to email them my concerns so hopefully they will reach back out. Other than that once it did start to work it worked great. Got up to -25 or so pretty quick and was popping bubbles almost immediately and didn’t take long at all for the resin to degass. I’ve only used it the one time tho so we’ll see about the smoking and stuff next time* update so the company reached out and apparently the smoking is normal, but I did drain the oil to the halfway mark and cleaned the area and it didn’t do that anymore and even tho it didn’t quite reach -30 on the gauge it still did an amazing job at removing bubbles within just 5 minutes so yeah I would definitely recommend this vacuum chamber

Easy enough to follow the directions for assembly, and once I fired it up it pulls just shy of 1 bar which was enough to get the bubbles out of my resin.When I removed it from the box there was some oil on the outside of the pump, which was simple to clean off. I also purchased pump oil with this so I drained what was left of the shipping oil and filled it to the line. First time I started it I had a little oil come up through the top but nothing a quick dab of a paper towel didn’t handle.Overall it’s easy to use, the value is great considering it is an inexpensive option, and it feels solid.

Pump ran once and pulled a vacuum. Second time I turned it on, it didn’t run. The fan tried to spin but wouldn’t. Troubleshooting revealed an intermittent fault with the wiring and a bad motor starting capacitor. There is not a lot of room in the control/wiring enclosure attached to the top of the motor and it looks like the component leads were damaged when it was assembled.

Overall, a great product and would purchase again. That being said there are some critics. First are minor and did not affect lost star. The instructions say to take to "30" of vacuum". The system would not take to that level, maxing out at ~23". The system has no leaks (when vacuum valve closed and pump turned off the system held at 23" for 2 hours, and the cactus juice bubbled the whole time. I suspect the issue is the gage is not calibrated or just inherently inaccurate. In the end as long as the system pulls a vacuum sufficient for the intended purpose, success. I took a star off for two reasons. First, the instructions are horrible. For no additional cost, pictures of each process could easily be added, as well as more clear instructions. An example is where to wrap the Teflon tape (provided). The second reason is the hose clamps suck. Turning them closed with any screw driver caused them both to strip. The reason is the screw follow through hole on the screw cage was not completely clear. A 5mm socket wrench allowed me to torque it enough to break through to the other side. One of them the hex head was poorly milled with a gob of metal keeping the socket from fitting. Bottom line, I recommend working the hose clamp before attaching it. Don't be surprised if you have to purchase a hose clamp. Another thing that spending a couple cents more on a little bit better hose clamp would be great.Anyway, assembly took about 15 minutes (most of that time spent jacking with the rinkydink hose clamps). For a budget vacuum tank it works great.

As others have stated, the instructions aren't the best (the images are tiny and unclear). There is a QR to grab and I did that and also watched the video here after pouring the oil into the top cup instead of removing the cup as the video shows. Even so, there was only enough oil for the 2.0L machine to fill it just over half way (bottle is 220mL where the device says it requires 225mL, so I'm sure not all of it has yet settled from pouring it into the outlet cup - there is a plastic valve that can be removed to allow the oil to go ahead and drain into the reservoir).I got full pressure my first few tries - so if others aren't, then you need to check your hoses and seals - don't OVER tighten them either as that is just as bad as under tightening.The larger pump is more quiet than my single stage I used for my airbrush, so I was pretty impressed with that!Being new to Vacuum Chambers (or Degassing as the kids call it today), I only wish the top had more of a lip to assist with centering (more as a safety precaution for us Newbies!)Oh, and hey!? Can there be a clearer image of how far down we need to cut the nipple off of the pressure gauge seal prior to use!? I made mine flush.Great product overall!!! Wish they had a direct link to more oil - anything else I look up looks yellow.READ THE WARNING ON THE LABEL OF THE KETTLE - IT TELLS YOU THAT YOU CANNOT USE IT FOR CERTAIN ITEMS; USER ERROR CAUSES THE RUBBER SEAL TO FAIL AFTER TWO USES!

Everything is great, but the quality of construction of the 2 gallon pot is embarrassing. See the attached photo. There's a divot on the rim which prevents a vacuum from forming. If I push down on this one spot, then it works, but it was frustrating to figure this out. Thanks for another reviewer who pointed this out. I was on the verge of returning it. My advice is to buy the pump alone and get a pot from elsewhere. The rim diameter needs to be about 10 inches.
