PB Motor Tech BMTPB Motor Tech 3 Gallon Vacuum Chamber Kit with 4.5CFM Vacuum Pump, Tempered Glass Lid Vacuum Chamber and 38 Micron Vacuum Pump Kit, No Oil Included, Perfect for Wood Stabilization

Muy buena calidad.

The media could not be loaded.  This is my 2nd Vacuum Pump. I'm not an expert. I'm using it to stabilize soft stones like chrysocolla with Cactus Juice resin. You MUST use a tempered GLASS lid with Cactus juice or it will cause a million hairline fractures in a plastic lid. Lesson learned. This unit has a sturdy glass lid with a very nice seal on both the lid and the chamber. It comes with more than enough tools to assemble and they even threw in a pair of gloves and plumbers tape. My only complaint is the directions are pretty useless so be sure to watch some YouTube videos on using Vacuum chambers to you have the concept before trying it. What is missing from the directions- I used my best judgement and took pictures of how I set it up. The main gauge is screwed into the lid hole using this configuration: metal washer, plastic o-ring, GLASS LID, plastic o-ring, metal washer, nut. Make it tight but not too tight. If you can't get a Vacuum you can always go back and tighten it more. Vacuum oil is NOT included (it usually isn't) so order that when you order a chamber to avoid disappointment. Use a funnel so you don't make a huge mess and don't be in a rush or you will likely overfill and make a huge mess. I used the included plumbers tape when attaching the hose to the pump. The directions did not say anything about how to do this so again, I just used my judgement and you can see what I did from the images. Also, No Karen, I'm not using this in my kitchen....its just where I set it up to make sure it was working before lugging it to the workshop. I think the motor is a bit loud and makes some weird noises but it did pull a solid Vacuum and that's all I need it to do. I'm pretty happy with it and would recommend it.

So far I'm about 1 month into using this Vacuum chamber, and so far it was been perfect for my needs. I'd say I degassed about 10 pints of silicone so far without any issues. The pump itself isn't loud for the time it takes to reach max pressure. Vacuum holds for after the pump is shut off. I definitely would recommend this to anyone starting out.

Worked well degassing 64oz resin. Held vacuum with no leak down.

The pump burned out our socket after the second use. The pump generated tons of oil vapors and gets extremely hot in 30 seconds. After second use doesn't work at all burning any extention cable. Low quality product. More over that you need to pay for the return of 11kg machine by yourself!! That is fully unacceptable work from Amazon and from this seller.
