PB Motor Tech 5 Gallon Vacuum Chamber Kit with 4.5 CFM Vacuum Pump, Tempered Glass Lid Vacuum Chamber and 38 Micron Chamber Set, No Oil Included, Perfect for Wood Stabilization

My wife decided to clean up the pantry and put all the dry goods in mason jars. This allowed me to vacuum multiple jars at once. It pulls a much deeper vacuum than the typical vacuum for jars and bags. The pantry looks great and the dry goods are going to last longer. Be aware this requires oil to get this level of vacuum and does release some into the air when in use. Reasonably priced and easy to use if you’re familiar with this area. I have also used it to pull moisture out of 3D Printing filaments and bubbles out of resin epoxy. The vessel seals better than I expected and will hold a 28.5” + vacuum for days. The pump pulls down the vessel quickly.

Works very well. Creates a vacuum quickly and holds as long as you want.

I use this for removing bubble from resin and it works great. My only complaint is it did not come with any oil in it so make sure to get some when you purchase. There a fill gauge on the front of the vacuum pump and it worked a lot better after adding oil.

Workes great. Looks great. Couldn't of asked for more

It aooears to work great . Easy to set up and use . So far , so good !

I bought this for my husband who recently started working with resin. He loves it.

We have a few different sizes and brands of vacuum chambers in our classroom. This one from PB Motor Tech, compared to the others, is a well made quality product. The double seal works well. We've had no issues with the gauges, but over time, they do seem to lose pressure through leakage more than others. They still function well. I do like that the chmber is lighter weight than others.

Great kit for your vacuum chamber needs! Easy to setup pump, did purchase oil separate. The chamber is very large and does not compress when near full vacuum. Highly recommend this kit. Used to show what a vacuum does to marshmallows and the like.
