Customer Reviews for 5 Gallon Vacuum Chamber Silicone Expoxy Degassing With 3CFM 1/4HP Vacuum Pump 84 L/Min

This little vacuum system is perfect for my needs. Small epoxy projects are having much better results now that I can remove the air bubbles before pourings. Easy to set up and use.

Great value, good quality, incredible price. Easy to use, relatively quiet. I am using it to degas epoxy resin and impregnate wood with resin.

I've been using this to degas silicone and it gets the job done, but it's a little slow and could benefit from a stronger vacuum pump. Some tips - - Use a silicone with a pot life of 15 minutes (cure time 45 minutes) or more, otherwise your silicone may gel while pouring after waiting for it to fully degas. - Mix your silicone components in a jug (with a spout) that is at least 8x the height of the mixture in the same jug, or your mixture will rise so high while degassing that it will spill over the edge. - Don't put the jug of liquid silicone directly under the opening in the pot lid. If the mixture is under the opening, air will re-enter the chamber when you open the inlet valve and cause a jet of gas to push itself into the mixture, creating more bubbles. If the container you're using is too big to achieve this, don't open the inlet valve all the way - just let air in slowly so it doesn't smash into the mixture. - after degassing, pour the silicone from 20-30cm above the mould box or positive so that it pours in a thin stream, and any remaining bubbles will pop.

The Vevor 3 Gallon Vacuum Chamber works very well, and is very quiet compared to my wife's resin vacuum chamber. We use it to vacuum seal food jars. The lid is very well made. I wish the lid had an edge under, against pot, you just make sure lid is centered on pot. System is very easy to use, and is at a good price.

Great pump, works great. Just at start up for a couple minutes it has alittle atomized oil coming out the exhaust

This vacuum chamber is perfect to use in sealing not only Mason Jars for food preservation, but also pickle jars, Salsa jars or others with a sealing lid. I just put the closed jar into the chamber, pull a vacuum, and then release. The lid will pull down sealing the contents in an air tight vacuum to help keep my dehydrated foods safe. This saves me money by allowing me to reuse my condiment jars and not throwing them into the land fill.

Excellent quality. Works exactly as advertised. Great videos found for set up and use online since Vevor does not provide a setup/ instruction manual. Just the pump manufacturer manual is included.

Worked great. Quieter than I expected. I have tried this a couple times so far and it works like it’s supposed to. I use it to pull bubbles out of plastisol while making soft plastic lures. Made crystal clear baits! Costs less than other brands and does the same job.

Works well make sure to keep eye on oil level Did smoke a bit when first started but seem to clear up After few times

Easy to use. Fill pump with oil, connect hoses, drop on gasket, turn on. Held a vacuum all night. No regrets with this purchase.
