VEVOR 1.5 Gallon Vacuum Chamber and 3.5 CFM Pump Kit, Stainless Steel Chamber, Single Stage Vacuum Pump Degassing Chamber Kit, with Acrylic Lid, Oil, 4.92 ft Hose, for Degassing Resin Silicone Epoxies

Works great, held full vacuum for over 2 days. Great quality, solid price point. The gauge is a little odd, you'll have to keep it upright when transporting or it'll leak from the plug that you're instructed to cut. For the price/performance, it's an allowable quirk to me. I used it to dry a stack of repurposed dessicant bags that I use to keep my 3d printing filament dry. I didn't feel comfortable baking clay of unknown origin in my oven at 245°F for 16 hours, I use vacuum to dry vehicle AC systems so I thought I'd try this. It boiled the moisture out of 12 500g bags in less than 10 minutes. I was skeptical that it worked so I vented and pulled vacuum again and this time the vacuum dropped to 30 quickly and just like an empty chamber would, as opposed to the slow, gradual drop over ~7 minutes like the first run. Duplicated on the second batch. Moisture readings when dried bags are put to use validated the result. My PLA and PETG live around 11-16% RH. My idea worked perfectly and I highly recommend it.

This is an excellent product. The chamber held this level of vacuum for 30 minutes. I am pleased with this chamber.

The Vevor 5g with Glass lid has been doing a great job for me. I use it to remove air from Resin prior to pouring. The lid seals well with just a little pressure and the pump draws a nice vacuum. So far it has been performing really well and the added silicone mat for the bottom of the pot is a nice addition. Assembly was very easy thoughI have experience with these pumps so if you are not familiar you may wish to look at some videos.

I would have loved to give Vevor 5 stars for this product, but the item they sent was not the item that was described, and they were not able to supply me with the correct parts in a timely manner. The items that are described include a preassembled vacuum hose with SAE style rubber sealed connectors and a ¾” tempered glass lid with a special rubber gasket capable of maintaining a vacuum to less than 5% leakage over 12 hours. What I got instead of the preassembled vacuum hose was a clear, wire reinforced hose with barbed ends and hose clamps. What I got instead of a special gasket capable of maintaining a vacuum was two square O-rings that not only wouldn’t allow me to reach a full vacuum, but bled off 75% of the vacuum within 10 seconds of shutting off the pump. To fix the hose problem, I ended up buying a preassembled 3/8” Refrigerant Evacuation hose with appropriate fittings to hook it into the gauge assembly. (I did have to unscrew and remove the Shrader valve from the hose.) To fix the seal around the gauge set, I put a bead of silicone seal on the upper washer, added one of the silicone O-rings and snugged down the gauge set onto the lid. I wiped off the excess silicone seal on top of the lid and let it sit until the silicone was cured. I then removed the lower nut, added the second silicone O-ring and filled the remaining space between the gauge set pipe and the glass where it comes through the lid with silicone seal. I made sure it was full of silicone seal so that when I mounted the lower washer and snugged down the nut, silicone oozed out under the edges of washer. I then cleaned off the excess silicone and let that cure. I now have a vacuum chamber that not only achieves the maximum vacuum for my altitude, but it holds that vacuum for 24+ hours with NO discernable loss. The product is a good product, and I am happy with it. But it sure would have been a lot easier, a lot more efficient and a lot less costly for EVERYONE concerned if Vevor had just shipped the right parts with the assembly in the first place.

Working good

Update: One of the handles has now come off of the pot with the only weight being the lid on the empty pot. This thing is junk. Arrived with a defective gauge that read -3Hg when no vacuum pulled and pegged well past -30Hg when pulling a vacuum. Vevor support was a pain to deal with. Contacted support here and they told me to contact Vevor support. Then contacted Vevor support and dealt with AI but then was connected to a person. Yay right? Not so fast. After an initial message from the person saying they'll be with me shortly, had to wait over 30 minutes asking if anyone was still there for them to finally get back to me and soon after tell me that someone else will contact me within 2 days. On the second day, I'm contacted and told they don't have the part (replacement gauge) in the warehouse and told me to contact Amazon support to return the product. This is far to drawn out a process for a part that only costs a few dollars. I'm just going to buy another gauge to avoid the further hassle and be done buying Vevor products.

Very high quality kit for the money, especially on sale. I was worried about the amount of noise the pump would make but it turned out to be quieter than a vacuum cleaner. Had no problems with sealing and was very easy to use.

Works great !!! Thanks

⭐⭐⭐⭐⭐ Top Vakuumkammer – massive Qualität, einwandfreie Funktion Die Vakuumkammer macht genau das, was sie soll. Die 19 Liter Volumen haben für meine Anwendung komplett ausgereicht. Ich habe damit einen Epoxidharz-Tisch gegossen – hat einwandfrei funktioniert. Die Qualität ist wirklich top: sehr massive Ausführung, die Scheibe ist ultra dick und macht einen extrem stabilen Eindruck. Alles sauber verarbeitet, nichts wackelt. Auch die Dichtung funktioniert super und hält das Vakuum zuverlässig. Klare Kaufempfehlung 👍

Davvero soddisfatto! Degasa perfettamente resine e siliconi. Finalmente epossidiche trasparenti perfettamente prive di bolle! Si nota drasticamente la qualità delle mie creazioni. Sono rimasto stupito da quanto ossigeno può esserci intrappolato. Lo sto usando da qualche giorno di continuo. Funziona sempre egregiamente. Mi ha sorpreso molto il motorino di aspirazione, molto silenzioso. Tutto è compreso per darti modo di usarlo subito! In dotazione una chiavetta per stringere i bulloni, cacciavite, guarnizioni, fascette e olio per il motorino. Tutto! L'ho montato e usato subito! Le istruzioni sono in inglese ma il montaggio è stato semplice anche per uno non troppo esperto come me. Direi assolutamente 130€ investiti bene! È un prodotto di qualità, si vede! Cura nell'imballaggio e spedizione arrivata un giorno in anticipo. Non lascio molte recensioni, ma questa se la meritano proprio! Ottimo lavoro! Sono molto felice

Top produit.

Work well

I needed a vacuum tank because I pour a lot of epoxy, this unit came and was easy to set up and have used it for a while with no issues, I would recommend it.
