Customer Reviews for VEVOR 3CFM Vacuum Pump With 2 Gallon Chamber Kit 120w Vacuum Pump Manifold Vacuum Drying Pump Aircon Vacuum Pump

Good product, easy to use. Only the manual wasn't very clear, and had to fiddle a bit figure how to install the valve on to the Acrylic cover. Overall, performance very well, the pressure dropped to -30inHg very quickly.

For all resin workers, I have found this option really useful for degassing the resin (once mixed). I mix my resin, then degass in the vacuum chamber (this is the part where you have to pay attention!, a balancing act between too much vacuum where the resin literally boils up and out of your container and not enough. It doesn't take long to figure it out).It doesn't remove all bubbles but seriously reduces the bubble count if doing deep fills.(If you don't want bubbles at all, you need to compress to 4 Bar)

I bought this for my dad who uses it for his wood work, where he combines wood with coloured resins.He loves it. The only thing is we wished there was some instructions to go with it. He found out how to use it by watching videos on line. But never quite sure if he is using the Teflon sheet correctly.

Muy buena calidad, la succi_ es suficiente para permitirme hacer mezclas de silicona sin burbujas y hacer buenos moldes, la recomiendo, f_il de usar, f_il de montar y f_il de llevar.

Sehr gutes Produkt f_ das Geld.Man mu? zwar direkt Vakuum?l kaufen und es fehlt bei der Verschraubung oben eine gro?e Beilagscheibe damit es dicht ist, aber das ist zu verschmerzen.Habe es bis -0,9 Bar getestet, h?lt auch den Unterdruck einwandfrei.Keine Verformung im Beh?lter zu bemerken.

Pump working great!Seller very friendly.

Aansluiting manometer op de deksel kan beter. Is wel luchtdicht. Pomp kwam met minimaal olie

Super Pumpe! Sehr leise und das Vakuum ist so stark, dass Epoxyd zu kochen beginnt. Nicht _er 10min. saugen, sonst wird sie zu hei?. Der Druck h?lt aber auch bei abgeschalteter Pumpe konstant.

F_ den Preis gute Ware, Achtung, ?l gleich mitbestellen, sonst l?uft die Pumpe trocken.

TL;DR: Add/replace oil and calibrate the gauge, but otherwise good pump.When I first received the pump and, naturally, tried to boil some water, I was utterly disappointed. It was not reaching vacuum at all, and was getting quite hot.After reading comments to similar pumps here I've tightened all joints the best I could, but it didn't help at all.The oil level was within limits, but closer to the min level. So I decided to add some. And it did the trick, the pump pulled a fairly good vacuum, the water started to boil fairly quickly, and the gauge went below -1 atm.This brings me to the other point. The gauge is not calibrated, so its reading is not accurate. Keep that in mind.Order some oil with the pump, don't expect it to be ready to go. Mine wasn't.
