Customer Reviews for VEVOR 3 CFM 1/4HP Single Stage Vacuum Pump,3 Gallon(13 Liter) Vacuum Chamber Kit, HVAC A/C Refrigeration Kit

Works fine, installation is very easy. I use it to remove air bubbles from my investment for lost wax casting

De vacuumpomp super snel ontvangen, sneller dan in eerste instantie aangegeven. Erg makkelijk in elkaar te zetten. De pomp maakt heel weinig geluid en is heel simpel in gebruik. Ben er erg blij met, helpt goed om de kleine lucht belletjes uit epoxy te krijgen. Zou deze vacuumpomp zeker aanraden!

Bought this 2.5 cfm vacuum pump for doing lay up work on a RC airplane fuselage. The pump works as expected however the oil that was provided with the pump misted and smoked severely. After two or three uses the oil level was low enough to effect performance. I ordered vacuum pump from HD but it was out of stock, not wanting to wait I had a Bottle of NAPA hydraulic jack oil hand, seems to be 10 weight, gave it a try, no smoke or mist, the pump does leak a little oil out of exhaust but it is not big deal, overall I like it. The low quality is based solely on the oil supplied.

Vacuumpomp werkt prima bij het ontluchten van de epoxy Wel jammer dat er nagenoeg geen beschrijving bij zit en ik daarom ook niet weet met welke olie ik straks verder aan moet vullen.

Au venit fara șuruburi de prindere și fără protectia de cauciuc

Had to give it a good clean with iso, had black smear marks all over it. Does it what it's supposed to altho be nice if they had a built in rack system

Günstiges Modell. Erzeugt ein ausreichendes Vacuum für meine Zwecke. Benutzt um das ausgasen von Trägerstoff aus einer zähflüssigen Lösung zu ermöglichen.

User manual is very limited, there are some things to guess when preparing the device before first use. Good device for the Price! The pump is limited in vaccum capability: I was targeting 50mbar but I can get only down to 60-80 mbar.

This Vacuum works as it should. Sometimes the suction of the lid doesn’t quite lineup with the container as the rubber around the top of container is not very wide. But once you mess around to get it in the right spot it works great. If you find it’s not suctioning, just push down on the lid while it’s running at the start to help it Squish against rubber and it works fine from there. When you see the dial starts to move, you can let go of the lid. If you find it’s not working, you need to just fiddle around with the rubber seal on the container. I use it to vacuum RTV moulds for lost wax Jewellery.

Solid package, easy to use. Would love for the pot to be a bit thicker steel. The pump is surprisingly quiet and really quick. Actual vacuum that it can reach is 0.02 bar or 2000 Pa, which is good at this price point. Overall a good purchase and very good value for the money.
