Reseñas de clientes para VEVOR Bomba de Vacío 4CFM Bomba de Vacío para Aire Acondicionado de Etapa Única Bomba de Vacio Coche con un Cubo de Vacío de 3 Galones

Chambre, avis, fonctionnel, un peu dure à l’utilisation, qualité des matériaux, plutôt acceptables et le prix est un peu cher

Je viens de déballer et tout fonctionne correctement mais une des vannes est complètement oxydée. Étrange pour du neuf.. pas top..

Ottimo acquisto Spedizione con tracking regolare e veloce ad eccezione di alcune cose che sono uscite rotte dall imballaggio come il filtrino per l aria e il tappo per lo scarico dei fumi

`Just received the pump, assembled it in one minute by hand (no tools or lube, so probably not a perfect seal), read the warnings, and turned it on. The pump is very quiet, beyond what I expected. It pulled the 3gallon chamber to -0.95 bar in about 30-40 seconds, enough to destroy a small balloon I accidentally left in the chamber. :) The pump produces some vapor (it isn't really smoke I think) past -0.5 bar, but from what I read this is normal behavior. It holds the vacuum impressively well. Remarks: 1. The oil in the pump was at min-level, so I had to add most of the extra bottle to get it to almost max. 2. The pressure gauge wasn't entirely filled with glycerin (not sure whether that is a quality issue, but still). 3. There are no 'convenient' handles on my 3gallon chamber, it's just a pot.

matériel semble ok, pas encore utilisé

Ich habe die Vakuumpumpe zum Holz stabilisieren gekauft das funktioniert wunderbar. Leider hat der Plexiglasdeckel nach der zweiten Anwendung schon Risse bekommen .:-(

Erfüllt seinen Zweck. Allerdings hätte ich die Pumpe mit etwas mehr Leistung nehmen sollen.

Setup was fairly easy, it was just not entirely clear where to pour in the oil, as there were two openings at the top. In the end I poured it in the bigger one, which seemed to do the trick. The pump releases quite some white steam when turning on, which seems to not be an issue, but it does fill up the room with smell. The vacuum performance itself is excellent though. The pump draws a deep vacuum, and with the closed lid the pressure is held for several hours. Great setup for silicone mixing and casting!

De vacuümpomp en vacuümkamer worden gebruikt tbv het luchtvrij maken van epoxy. Bij het mengen van de epoxy-componenten A en B krijg je altijd te maken met luchtinslag; deze luchtbellen zijn mbv de vacuümpomp en vacuümkamer goed te verwijderen. Bij het gieten van de epoxy krijg je vervolgens volledig heldere epoxy plaatjes.

Werkt prima denk ik , ik krijg alleen niet de gewenste resultaat .
