È un prodotto di alta qualità, lo utilizzo per VRV per canalizzati o per pompe di calore importanti. Ma ho dovuto fare una modifica mettere due valvole di non ritorno elettriche sull’uscita così evitando, che l’olio della pompa venga aspirato rimanga in vuoto.

Die Pumpe funktioniert gut und hat ordentlich Leistung. Der aller größte Nachteil ist, dass die Pumpe bei längerem Betrieb warm wird und das Öl zu nebeln beginnt. Das ist nicht so Gesund wenn man einen dichten Ölnebel in der Werkstatt hat. Es ist ein Filter verbaut der aber nicht viel bringt. Ich würde unbedingt eine Abluft nach dem Ölfilter nach draussen empfehlen

I like that it has the adapter for multiple hoses but the oil bottle was empty and it doesn’t work as efficiently as an average 5 cfm pump, but it works. If you’re not a pro that needs it on the regular I’d recommend it, but if you need a pump all the time because you’re an HVAC service guy and you need it to to be efficient. You might want to look for a little bit better quality.

Pompe qui semble solide et fonctionnelle au premier abords .. Mais après quelques utilisations perte énorme de tirage .. Problème de confection ? Qualité des palette à revoir je pense

Pump is beautiful but useless with 1/4 imperial inlet which is for R12 refrigerant. Need 3/8 imperial inlet to service R134a. Should have included one in box. Probably have to return for refund.

bonjour nous sommes tres decu de se produits ne fonctionne pas bien tres bruyant les techniciens ne laime pas

I received a vacuum pump from VEVOR on Thursday, March 19, which I needed that weekend to complete a manufacturing job. The unit arrived defective and missing the oil sight glass, which appears to have been knocked into the reservoir during shipping. As a result, the pump cannot be filled with oil or used. I contacted support immediately and was told the technical team would follow up within 1–2 business days. It is now Wednesday, March 25, and I have received no response. I have contacted support four times and each time received the same scripted reply: “we will contact you within 48 hours.” More than five days later, there has been no follow-up, no resolution, and no accountability. This failure has directly delayed a paying customer job and caused measurable business impact. At this point, I am requesting an immediate overnight replacement. If this is not resolved promptly, I will be pursuing a chargeback and documenting this experience across review platforms and business channels. If you depend on your equipment for real work—not hobby use—be aware of the risk.

It stopped working during the first use. It is so hard to return and get the refund
