Reseñas de clientes para VEVOR Ventilador de conducto en línea de 4 pulgadas y 200 CFM con controlador de velocidad variable, silencioso, con motor de CA, para refrigeración, carpas de cultivo e hidroponía.

It does the job but it also allows dust/smoke to blast out the sides of the fan, not very quiet unless on lowest setting, vibrates like crazy nothing that I can tell of is imbalancing the fan I assume it's in the motor

Not satisfied with product , not enough pressure , I installed in line of kitchen range hood to clear out fumes , didn’t get any help even kitchen hood fan has more pressure this is creating obstruction to flow of air so I take out , I want to return it Ple let me know process how to return it Thanks

My personal experience with this fan is has 3 speed modes and the fan did not produce anymore air flow than i was already having with the vevor diesel heater. I was using the duct fan to produce more air flow and the fan did not improve / add to air flow. The fan is extremely weak and not ideal. Not even sure what a person would use this for if it doesn't put out per say.. Im feeling unsatisfied and wanted to return it and the process is difficult and still hasn't been rectified since January 2025 and its October 2025. I would habe wanted to use the money from the fan to buy something else in the vevor catalogue. The help from vevor after they have your money is unacceptable as its not dealt with in a prompt manner..

This fan seem fairly well built but don't have the air flow i was expecting, they're ok considering the price point

The fan works well, good speed control, reasonable noise (most of the noise in my case comes from the air duct), and easy settings. However, the product page used to state it was suitable for all temperatures, which is misleading. The manual, information that isn’t obvious until after purchase, shows a strict high-temperature limit. This makes it unsuitable for HVAC heating applications in winter. If Vevor offered a blank plug to replace the motor for off-season or heating use, it would be far more versatile. Works fine for cooling or ventilation, but not for winter heating ducts.

I picked up one of these fans due to its high airflow and rated static pressure rating of 300 Pascal's. The fan, as delivered, is only able to achieve 100 Pascal's of peak pressure, at which point the airflow drops by a factor of 10. I intended to use this with a filter as a low-noise fume extractor; but due to the very poor pressure handling (which I shouldn't be surprised at with a 68W power rating!) it's completely unsuitable for this application. In its intended use of home or small-space ventilation, with sufficient make-up air to maintain a sub-100 Pascal pressure differential: it does absolutely meet and exceed it's 800CFM rating. Had I used is strictly as designed: it's a pretty decent fan! For my purpose, the fan is rated incorrectly and this should be updated.

There is a constant hum that sounds like a stalled electric motor, but it does not change pitch with speed. I don't know if that's normal or not. It uses 70w/1.5A on high. Seems quiet otherwise.

Lüfter wird als leise beworben. Leider ist der Lüfter so laut das er selbst bei niedriger Drehzahl nicht im Haus betrieben werden kann.

⚠️ À fuir – pratiques proches de l’escroquerie ⚠️ J’ai commandé un modèle affiché à 348 m³/h pour 64,90 €. J’ai reçu un produit inférieur, le GX-04-100, limité à 220 m³/h et vendu bien moins cher. Malgré les preuves évidentes (mail de confirmation, références, photos), le service client nie l’erreur et affirme que le produit reçu serait le bon. C’est tout simplement malhonnête. Envoyer un modèle moins performant et moins cher, puis refuser d’assumer, relève de pratiques trompeuses. En regardant les avis, je ne suis clairement pas un cas isolé : problèmes de retours, mauvaise foi, refus de reconnaître leurs erreurs. Si vous ne voulez pas perdre votre temps, votre argent et devoir vous battre pour faire valoir vos droits, passez votre chemin. Entreprise non fiable, méthodes douteuses, expérience client déplorable.

Circuit imprimé grillé au bout d'un mois. SAV long à répondre Il a fallut que ce soit moi qui démonte d'après leur instructions pour le diagnostique. Produit sous garanti aucun échange possible mais envoi du circuit imprimé avec délai de livraison estimé est de 10 à 15 jours. A moi de me débrouiller pour changer la carte avec des connectiques scellées à la colle !!! Je n'ai pas le choix si je veux un jour réutiliser ce matériel. Dommage dernière commande chez VEVOR
