Inline Fan 4 Inch 190 CFMwith Speed Controller, 4 Inch Carbon Filter and 8 Feet of Ducting, Temperature Humidity Monitor for Grow Tent Ventilation

Great in my 3x3. Does as good of a job as I need. Comes with everything you need to vent. Great budget friendly option for anyone who is okay running things manually. It's very queit when running which is great bonus.

Die 200mm hat ordentlich Power. Perfekt für ein großes Zelt. Starker Unterdruck. Geräusche entstehen halt bei so einem Gerät. Mit dem Gedämmten Schlauch lässt es sich aber gut regulieren.

I really like this kit, for the price, amazing. I seen a review on here that got me interested in this kit. I own a few Vivosun products already and I really like them dispute what some people have been saying about the brand, I haven’t been let down yet. So I was initially looking at 4” lots because well money became a factor but necessity was also present so I decided budget was where I wanted to go for now, maybe upgrade later. Well to my surprise this kit was cheaper then most 4” kits from other brands, so I have it a whirl, worst that could happen I’d have to send it back. It showed up super fast, SUPER FAST. Pretty much next day. The fan itself is very light but solid molded plastic housing makes for a sturdy light addition. The filter super nice, super strong, came with prefilter sock and straps, again impeccable design of quality, beauty and strength. The extension tube, I read some people saying it was paper thin and terrible etc... it’s actually really good quality if you know these tubes from installing say driers and such. If you want though get a hard plastic portable AC tube to replace it but you really don’t need to. The fan if placed inside the grow tent doesn’t emit much sound outside the tent, and outside the room the tent is in it’s not even noticeable at a moderate speed. If placed outside the tent well it’s just obvious you’ll hear more noise from the fan but it’s no louder then a standard tower at a moderate speed, full blast it probably competes with a bathroom exhaust fan for noise which is actually close to nothing at all. All in all well worth the buy I wouldn’t go any other way. Why spend more when you have a great quality option right here.

Super Abluftanlage, der Aktivkohlefilter tut was er soll, kein Geruch mehr in der Wohnung, super für den Innenanbau! Lüfter reicht auch auf halber Stärke aus um Temperatur und Luftfeuchtigkeit im Rahmen zu behalten und den Geruch zu entfernen!

Worked as expected and moved a lot of air in my small tent. The filter does not last very long though maybe a month.
