VIVOSUN 6 Inch 8 Feet Non-insulated Flex Air Aluminum Ducting for Ventilation w/ 2pcs 6 Inch Stainless Steel Clamps

Funciona muy bien

The fan encasement is made from a duct-like material, but it is much stronger and more rigid. The fan has plenty of room inside the ducting should the encasing ever be dented or deform from mishandling or falling.When I received it, it would rumble loudly throughout the ducting; the issue had something to do with the seating of the fan blade, because I took it off and ran it and the motor itself was silent. I removed the fan blade, applied some oil, and pressed in the blade while tightening the nut which holds it on -- the rumble was reduced significantly.Overall, an excellent fan exhaust fan at a solid price. Any workshop, growery, or perhaps a smoking room could benefit from this addition greatly., especially with the addition of a carbon filter.

Es potente, un poco más ruidoso de lo esperado, el control se calienta si lo tienes en máxima velocidad.

I don't care about plastic housings and I'm happy to wire my own switches where relevant, so for me and the applications for which I use fans (in this case, cooling inside my truck/paired with optional swamp cooler water flow), this is awesome bang for my buck. It's a bit loud but I don't care, that's to be expected when going for something with high airflow.I do wish I'd considered getting a couple of different sizes because this is actually more powerful than I need for its current use, but that's fine, sooner or later I'll move it and the attached swamp cooler setup I built to a different larger space and build a new smaller one for my truck. I'd much rather overengineer something than have it be insufficient (like my first pitiful swamp cooler attempt with computer case fans -- fun starter project to learn about wiring in series and wiring a three-prong switch, but totally inadequate for cooling the inside of a Ford Explorer!).So yeah, can't speak to how good this is for actual use in ducts, but as a cheap powerful basic fan for a DIYer doing something fan-related, it's a great buy and I'm thrilled I got it. The only way it could be more perfect would be if it had an on/off switch already integrated into the power cord, but that's not a big deal and of course it's not like it advertised/implied that it would have one. It's exactly what I expected, except more powerful. Everything about it seems solidly made and I anticipate it'll last a very long time. I'll most likely buy from this same manufacturer again in the future when I need fans of other sizes.

Esperamos de mejor calidad, resistente y más potencia de extracción, pero lo califico como bueno!!!
