VIVOSUN Z6 6 Inch Inline Duct Fan, 440 CFM Ventilation Fan with Variable Speed Controller for Grow Tent, Indoor Garden Ventilation, Black

I abuse the hell out of these things with gross spore laden humid air and they'll cake up with organic material and I just spray out the inside of the fan until its mostly clean and it just keeps running. I'm sure it'll eventually burn out but they are also pretty reasonably priced so for my purposes they work great.

I recently added the VIVOSUN 6 Inch Inline Duct Fan to my fiber laser setup, and it has made a noticeable difference in my ventilation system. With an impressive airflow of 440 CFM, this fan effectively keeps the air circulating, ensuring that any fumes or dust generated during operation are efficiently removed from my workspace.The adjustable speed controller is a fantastic feature, allowing me to set the fan to the perfect airflow level for my needs. Plus, the fan operates quietly at just 50 dB, which is a huge improvement over my previous setup. I can focus on my projects without being distracted by loud fan noise.Installation was a breeze thanks to the included mounting bracket, making it easy to hang and position the fan exactly where I needed it. Overall, I’m thrilled with this fan—it’s performed exactly as expected and has greatly enhanced my fiber laser experience!

Fan is very powerful, I underestimated it due to a previous purchase of an AC Infinity 8" duct fan.Unfortunately the speed controller probably only goes down to about 500CFM on the lowest setting. I wish I could set the fan speed much lower.

Fantastic unit. I'm adapted to a need for which it wasn't intended. I purchased many Vivosun products and the quality and the value are wonderful. The customer service is also tremendous!

For those that have a larger home and are having issues getting the room furthest from the air handler to get remotely cool. This is your best option. My home is roughly 3500sq ft home and the office room is typically too hot for comfort. I've tried floor fans, swamp coolers, etc., ran this online 6" to boost air and my goodness wish I would have done this sooner. The room was not only no longer hot but legit cold. Like one of the colder rooms in the house. Now I'll just need to find a solution for turning the speed from Low/Medium/High remotely.

The lowest setting will suck all four of my grow tents in and make those high cfm kits shine immediately. I went with something larger than I needed but was using an older system that was more my size before. Once that system was lacking I swapped in and holy crap its got some beef to it. No issues running now a few months so lets see how long it lasts.

Evacuating fumes in the room. Works well but noisy.The speed dial is not good. It will go full blast and as you tun it further, instead of speeding up as you would expect, it will actually go slower.Motor is not very balanced. Low RPM will shake the motor.Cable from the outlet to the speed dial is very very short, almost not usable at all.Who ever designed this, need to stop using drugs.

Been running a full year, nonstop, at about medium speed, zero problems. I have done no maintenance. It moves a lot of air. It's kind of loud, but I can't compare loudness to other fans of the same size. When it was in my living room it was too loud. It's in my bedroom now not far from my bed and that doesn't bother me.I am mining in a grow tent in a small 1br apartment and this ventilation solution has allowed me to max out my apartment electrical grid and keep quite an oversized (for my living situation) mining operation going. I have a smaller intake fan by the same brand, a different model, and with the two fans I circulate the outside air through my tent (both intake and exhaust tubes hang out the window), so that it does not affect the air pressure in my apartment.It was really drafty when I was either sucking air in, or blowing it out. I thought I was getting the Korean Fan Death, my mouth would be soooooooo dried out every morning because my bedroom had like low air pressure. So keep in mind if you are exhausting hot air outdoors, that creates an air pressure gradient with other impacts.I built an audio dampening box out of foam and wood to enclose the tent with the fan in it, and it helped, but was only maybe necessary. Hope this helps!
