Artibear 3.5 Inch 168 CFM Inline Duct Ventilation Fan with 2 Speed Controller, Air Vent Blower for Hydroponic Grow Tent, Greenhouse, Workshop, Attics, Basement, Kitchens, Black

a really generic fan for duct inflow. 3.5 inch so airflow is not as strong as you might think but is workable for generic use case.

Larger than my 168cfm unit but quieter. 2 speeds. Cord included. Great for horticulture or a dryer vent. Odd sizing mitigated with a spacer. This would work well in a horticulture tent with an LED panel. It's not strong enough for an HID but you could also use it to input air along with a stronger output unit. Not loud, not obtrusive, easy to mount and easy to use.

One thing I love about this fan is that there's very little vibration. Also, there's rubber feet and they have mounting holes too if you wanted to screw it down or mount it on a wall. I expected it to be a bit noisy, but it's not at all - especially once you put a 4" hose on it, it's super quiet.I've had some of those other big name brands and they were louder and one of them didn't last long at all (one 4 month period). So for half the money, you get a better fan that likely will last as long or longer.This fan moves A LOT of air. It's plenty powerful to exhaust air from a large volume, maybe about 3 minuets for a 4x4.

I have a big sized grow tent in the garage to start my seeds and with heat mats and being enclosed, humidity gets overwhelming. This fan helped me vent and circulate air. Its easy to setup on a shelf inside with the zip ties and can plug it on the same multiplug as my heat pads.

We desperately needed a fan for our new DIY button mushroom growing tent. This fan is simple to mount, operate, and it doesn't generate too much noise to disturb our pets who share the same space. For the price point, I wasn't expecting anything in terms of bells and whistles, and it doesn't disappoint. We have it plugged into a Smart Power Strip to take advantage of automated routines. The low speed works for the time being, but our small tent could benefit from an even lower powered fan. If all goes according to plan, we hope to get a bigger tent in the coming year or so, then maybe this fan's output will be more ideal.

My wife works with stained glass as a hobby. Having worked in industry for umpteen years, I know that soldering produces some not so great fumes so I wanted to make a ventilation system for her. Nothing very complicated at all, a couple pieces of dryer duct and this in between. One end of the duct goes right up against the screen in the window and the other sits on her work bench with a 3 sided shape to collect the fumes. It’s not the quietest, but it definitely moves a good amount of air. For the price point, this was a very cheap solution to our situation.

This is a good light-duty fan. It's all plastic, so I'm not expecting this to last for decades. But, it seems well-built nonetheless. Plus, being plastic, there's nothing to rust. There's very little vibration and there's nothing rattling around. Also, I like that this fan is ETL certified, so at least there's some assurance of safety.The fan is surprisingly quiet. Using the entirely unscientific app on my phone, on low, this fan measured 57 dB at 1 foot and 53 dB at ten feet. On high, this increased to 64 dB at 1 foot and 54 dB at ten feet. Using some rubber feet, like those used for chairs, can help reduce the noise slightly.
