VIVOHOME 4 Inch Inline Duct Fan

Works great. Its been on since I purchased it. Pushes a good amount of air. Use for a small tent. I would recommend it for the right application.

Plenty of power

I use this to clear the fumes produced by laser cutting wood. This fan has more than enough power to pull the fumes outside my home and since replacing a smaller fan, the dust and smell are almost gone now.

Not bad for price but not really that powerful.

For a 4inch fan works pretty good. However if you attach a scrub filter to it you will notice a dramatic decrease in airflow almost to a subtle breeze if that. An if you remove the filter be sure to use less than 3ft of hose and to keep it perfectly straight as possible otherwise again you will barely notice any breeze at all. Now for last attempt I just mounted fan to wall with port directly inside sleeve to tent with no filter and no additional hose. Then I noticed some decent air flow from it. But for the price it's at least triple the air flow of the all silver 4inch inline fans that are like 18-24 bucks.

NO JOKE WORKS FOR 2X 4 Foot Tent's BOTH GROWING HUGE

NO JOKE WORKS FOR 2X 4 Foot Tent's BOTH GROWING HUGE with flowering buds! I split the two vents with a converter piece and it worked!!!

It great

The price is right and in my 24×36×80 grow tent the fan works great. The fan is more powerful then you think. Mount fan and filter outside of tent to get maximum suction. I had too buy a 2nd fan for my 2nd tent, and for my 3rd tent I will buy another one

Thumbs up

Nice and quiet not a very strong fan but worked great for what I needed it for.
