    • Fantastic value
Size: 4 Inch Basic
I bought this to ventilate a small paint booth I had thrown together while working on restoring some old car parts. This fan is very quiet, smooth, and pushes a lot of air. It's compact yet powerful, and the adjustment allows me to raise the speed when spray painting to get rid of overspray, and slow things down to let the paint off-gas/cure quicker. The fan has held up against a lot of spray paint being sucked right into it and has no issues. It works as I intended, and the included clamps are a bonus. ... show more

    • Powerful little fan
Size: 4 Inch Basic
So far this fan works great. Using it to vent out cat litter smell and so far it is working like a charm. I like the variable speed control, works perfect. Has a hum to it but I wouldn't say it is loud. I have this fan in the laundry room venting the cat litter box. Well, it worked a little to good and was venting warm air from the house. Not the whole house but any room connected to the laundry room. So it does have some power to it. ... show more

    • More powerful than it looks
Size: 6 Inch
Update (1 year later)... One star deduction. The fan power supply died just short of 1 year. The fan started cycling on and off. I replaced the power supply with a 24 volt non-adjustable type and the fan is working great again. In fact, I like the air volume so much I just purchased the same model for my other son's room. The factory power supply runs extremely warm so I'm not expecting it to last. I'll be ready with a 24 volt model when it happens. I have a second floor bedroom used for PC gaming that gets unbelievably hot in the summer. Installing a booster fan in the 6" duct leading to that room mostly solves the problem. I had a 240 cfm all metal duct fan running for about three years that finally died. It was noisy and didn't seem to push as much air as advertised. This Hon&Guan model is a major improvement. Although being 100% plastic, it still easily mounts to the duct using aluminum duct tape. The claimed 345 cfm airflow is no lie. I plugged it in before installation and it rearranged all the papers in my kitchen. Compared to the twice as expensive home center metal duct fan, this one has 100 cfm greater capacity, half the power usage, adjustable speed and lower noise. My son gave me the thumbs up after a day of use. His room stays in the mid-70's (deg F) compared to 87-89 (deg F) without the fan. It is only activated when the furnace blower runs so it is not constantly on. If it lasts a few years I'll be very satisfied. ... show more

    • Great for Fog Machine Setups
Size: 4 Inch Basic
Review Image by Marty S.
This inline booster fan worked great for my fog machine at Halloween! It comes nicely packaged up and protected and sets up in under a minute. I have a custom-built fog-chiller that pushes out a TON of fog. Over the years, I noticed that the fog doesn't make it far enough into my graveyard scene so this year I added this little item. My setup involves a fog machine, a fog chillder, 6 feet of dryer duct hose and this booster duct fan. My fog machine feeds directly into the fog chiller which cools the fog and keeps it lying low to the ground. The dryer duct hose is connected on the opposite (exit) end of the fog chiller where the cooled fog exits. The variable speed booster duct fan is on the other end of the dryer duct hose to draw the chilled fog out and disperse it. The variable speed switch is great for adjusting the speed of the fan to get the right volume of fog to disperse. The only caveat is that the fog residue builds up on the fan blades, which is easily remedied by cleaning them after using it with a fog machine. I highly recommend this item for use with a fog machine. (DISCLAIMER: The diagram provided below was generated with ChatGPT and is for illustrative purposes only of where the booster fan is placed in my fog chiller setup. The drawing is not to scale and is not a proper representation of the size/shape/design of the Booster Duct Fan with Speed Controller.) ... show more

    • Works Good
Size: 4 Inch Basic
Plugged it in and worked no problem. Quality seems pretty good, no crazy vibrations. Not too loud on lower settings but I like that you can adjust it with the dial. Airflow seems adequate.

    • Great airflow-a bit noisy
Size: 6 Inch
First off this moves a nice amount of air. I hooked this up to my voiceover booth so it doesn't turn into a sauna during long voiceover sessions. The only problem is that past about half speed it gets too noisy and bleeds thru to the booth... but half way keeps enough air moving for me., and at this price point I'm not going to complain. The problem I have is that the remote cable with the on/off/speed control is not long enough to run inside the booth but I MacGyvered it by setting it at mid speed and plugging it into a WiFi plug so I can just have Alexa turn it on and off as needed even during a session. ... show more

    • A not so quiet place
Size: 6 Inch
There wouldn’t be a “Quiet Place 2” if Emily Blunt had been using the “quiet fan”. Works great but that thing is loud and I’m a New Yorker so I know a thing or two about noise! Otherwise, sturdy build, nice finish, the controller could use a little upgrade/update but for the price, it’s totally fine. ... show more

    • Good cheap option
Size: 6 Inch
Nice fan, pushes a good amount of air. It had a small hum to it, I tried another fan that was more expensive and it was quieter so I ended up returning this one.
