Review: Deceptive marketing but still love the fan. - Edit: I like this fan way to much to leave the one star review in place. I still stand by my original reasoning but can't help liking and even emphatically recommending this fan based on how well it works and the overall look and feel of the build quality. At the second of 10 speeds the sound from the fan itself is hard to discern although there is a very noticeable woosh from the air itself flowing through the opening of the tube on my desk. Even at this low speed it seems to provide enough ventilation for me. Original review (1 star): Ignore the noise ratings and probably any claims really. It's a fan. It sounds like a fan and moves air like a fan. The whisper soft 29dba or w/e it is supposedly rated for is more like 70+ in reality. Based on how grossly that was misrepresented I can only imagine the airflow and power ratings are likewise no where near reality. That all being said, I really like the fan I received. It's not what was advertised but I pretty much expected that going in so... The noise is pretty loud at mid to high settings but is mostly a loud but soft woosh sound and with the hose attached I doubt it would bother most people. I plan to use it for venting solder fumes and it will likely be plenty powerful at it's lowest settings which is actually almost silent to it's credit, although customer service on their website flatly stated the unit was tested for sound at max speed with hoses off. Can't give it 5 stars because the fan does not live up to the promises in the listing, but it's a pretty good fan none the less, just know what you are getting into. If you need to rely on the specific performance data for any reason I would suggest buying something legit, otherwise if you just need a fan this one's pretty decent.

## Questions & Answers

**Q: What is the length of the speed control cord?**
A: 5ft
It look like an USB-C so maybe you can extend it.
When disconnecting the remote the fan goes full speed, then back to previous setting when you reconnect it.

**Q: How long is the adapter to use with the digital controller?**
A: approx. 10 to 15 ft long

**Q: One user stated that they wired directly to furnace blower, hence when blower comes on, it turn on, How? Any info please?**
A: This is my plan for this product. You could do this in two ways. Assuming your HVAC furnace blower is the same voltage, 120VAC in the US, you could wire directly off the feed inside the furnace that powers the blower. This will require understanding of electrical wiring and/or electrical schematic of the furnace. Although unlikely, this method may overload the blower protection circuit and probably voids the furnace warranty. Alternatively, you could use the house thermostat fan signal to control a 24 VAC relay, such as Functional Devices RIBU1C, to switch the 120 VAC powering the duct fan.

**Q: Any way to make it just go on full power instead of having to to push the button 5 times?**
A: Push the button 5 times. 
The controller is set up to program fan speed on start up but will maintain the memory on a power loss event. 
If you don’t want to push the button 5 times then just unplug it. Then you can plug it in one time🤔

### ⭐⭐⭐⭐⭐ Excellent blower
*by J***L on December 11, 2025*

I purchased this blower for use with an 8” independent insulated duct system that I installed in my attic to redistribute excess heat from the room my new wood burning stove is located in, to the rest of the house. The blower is very quiet even at full speed can move large a large volume of air. The variable speed control is nice although I do believe it would have been nice that the corded speed control’s form factor matched a US a rectangular switch plate/electrical outlet face plate dimension with and/or a faceplate mounting kit for a clean, permanent installation as the faceplate of the control is just a bit too big. Very happy with the unit so far
