About Hon&Guan 3 Inch Duct Fan, High Efficiency Inline Fan Mixed Flow Ventilation System Exhaust Air Fan
Overall Feedback:
82% positive
65% appreciated the adjustable settings, but 35% found them confusing
Adding a speed controller to the noisier ones quiets them down a lot by reducing the speed a bit and still provides significantly more air flow.
I am using the fan on low speed with an adjustable timer for daytime operation.
I experienced smoke coming from the fan after a while, indicating a problem with its adjustability and controls.
70% liked its powerful airflow, but 30% found it insufficient
After setting the fan on low on one of the ducts, I felt a substantial air flow instead of barely moving any air.
For my purposes, the air flow feels weak at around 50 cfm.
I am disappointed with the airflow capacity of the fan. It barely has any draw and is barely noticeable unless my hand is totally blocking the port.
The fan noise level is quite loud compared to the room noise level. It measures 65-68 db near the fan body and 74-76 db at the exhaust vent.
76% praised its long-lasting durability, but 24% experienced premature failure
I am not sure about the durability of the fan, but so far it is a solid replacement.
The fan may be suitable for an outdoor greenhouse or a place where people do not spend a lot of time in, but not for home use.
I find the fan to be wimpy and not powerful at all.
81% found it easy to install
I installed the product several months ago and wanted to live with it before writing a review.
Installing the GE push-button timer was easy and it worked perfectly. The fan has multiple installation options for timers, multi-speed, and three-way switches, and the user manual includes diagrams for all of them.
The installation was easy. I replaced a 180 dollar s&p fan installed by the builder which died in less than two years. The HVAC company was asking 40 dollars to replace it with no warranty.
67% appreciated its energy efficiency, though 33% weren't satisfied
This fan may not be suitable for home use, but it could work for an outdoor greenhouse or a less frequently occupied space.
66% liked the easy-to-clean design, but 34% found it difficult to maintain
I repaired the fan with electrical tape after noticing smoke coming out of its seams. Without sealing them off, fumes will leak back into our environment.
The fan body is not airtight where it mounts to the reducer ends.
This fan may not be suitable for home use, but it could work for an outdoor greenhouse or a place where people don't spend much time.
The fan is powerful but very noisy.
70% appreciated the mounting options, but 30% found them limited
I have mounted the fan horizontally between the two vents on a rafter tie with flexible duct hose running to each.
I mounted the fan horizontally on a rafter tie, centered between the two vents, with flexible duct hose running to each. Installing this fan was a breeze.
I suggest mounting the fan on a foam rubber pad to dampen the low frequency rumble.
85% liked how quiet it operated, but 15% found it too loud
When I operate the fan, I can barely hear its low noise level.
I selected this fan for its low noise level and high CFM rating, and it has not disappointed. The fan is barely audible when operating and has solved the issue of smoke in my shop.
The fan has a low noise level and is barely audible while running. It also has a lifetime warranty and costs less than the previous fan I installed.
I have complained that the fan's noise level is much louder than advertised, comparable to a room-sized air conditioner.
