About VIVOSUN Variable Fan Speed Controller, Speed Adjuster for Inline Duct Fan in Ventilation System
Overall Feedback:
84% positive
80% appreciated the adjustable settings
I have found the control to have unbelievable variable speed and very fine adjustment control.
I adjusted the controller to achieve the best balance between airflow and noise.
I can adjust the device by plugging it into the wall and using the dial to adjust the current flow.
I adjust the speed setting by turning the small screw slightly clockwise until I get the lowest speed that I like.

71% liked its powerful airflow
I can now reduce the flow to less than half the capacity for my outdoor waterfall pump as the device works perfectly.
89% found it easy to install
Installing the controller was easy, just plug it in and it's done.
After installing the device and turning it down to 25% speed, everything is now quiet and fine.
85% appreciated the mounting options, but 15% found them limited
I can provide information on how to mount the unit by opening the back and adjusting the potentiometer with a screwdriver.
73% liked how quiet it operated
I compared the noise level of the fan to that of a vacuum and found that it reduced to the sound of an actual fan.
