## Description

desertcart.com: VIVOSUN Inline Booster Duct Fan 4” 106 CFM with Speed Controller, HVAC Exhaust Ventilation Fan with Low Noise for Basements, Bathrooms, Kitchens, Attics, Grow Tents : Patio, Lawn & Garden

Review: Very good product recommend it works extremely well - I was extremely happy with this product I did expect it to be the size that it was and it was which is sometimes surprising. The power that this thing has the fan to suck the air from one part of the house to the other is absolutely wonderful I use it for my attic space to keep the hot air out in the summertime.
Review: This Is worth it in every aspect - This exhaust fan works great. I have had it and tested it for over a month now. It is very quiet, I wish bathroom motors were this quiet, next the power dial also controls the speed of the fan. the fan speed is completely adjustable this is a HUGE bonus. Most air duct exhaust fans are either on or off, this one has fan speed control. It hooks up pretty easy the length of the cord is about 6 feet which is good. The on off switch is the dial, so the only negative is the switch position. I wish the switch was closer to the outlet and further away from the actual inline booster module.

## Features

- Durable: The fan has a strong motor which features a permanently lubricated bearing that operates quietly and requires no maintenance; The quality steel housing makes it sturdy and built to last
- Adjustable Speed: A variable speed controller on the power cord enables the fan to run at different speeds; With this speed switch, you can adjust it to the desired airflow level
- Compact But Efficient: This duct fan is compact and lightweight enough to be installed in areas with little available space; With a diameter of 4 inches, speed of 2990 RPM and 106 CFM airflow
- Low Noise: Superior balanced centrifugal impeller for long service life & quiet operation; A less than 28 dB noise level does not have any harm and will not disturb your life
- Wide Applications: You can have it in bathrooms, kitchens, workshops, basements, attics and etc, in order to boost airflow in HVAC systems; Also, it can be used in grow rooms as intake fans or exhaust fan
- To maintain optimal performance of the exhaust fan, clean the fan after the first week of use with the carbon filter connected, and then clean regularly based on usage conditions

### ⭐⭐⭐⭐ Too loud.
*by A***. on December 23, 2025*

I'm questioning whether there is something wrong with this fan. It works but it is very loud. I found that a wire from the motor was looped up and touching the fan blade. I pushed it down with hemostats. The fan runs quiet as expected now.
