I used it in my basement to direct marijuana smoke outside through some 6" dryer tubing, which is merged into my dryer exhaust. This keeps my basement and house smoke/odour-free. I cannot predict how long it will last with marijuana smoke residue blowing through the fan blades etc, but for the money, it is well worth it. The fan is quiet itself, but with the fan mounted to a joist in the basement ceiling, the floor above it rumbles like crazy. There is a dial to adjust the fan speed. ## Images ![Inline Duct Fan 4 Inch 203 CFM with Variable Speed Control for Grow Tent, Ventilation, Plant Tent, Indoor, Garden, Ventilation Fan, Z4 Pipe Fan, Black - Image 1](https://m.media-amazon.com/images/I/71c4dpGtQ3L.jpg) ![Inline Duct Fan 4 Inch 203 CFM with Variable Speed Control for Grow Tent, Ventilation, Plant Tent, Indoor, Garden, Ventilation Fan, Z4 Pipe Fan, Black - Image 2](https://m.media-amazon.com/images/I/61iV6ASFbWL.jpg) ![Inline Duct Fan 4 Inch 203 CFM with Variable Speed Control for Grow Tent, Ventilation, Plant Tent, Indoor, Garden, Ventilation Fan, Z4 Pipe Fan, Black - Image 3](https://m.media-amazon.com/images/I/71u8Jjy3fDL.jpg) ![Inline Duct Fan 4 Inch 203 CFM with Variable Speed Control for Grow Tent, Ventilation, Plant Tent, Indoor, Garden, Ventilation Fan, Z4 Pipe Fan, Black - Image 4](https://m.media-amazon.com/images/I/61C27kWlbDL.jpg) ![Inline Duct Fan 4 Inch 203 CFM with Variable Speed Control for Grow Tent, Ventilation, Plant Tent, Indoor, Garden, Ventilation Fan, Z4 Pipe Fan, Black - Image 5](https://m.media-amazon.com/images/I/613I2LEQUWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ surprising quality for the price *by C***R on 27 August 2023* I was expecting a cheap outfit and got a pleasant surprise with nice quality really quiet well working product. haven't had it long but seems like a keeper ### ⭐⭐⭐⭐⭐ Works as described *by S***O on 26 November 2018* Product works as described.
