We installed in our gun room to help with moisture and it worked perfectly!
Reduce moisture and odor
By 'Marian', Reviewed on January 10, 2022
I purchased this vent fan to help with moisture and odor in my shed. The quality of the fan is great. I really like how you can set the run time and % of humidity. Before if I stored cloth or leather tool bags in my shed they would start to grow something on the surface. With the fan, I can control the moisture in my shed and save my tools.
Technology / simplicity / plug and play
By 'Melissa', Reviewed on January 07, 2022
Technology and simplicity combined to solve simple fundamental issues. I had been searching for a fan that would turn on and off in correspondence with temperature increase and decrease for ventilation in my attic. Gable vents alone don’t move air and therefore don’t enable attics to keep cool thus making your house hot. I debated hiring an electrician to hard wire thermostat controllers for standard box fans until I found this fan! It’s plug-and-play - simple- and my problems are solved. No electrician is needed. This will keep my attic cool and save me electricity by using a/c less. These fans can also be used and activated with humidity levels. Great for basements or crawl spaces. They are weather-resistant too! I absolutely love these fans.
Great!
By 'Rhys Evans', Reviewed on July 15, 2021
Because of the hot and humid weather, sometimes I can found condensation on the wall. I came across this product by chance, and as it was inexpensive, I bought it to give it a try. However, it really impressed me, the machine made a big difference in removing the condensation, I was really satisfied with it.
Efficient dehumidification
By 'Jessica Miller', Reviewed on May 12, 2021
This fan installed easily and is actually pretty quiet. The thermostat works well and while it's not totally accurate in terms on actual temp vs markings on the dial. But it does help reduce the humidity in my house.
It is very useful
By 'Ashlyn Magana', Reviewed on April 29, 2021
I have mine installed just like the picture. The fan has been a great help to my basement, as there is hardly any airflow in and out of the place. The noise level on a fan this big is low and very smooth. The ball bearing has little to no resistance, and the controller is a nice feature for giving off alarms and eco-mode. The eco-mode is great if you just want to set it and forget it. I have mine working this way and even after a power failure, the fan went back to the last setting it had saved. A quality fan for a fair price.
very useful
By 'Iris Flowers', Reviewed on April 04, 2021
My basement is very damp, which annoy me very much, so I decided to buy an exhaust fan, which controls the temperature and humidity of my basement very well, and I think it is very useful
Good product
By 'Keri Meyers', Reviewed on March 14, 2021
This is the best ventilation fan I have not used yet. Can be easily installed in my crawl space. Through the digital control, you can set the temperature or humidity, thus increasing the versatility. About a week or two after installing this machine, the humidity in my crawling space dropped. Yes, I would recommend it to my friends.
Very effective ventilation fan
By 'Claire Watson', Reviewed on March 07, 2021
VentirPro-S2 has left a deep impression on me. The manufacturing quality is very good, the operation is simple, and the price is very reasonable. I plan to buy 2 more. These fans help keep the crawl space dry and bring a much fresher smell to the space. The instructions are clear and easy to understand, so you know how to run it correctly. Overall, a great product.
Great fan for damp basements
By 'Skye Haworth', Reviewed on February 28, 2021
My basement accumulates a lot of moisture throughout the day. If there is no fan, the wooden structure of the basement will be infested by termites. However, after a few weeks of installation, I noticed that I can breathe more easily and there is less dust around. The fan has temperature and humidity sensors, if set correctly, both can work normally. The base cover is also stainless steel, which is highly resistant to stains or other mold growth.

Hi Sage, The unit has a double-ball DC motor that drives the built-in 120mm double-blade fan, which can move 240 CFM while reducing noise and power consumption, which is better than AC fans. What's more, the noise of this noise is 0-48 dBA. So, you can don't worry about the noise.
