Review: Wrong Manual and weak, but a great fan - It has been 18 months. The fan is strong and works well. The manual you get with it claims it has motion sensor and humidity sensor! That it does not. It is intimidating and confusing, showing you the circuits and some adjustments you should do. but it does not exist in this model. This is a very simple fan, you just need to remove the shell and detach the back if needed and place it on the other side of the wall/glass/board you are installing this on. Just look at the fan for a couple of minutes and you figure it out. The manual does not provide any useful information how to install it. just throw away the manual and use your own judgment it is an easy job. It is pleasantly quiet but weak. My master bedroom has a giant built in fan that is installed on the roof, so I just added this one to boost the vacuum process. But if you want to rely only on this fan alone to suck the humidity and odors, it will not do the job. By the way, what kind of seller put a wrong useless manual in the package? Perhaps someone who does not read English.

## Questions & Answers

**Q: What is the measurement between the fan and the check valve?  Need to shorten tube for my application so need to know how much I can remove.**
A: Hi, 
the duct between the fan and the check valve's measurement is 100mm(3.94 inch)
Hope that helps.
Good day!

Sincerely,
Allvent service team

**Q: Can the airflow be reversed?**
A: Cannot be reversed. The wiring is not polarized so reversing them would not work plus there is a damper that would close tight if the airflow was reversed.
