Customer Questions
Can I install the fan in a drop ceiling or hidden space?
Yes, you can. The prioAir is compact and quiet, making it a great choice for ceiling or wall cavities where space is limited.
Can the prioAir fan work for both exhaust and supply air?
Yes, it can. You can use it to pull stale air out or push fresh air in, depending on how your duct system is set up.
Can I mount the prioAir fan in any direction?
Yes, you can install it horizontally, vertically, or at an angle. It’s designed to perform well in any position, giving you flexibility during installation.
My duct run is very long with several elbows, can prioAir still work well?
Yes, it will, but longer ducts and multiple turns can reduce airflow. Choosing a larger or more powerful model can help maintain strong performance, and keeping your ducts as straight as possible will improve efficiency.
