When only the most powerful, advanced, and quiet whole house fan will do, the EPS Extreme Model is the ultimate choice. Designed for homes over 3,000 square feet, this fan combines cutting-edge engineering with premium comfort features — delivering an HVI-certified airflow of 4,267 CFM, so you can cool even the largest spaces quickly and efficiently.

The patented HushMount™ 2 technology keeps operation whisper quiet, and the Comfort Control Remote lets you customize your airflow with the touch of a button.
