What Makes These the Best?

January 12, 2018

If you have an attic, the  Tornado ES-6400 is the best rafter mounted whole house fan in history. If you have no attic, the  Tornado ER-8000 is the first and only high performance rooftop whole house fan. 

No other source offers you 6,320 CFM using just one motor and blade in a rafter mounted system. No other source has a rooftop mounted whole house fan that pulls 8,000 CFM with a single 20 inch blade on one motor.
