Invisco makes two of the best whole house fans you can find. One is the INR8000 for rooftop mount, the other is the INA5400 for attic mounting.
Why are these the best?
- The only fans with infinitely variable speeds.
- The only fans with motors that run slow at low power.
- The rooftop has the first high air flow rain hat created in Australia.
- Invisco offers the only window automatic opener.
- Invisco offers the longest warranty in the industry.
INFINITELY VARIABLE SPEEDS
The Invisco Tornado line of fans offers you both an attic mounted version and a roof mounted version and BOTH fans are the FIRST AND ONLY whole house fans WITH INFINITELY VARIABLE SPEEDS. Infinitely variable speed control means you can run them all night for pennies.
LOWER POWER AND HIGHER AIR FLOW
The Invisco Tornado rooftop offers you higher air flow at lower power than any other whole house fan. How can we say that?
HIGHEST AIR FLOW IN A ROOFTOP MOUNT
The rooftop beats all other sources in airflow. In fact, only one other company offers a rooftop mounted whole house fan and that is QuietCool. Here is their rooftop – You can see that it pulls 2,730 CFM at 377 watts (That is the official Certified HVI-916 test result and is the true air flow, the 3,543 CFM is an exaggeration by QuietCool in defiance of the California Energy Commission.)
AUTOMATIC WINDOW OPENER
Invisco also offers an automatic window opener for security and remote control. Why is this important? If you want to turn your whole house fan on before you get home you will need a window open. If you have a single story home that means you cannot lock the whole house. But with the Invisco automatic window the window is opened just enough for air to enter, not a person. And the window is closed until you start the fan.
