Quiet Cool Mfg. has a full line of whole house fans, attic fans and a few specialty fans for garages and wall mount applications.
The best selling line is the Trident series fans.
In this post I'm highlighting the Quiet Cool Trident 4.8 Whole house fan.
This whole house fan is one of the most common units Whole House Fan Installers stock and install.
It's a powerful fan that moves 4800 cfm (cubic feet per minute) of air with 2 speeds and only uses 537 watts of energy on high.
Compare that to your typical HVAC system energy usage and you start to see why so many people choose a whole house fan to save 50-90% on their cooling bills.
