Posted on April 24, 2017 at 11:07am 0 Comments

Eichler was one of the most famous Mid Century Modern home builders in the 50s and 60s. His homes are all over California. Owners of his designs have not had a whole house fan to help cool their homes until now. 

I just invented the first rooftop to pull 8000 CFM at just 505 watts through a 20 inch throat. The top can be hidden by a chimney looking enclosure and the bottom inside the home by a faux cabinet.

Hello,

I am a whole house fan and attic ventilation expert in Temecula CA. I started studying whole house fans in 2008 when my wife, Darlene, and I moved from Manhattan Beach. I would really like to share my knowledge with all of you but I want to be sure I don't antagonize you with more commercialization than you want. Please let me know your opinion and if you can, send me some examples of acceptable blogs and unacceptable ones.
