Whole house fan 1500 CFM.MOV

This is a test of a powerful centrifugal blower tuned up for optimum air flow before being mounted in an attic to work as a whole house fan. Air flow is 1500 feet per second through a 14 inch duct resulting in over 1500 CFM! Now, what does that mean to you? If you live in a 3000 SF house with 10 foot ceilings, you have 30,000 cubic feet of air inside. This blower will move ALL that air in 20 minutes! But you don't need to move it all. If you just want a few rooms cool, and they are a total of, say, 600 square feet, then they get cool in about 5 minutes. Cool, right?
