Below you see the rooftop in final test with the top spinning as air is forced up and through it. This is the most effective rain top ever made for rooftop whole house fans because it offers air unobstructed flow.
This Tornado rainproof top is the most effective rain hat in history because it allows perfect air flow at all motor speeds and perfect rain deflection. Note that if there is no wind then rain falls straight down and off the top. If there is any wind the turbine rotates and the blades deflect rain drops. Note that the motor has infinitely variable speeds so it can be run at just 10% of top speed and the power in watts is almost exactly 10% of full power or about 50 watts. Below is the price based on the industry standard average price per CFM of 28 cents.

Installation is the same as putting a simple pipe through your roof. In this case the pipe is our 24 inch diameter shell with motor and blade inside. The rain hat is mounted on top of the motor and blade shell. This work should be done by a licensed roofing contractor and you can find one locally in almost every city in the world. The shell with the motor and blade can be on top of your roof or below it. The assembly includes a damper so air cannot fall down when the motor is off.
If you are concerned about the look of the rain top on your roof you can ask for a surround to make it look like a chimney. You can see examples below. These are low cost options.
And in your home you can ask for a cabinet to match your other cabinets to hide the steel shell with the motor inside. See examples below. Also low cost options.
This fan is very quiet. It was measured at just 61 Db when 15 feet away.
