Okay, any manufacturer that has the words "big" and "ass" together in its name proves to be an interesting company to specify. That being said, Big Ass Fans is a great vendor for fan specifications. Contrary to their fans, they have more characteristics than just a "big ass" size.
Element, is designed for sound sensitive areas, with its motor's acoustic output no louder than a whisper. In addition to this feature, the complex electrical wiring monitors electrical consumption, the balance of the fan, and the temperature of the room. They are specified with industrial grade bearings that they claim will withstand the test of time.
The patented airfoil and wingtip aerodynamic design help stabilize air control to assist in a more cost efficient heating and cooling expenses.
This fan system allows for some cool and innovative extras such as speaker systems, surveillance cameras, smoke detectors, and more. All features can be easily controlled by an LCD remote installed into the wall.
Standard sizes are 12', 14', 16', 18', and 20' foot in diameter. Nine colors are able to be specified, with custom colorization available at an upcharge.
Ten year non-prorated warranty covers the LCD remote, onboard electric, and prime mover, with certain exclusions. Standard warranty for Element fan is 5 years with a factory installation.
It received a Green Product Award in 2009. However, there was no further information on how it received this award - I speculate that it is because of the cost efficiency. However, I could not find any information on the installation or its testing procedures.
