When it comes to fans and efficiency, blade size matters. The blades on these fans range from 6 feet to a staggering 24 feet! The larger the fan blade, the slower the fan has to turn to create the same amount of air. This means reduced noise and increased efficiency... These architectural fans by Big Ass Fans utilize an electronically controlled, gearless motor (most fans have gears that audibly buzz and reduce efficiency) to ensure silent operation and quick cooling. Other features include:
- Airfoil and Winglet: increases download velocities to stabilize air movement. Improved air circulation
- Oil-free, permanent magnet prime mover for silent operation. High torque at very low speeds with industrial-grade bearings for long lasting cooling.
- Customizable platform to allow integration of surveillance cameras, audio speakers, smoke detection
- Compact Wall controls provide ability to control multiple fans with one controller. Easy-to-read LCD display that can be integrated into a building's automatation system.
