Bladeless Fan

Not to be confused with other bladeless fans, Exhale Fans by Exhale Fans are a class of their own. Based on the science of the great inventor Nikola Tesla, Exhale Fans follow in the foot steps of Tesla’s bladeless turbines. Blades are defined as a mechanism for clearing, wiping, scraping, or an arm of a propeller or similar rotary mechanism such as a electric fan. Exhale Fans have none of these qualities and therefore are bladeless. Exhale Fans use what they call “Laminar Flow Disk Array”. This array moves air into slow a vortex overtime by moving air molecules between the disks which then creates a laminar flow. A laminar flow is the effect of parallel layers of airflow with no disruption between layers. The rotation of the disks creates this flow which overtime increases creating a 360 degree output, efficiently mixing the air and stabilizing the temperature. This continuous airflow is said to feel like a cool breeze, as it passes over and around you. This greatly improves upon standard ceiling fans which only create a single downward push of air. Exhale Fans draws air up and into the fan while pushing the air out and down walls and other surfaces. Another thing that sets this design out is it’s use of a DC motor rather than a AC which are more commonly used. However this DC motor reduces watt requirements by 50-80 percent need to run the fan. The motor has a wireless control with 6 speeds. Depending on the speed of the fan, the motor uses between 3 watts at low speed and 35 watts high speed making it very efficient. Most common ceiling fans produce a lot of noise but not Exhale fans. At the highest speed of around 300rpms, only around 40dB of sound is created. That is the same amount of noise found in most quiet libraries. The small 34” size of the fans allows for easy placement in small rooms and works in rooms up to 20 feet by 20 feet.
