Airflow Performance

5/5

Haiku’s patented motor and airfoil system can move more than 19,000 cubic feet (538 cubic meters) of air per minute. The brushless DC motor and aerodynamic airfoil design minimize mechanical friction and wind resistance, keeping airflow consistent throughout the coverage area.

Airflow Coverage Area

5/5

Haiku’s patented motor and airfoil system can move more than 19,000 cubic feet (538 cubic meters) of air per minute. The brushless DC motor and aerodynamic airfoil design minimize mechanical friction and wind resistance, keeping airflow consistent throughout the coverage area.

Annual Energy Use

5/5

With a max power draw of only 56 watts, Haiku’s annual energy use is negligible compared to traditional airflow solutions like A/C. The fan has been recognized once again in 2020 as “Most Efficient” by ENERGY STAR®, with efficiency that reaches up to 1,533 CFM/watt. When this efficiency is maximized with Fan Eco through the Haiku mobile app, Haiku ranks as the most efficient ceiling fan ever made.

The fan’s air movement and coverage area allow businesses and homeowners to save year-round on cooling and heating costs by reducing the need for A/C in summer and improving the circulation of heated air in winter. These energy savings more than offset the fan’s modest estimated annual operational cost of US$3.70—just $0.01 per day.

Controls

5/5

Haiku’s suite of available controls includes a premium multi-function remote and slim wall holder. The remote allows users to adjust fan speed and LED brightness levels and enable Sleep, Timer, and Whoosh modes. Built-in SenseMe technology uses the fan’s temperature, humidity, and motion sensors to monitor room conditions and automatically adjust operation to maintain occupant comfort. With Haiku’s mobile app, users can set airflow and lighting preferences, schedule routine operations, and access the fan’s four special operational modes—including energy-saving Fan Eco—for automatic comfort. Fan owners can also integrate with ecobee smart thermostats or use Google Assistant and Amazon Alexa to control their fan and optional LED with voice commands.

Sound Level

5/5

Haiku’s permanent-magnet motor eliminates brush friction and minimizes mechanical noise, while its aerodynamic airfoils produce practically no wind turbulence. Measuring at less than 35 dBA at max RPM, Haiku offers nearly silent performance, with sound level comparable to a whisper. When run at low speeds for destratification, the fan’s operational sound is imperceptible at occupant level.

Durability

5/5

Haiku features hand-balanced airfoils made from extruded aluminum, Moso bamboo, or matrix composite guaranteed to never droop or crack, and its extremely lightweight construction puts virtually no stress on the fan’s hardware. Haiku’s brushless DC motor runs cool with minimal heat output, maintaining efficiency and long life.

Warranty

5/5

Haiku features a non-prorated 5-year residential and 3-year non-residential warranty (3-year residential and 2-year non-residential for outdoor models). Big Ass Fans’ warranties are noteworthy for their straightforward terms, avoiding abundant fine print and exclusions and adding to customer confidence.

Warranty terms vary by region. See bigassfans.com/product-warranties/ for full details.

Performance Certifications

5/5

Haiku fans have undergone extensive third-party testing by the U.S. Department of Energy and received multiple international and ENERGY STAR® certifications to guarantee accurate performance claims and adhere to industry regulations and standards.

Required Maintenance

5/5

Haiku features a balanced mounting system, corrosion-resistant airfoils and ball bearings, and a gearless direct-drive motor that quickly dissipates heat. The fan should be wiped clean as needed, especially in demanding industrial or outdoor applications, but otherwise, Haiku requires minimal maintenance.

Motor and Drive Protection

5/5

Haiku is rated IPX2 for protection against falling water droplets and is damp-rated for covered outdoor use. The direct-drive motor’s slim, efficient design produces virtually no heat and is shielded from exposure to dust and other airborne particles, while its stainless-steel ball bearings resist corrosion caused by moisture and oxidation. A foam block in the motor shaft and sealed LED kit offer further protection from the elements in outdoor applications.

Static Safety Features

5/5

Haiku’s secure mounting options and durable airfoils engineered to resist impact damage and corrosion from the elements. The fan’s gearless direct-drive motor runs cool with minimal heat output, while its 17-pound (7.7-kilogram) average weight ensures that it never exceeds the load limits for a standard fan junction box.

For high ceiling applications and those experiencing wind gusts, Haiku’s optional guy wires secure the fan hub to the ceiling structure, providing additional stability, Outdoor Haiku models feature corrosion-resistant stainless-steel ball bearings for smooth operation and a foam block in the motor shaft to protect against water intrusion.

Dynamic Safety Features

5/5

Haiku undergoes extensive safety testing at Big Ass Fans’ accredited research lab, including airfoil impact trials as well as wind and salt spray testing. To further assess product quality, Haiku is hand-built and tested during the production process for balanced, quiet performance.

Safety Certifications

5/5

Haiku’s safety is proven through rigorous testing, an international CB Test Certificate for passing CB Scheme safety certification, and ETL-listing to UL507 and CSA Standard 22.2 No. 113. At Big Ass Fans’ research lab, Haiku has undergone successful impact testing, mount tensile testing, and stress testing of hub and airfoil systems, the results of which far surpass competitor testing in scope and performance.

Facility Integration

5/5

Like other Big Ass overhead fans, Haiku offers integration with building management systems (BMS) with its optional 0-10 VDC module for convenient, centralized facility control.

Patented and Proprietary Features

5/5

Featuring 15 patents and more than 75 design awards, Haiku is renowned for its innovative technology and appealing design.
