We are pleased to provide a performance comparison document for our large ceiling fan, "THE FIRST FAN." The shape of our blades is designed to mimic the wings of a glider, following the principles of fluid dynamics to deliver ideal airflow. In contrast, conventional blade shapes can cause turbulence due to their design, leading to air resistance and resulting in uneven air distribution (temperature variations indoors). This is just one example, so please download the document for more details and take a look.

"The First Fan" is a large ceiling fan with a low noise design that achieves high-speed rotation through W-WingLet (patent pending). With noise levels around 40 dBA, which is the quietest in the industry, it provides a strong breeze that can lower the perceived temperature by 4 degrees in summer, and from autumn to spring, it circulates warm air from the ceiling throughout the space, ensuring comfort year-round. This low-noise design has been recognized and adopted by the National Institute of Japanese Literature. Additionally, while the facility has a reinforced concrete ceiling, installation is carried out by anchoring (with strict tensile testing conducted). Compared to large fans made overseas, it is compact and lightweight, allowing for installation without regard to the building's structure. [Features] - Noise level around 40 dBA, the quietest in the industry - Low noise design with high-speed rotation using W-WingLet (patent pending) - Tornado convection delivers 1/f wind throughout the space - Blade diameter of 5m covers an area of 27m x 27m (729m²) - Airflow equivalent to 50 factory fans (blade diameter 45cm) with the power consumption of 3 units - Airflow equivalent to 110 factory air conditioners (10 horsepower) for dispersing cool air *For more details, please refer to the PDF document or feel free to contact us.

The "Sky Method" is a construction technique that uses aluminum foil, which excels in reflecting radiant heat, to apply Sky Sheets. It provides a uniform heat insulation effect regardless of the skill level of the workers or the weather conditions during the work. Additionally, it also prevents rain leaks, which are common in folded plate roofs, allowing for both heat and rain leak measures to be implemented simultaneously in one installation. Please feel free to consult our company when you need our services. 【Features】 ■ Significantly reduces temperature rise in folded plate roofs ■ Greatly improves workability ■ Achieves stable heat insulation effects and rain leak prevention *For more details, please refer to the PDF materials or feel free to contact us.
