| Advanced Blade Design - Leading Edge and Air Foil Chip |
| - Window Mount Ventilating Fan |
|
| To help for maintaining better indoor air quality, newly designed window mount ventilating fan is introduced. A newly designed fan blade is equipped at the products. |
|
| To optimize airflow performance of the ventilating fan, the new blade design applies advanced aerodynamic principle that minimizes any obstacle against the airflow. Air volume is maintained while rotation speed can be reduced, resulting lower noise level and power consumption. |
