---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- Achieves large air volume and low noise by adopting dual suction fans. The Twin Aero Fan is equipped with a "double suction fan" with the top and bottom of the fan open. The two airflows allow for more efficient and smoother ventilation, increasing air volume and reducing operating noise compared to conventional types. Enables more comfortable 24-hour ventilation. The ventilation air volume is increased by increasing the suction volume with both suction fans and smooth airflow with less turbulence. Provide adequate ventilation with sufficient ventilation. Operation noise is reduced even when the air volume is increased. Even with 24-hour ventilation, it's quieter than inside the library. (Noise level: 40dB inside the library, 30dB whispering) Cleaning is now easier as the blades can be easily removed. Compatible with lightweight steel frames.
