------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------

Optimized fan blades deliver optimal performance for radiators and heatsinks. The speed switch allows you to change the maximum PWM rotation speed between medium, high, and extra-high speed. The fan frame, with its small tip clearance and funnel-shaped air outlet, achieves extremely high air pressure. This operation is barely audible at normal rotation speeds. The 6-pole fan motor and fluid bearings enable extremely smooth operation with minimal vibration.
