Fireplace Fan Wood Burning Air Circulation Thermal Powered Fan

【4-Blade Chimney Fan for Higher Airflow】Designed with a motor and four blades, this stove fan efficiently distributes heat from the fireplace, quickly raising the room temperature. Suitable for fireplaces, it provides wide heat flow for optimal air circulation. 【Energy Saving Oven Fan Powered by Heat】No batteries or electricity required. This fan is powered by the heat generated by the fireplace or hearth. As the oven temperature increases, the blades rotate faster, saving fuel and reducing fuel consumption by up to 17%. 【Overheating Protection for Safe Use】Equipped with a metal strip at the bottom, this fan has automatic overheating protection. When the maximum operating temperature is reached, the metal sheet under the base bends to raise the fan base, reducing thermal contact and protecting the motor and thermoelectric module. 【Silent Operation for Enhanced Comfort】Operating below 25 decibels, this furnace fan operates quietly, enhancing the circulation of hot air in the room without disturbances. It ensures a comfortable and peaceful environment. 【Wide Operating Temperature Range】This fan operates at temperatures ranging from approximately 50°C to 350°C (122°F to 662°F), automatically adjusting the fan speed according to the oven temperature. The highest conversion rate is achieved at around 250-300°C.
