Feature: 1. 1.Start at Low Temperature: upgrade technology, faster speed, greater air volume. The thermodynamic stove fan is designed to circulate the warm air generated by the timber/coal or pellet burning stove. The normal surface temperature is 50°C~350°C /122°F~662°F, and the fireplace temperature is above 80°C/176°F. The fan will Work. 2. 2.Environmental conservation and Self-powered: The thermoelectric module is used as a small generator to drive the motor of the fan. No need for batteries or electricity! Improved hot air circulation can bring greater comfort, fuel consumption is as low as 17%, fuel saving, and enjoy heat from the stove faster. 3. 3.Security Design: Furnace bracket is treated with anodized aluminum, with high temperature resistance up to 662°F (350°C), it will not deform or discolor even after working for a long time at high temperature. 4. 4.Silent Operation: As the furnace heats up, the wood stove fan runs faster and faster, dissipating heat to the far corners of the room, and the hot air circulates throughout the room, which means less consumption and higher efficiency. It\u0027s almost silent. 5. 5.Overheat conservation: The built-in bimetal strip at the bottom of the stove fan is designed to slightly raise the edge of the fan when it is close to the maximum operating temperature to protect the motor and the thermoelectric module.

Specification： Dimension：170*110*200mm Blade No.：4 blades Color：Black CFM：180-220 Speed：1400rpm Noise：≤24dB Work temp.：50°C~350°C Material：Aluminum Net weight：800g Gross weight：850g Package List: 1*Fireplace Fan Note: 1. Do not carry the base of the stove, and do not place the stove on an unprotected surface when it is hot. 2. To move or carry the fan, always use the retractable handle when wearing gloves. Please keep children away from children when using. 3. If the fan does not rotate, you can increase the temperature of the fireplace, or apply some lubricating oil to the motor shaft to reduce friction. 4.The speed of the fireplace fan will change with the temperature. The higher the temperature, the higher the speed, and the lower the temperature, the slower the speed. When the furnace temperature is so low that the fire is extinguished, the speed will slow down until it stops. 5.Please allow slight tolerances in size due to manual measurement, and lighting in photography may result in difference in color than it is in real life.
