Feature:The upgraded 10-blade stove fan has faster speed and larger air volume. The thermodynamic stove fan is designed to circulate the warm air generated by the wood/coal or pellet burning stove. The normal surface temperature is 50°C~350°C /122℉~662℉The thermoelectric module acts as a small generator to drive the fan motor. No battery or electricity required! Improved hot air circulation can bring greater comfort, fuel consumption is as low as 17%, fuel saving, and enjoy heat from the stove faster.Furnace bracket is treated with anodized aluminum, with high temperature resistance up to 662°F (350°C), and will not deform or discolor even after working for a long time under high temperature.As the furnace heats up, the wood stove fan runs faster and faster, dissipating heat to the far corners of the room. It is almost silent.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.Color: BlackOperating temperature range: 122 degrees F to 662 degrees F (50 degrees C to 350 degrees C)Air volume unit: 160-200CFMSize: length: about 160mm/6.30in, height: about 185mm/7.28inPower: thermoelectric moduleMaterial: aluminum alloyPacking List:Fireplace Fan*1Note:The Heat powered stove fan does not bring direct temperature increase but only a tool to accelerate the heat transfer of the chimney.Due to the lighting effects and shooting angles, there is color difference in the product, please understand.Due to manual measurement, there is a tolerance in the product size.
