Features:1. Upgraded 10-blade fan: 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℉2. Environmental Protection: 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.3. Safety Design: 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.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. It is almost silent.5. Overheating Protection: 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:1.
