Longer Lifespan: The fan base is equipped with a bimetallic safety device; if the surface temperature exceeds 300°C, the safety device will gently lift the front of the fan to protect the TEG and motor. Performance Index: Fan Operating Principle: The floor heating stove fan uses thermoelectric technology to convert the temperature difference into electrical energy. There is a unique thermoelectric module in the center of the fan. When heated, the module creates hot and cold surfaces; the heat sink flows into the module and generates electricity, causing the fan to run. Product Structure: Metal handle, heat sink, bimetallic heat conduction plate, aluminum alloy fan blades Package Contents: 1 x 4-Blade Heater Stove Fan Note: The temperature must not exceed 752°F when using the stove fan.
