Back view of the product (pay attention to the details, our product has a protective cover on the back, which hides the excess wire inside the main body instead of exposing it to the outside, making the product look more beautiful) Automatic start2018 upgrade technology, faster speed, larger air volume. Thermodynamic stove fans are designed to circulate warm air produced by wood/coal or pellet burning stoves with a normal surface temperature of 80C to 400C. Environmentally friendly and self-poweredThe thermoelectric module acts as a small generator to drive the motor of the fan. No batteries or electricity required Improved hot air circulation for greater comfort and 28% less stovetop wood is used. Safety DesignThe furnace support is treated with anodized aluminum, which is resistant to high temperature up to 752F (400C), and will not deform or discolor even if it works for a long time at high temperature. Longer Service LifeThe fan base is equipped with a bi-metal safety device, if the surface temperature exceeds 300C, the safety device will gently lift the front of the fan to protect the TEG and motor. one. Product performance indication 1. Fan working principle: The thermal power fireplace 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 generates cold and hot surfaces, and the thermal conductive sheet flows into the module and generates electricity to operate the fan. 2. Product structure: metal handle, heat sink, bimetallic heat conduction sheet, aluminum alloy fan Product weight: 560g Weight with packaging: 690g
