Caframo 810 Ecofan UltrAir Wood Stove Fan 

The 8" blades move up to 125 cubic feet per minute when used on freestanding wood stoves with a surface temperature between 212 Deg. F - 650 Deg. F (100 Deg. C - 345 Deg. C). The UltrAir Ecofan is an economical way to move air throughout your living space. This fan is ideal for those living off the grid or looking to increase the efficiency of their stove and use less fuel. Whisper quiet and completely assembled. Two year warranty.

Maximize the warmth of your woodstove by boosting its efficiency up to 30% with the innovative Ecofan. Using simple thermodynamic technology, the hotter your stove gets, the faster it quietly propels heat back into your living space using zero electricity. Peak performance occurs at surface temperatures of 212-650 Deg. F. A temperature-sensitive, bimetal strip on the unit automatically tilts it slightly to prevent overheating.

The new and improved Ecofan has a larger heat-absorbing surface area that multiplies its capacity to transfer the fire's BTUs into your environment. The two blade unit moves an impressive 125 cubic feet of air per minute. Made of anodized aluminum, fans won't rust or corrode.

This fan does not use any batteries or wall cords.

These fans have a thermoelectric module which acts as a small generator to power the fan's motor. When this generator module experiences a heat differential between it's top and bottom surfaces, it pumps out electricity. The bottom surface of the module is heated by the base of the fan, while the top of the module is kept cooler by the fan's top cooling fins.

The generator module is a unique semiconductor device that relies upon the Seebeck effect to generate electricity. When two dissimilar semiconductors (p-type and n-type) at the same temperature are connected together they establish a static electric potential difference. With the introduction of a temperature difference, heat flows across the joined semiconductors which in turn permits electrons to flow. With the electron flow or current comes the ability to power electrical devices such as the fan's motor.
