• Compact Size--8.7 x 6.7 x 3.6 inches, the material of the stove fan is aluminum.
• No Batteries or Electricity required--The wood burner fan uses heat from the stove surface to spin, adjusting its speed automatically with the stove surface temperature.
• Longer lifetime--There is a Bi-metallic safety device at the base of the stove fan. If the surface temperature rises around 300℃, the safety device gently elevates the front of the fan to protect the TEG and motor.
• Whisper-quiet--The only moving part of this heat powered fan is the blade assembled. You don't even know the stove fan is there, but you will FEEL the WARMTH!
• Less Consumption, More Efficiency--The stove fan will help reduce the fuel consumption and make the room warmer quickly.
