【Magnetic Stove Fan】: The stove fan with magnet has 4 reinforced blades made of high-quality aluminum and its thermal conductivity is higher and stronger than steel. The higher the temperature, the higher the speed, the larger the air volume, the lower the starting temperature, the longer the service life, the higher the corrosion resistance, and the more durable it is. (High-temperature-resistant magnets) 【Energy Saving】: The stove fan converts the heat generated by the fireplace into mechanical energy, drives the motor to rotate the blades, and the fan rotates to generate heat flow, close the air circulation, and ensure a uniform temperature. No batteries or electricity are required, which is economical and environmentally friendly and can save 15-30% wood. 【Inclined Design】: When installed on the pipe, our fan chimney is specially designed to tilt downward by 20°. The hot air then blows downward faster, accelerating the temperature rise. Note: It is recommended to install it 20-50
