Energy Saving: The 6-blade heat fan can convert more heat while improving stability. The energy conversion efficiency is very high, saving more energy. Self-powered: The wood stove fan is designed to circulate the hot air created by a wood stove / coal or pellet burning operating at normal surface temperatures between 87C and 350C. Overheat Protection: When the temperature is above 350 degrees Celsius, this fireplace fan will gradually insulate the chimney contact surface and the fan will stop working to protect the normal operation of the machine. Quiet without Noise: Newly designed blade, larger air volume, with noise lower than 35dB. The only moving part is the blade assembly. Say goodbye to terrible noise, you will enjoy warm air in a quiet and comfortable environment. Easy Operation: There is a hook on the stove fan for easy carrying. No installation is required, just follow the instructions to place your stove fan to the side of the woodstove or fireplace, not directly in front or near it.
