5-Blade Wood Stove Fan, Silent Fireplace Fan with Thermometer, Heat-Powered Wood Stove Fan, Eco-Friendly, for Wood/Log Burners

[5-Blade Design] Equipped with 5 blades that offer faster speed and greater airflow than 4-blade designs.

[Fuel Saving] The heat furnace fan is designed to circulate the hot air generated by burning wood/coal or pellets, efficiently circulating the warm air throughout the room.

[Quiet Operation] The noise level of this furnace fan is less than or equal to 35 dB, providing you with a quiet environment.

[Eco-Friendly & Energy Saving] No batteries or power supply required, convenient to use, and cost-effective.

[Automatic Speed Adjustment] The fan speed depends on the furnace temperature. The higher the furnace temperature, the faster the fan speed.

When the oven temperature is sufficiently low (oven fire has burned out), the fan speed slows down until it stops.
