5-BLADE HEAT POWERED STOVE FANNo battery or power supply is required!Why do I need a fireplace fan if I have a fireplace?The reason is that the heat of the fireplace rises, only around the fireplace, and the role of the fireplace fan is to blow the rising heat laterally so that the whole house can enjoy warmth.Working Principle:The fan is placed on the fireplace, and when the temperature of the base reaches 60 degrees, the electrothermal conversion module starts to start and generates current. The power generation module continues to work, generating current and driving the motor, and the motor drives the fan to rotate the blade. The fan continues to rotate, allowing the heat generated by the fireplace to spread out continuously, efficiently, and energy-efficiently, thereby quickly convecting heat throughout the space.PRODUCT INFORMATION:Name: Fireplace FanMaterials: anodised aluminium alloyShape: Christmas treeColour: black+red+greenSize: as shown in the pictureSpeed: 1450rpmBlade number: 5Noise: ≤32dBOperating temperature: 70-240℃ / 158-464℉Package Included:1 x Fireplace FanNotes:1.
