Circulate the heat reasonably, no need to move to the fireplace, no longer bothered by the cold! Automatic and Quiet Operation -- 70-345°C is the normal operating temperature. The dissipation effect has a lot to do with product placement and oven temperature. If the oven temperature changes, the heat dissipation capacity will change accordingly! It is worth noting that the whole process is quiet (less than 32db)! High Efficiency -- Fan lotuses extend all around, different from straight extensions. When the temperature reaches around 70°C, the blades rotate, the heat is diffused directly into the air. environment without the need to go up and down.
