Why we love it
Accelerates heating by 20%.
Integrates intelligent thermostat effortlessly.
Operates quietly below 39dB.
Main Highlights
【Accelerate Heating】The heater fan for radiator can greatly accelerate air convection by sucking air between the columns of your radiator. Feature 3 speed mode to maximize heating effectiveness, the radiator fans for home allow the heating output of column heater to be increased by 20% and room temperature to be rasied by about 2°C.
【Intelligent Thermostat】Our radiator heat diverter is equipped with an upgraded control box, which integrates electronic thermostat and the LED display showing real-time temperature. In "ECO" mode, the radiator ventilators activate at 30°C on default setting of L1 speed and automatically deactivate at 26°C, effectively preventing both the fans and heater from overheating.
【Flexible Placement】Made from high temperature resistant materials, these radiator fans have strong built-in magnets to ensure they stay securely in place without slipping. You can easily separate or combine the radiator booster fans for home based on your needs, and attach them directly to the radiator for hassle-free installation.
【Great Adaptability】The radiator blower fan is designed for magnetic metallic radiators with spacing, e.g. cast iron radiators, tube radiators, oil filled radiators, and provide a convenient and fast heating solution for users of these radiators. We recommend using triple set for rooms up to 20 m².
【Lower Noise】The smart radiator ventilator operates quietly with low energy consumption at L1 speed, producing noise levels below 39dB. This ensures a tranquil and comfortable atmosphere in the room, enabling you to fall asleep at night and work during the daywithout any disturbance.
