Extension Add-On Module: Expands the performance of your existing Radboost radiator fan system for wider radiators or larger rooms.
Automatic Operation: Connects directly to your Radboost base unit, operating in sync with the main thermostat sensor.
Quick Magnetic Installation: Simple magnetic mounting system allows fast, tool-free fitting to all standard radiator types.
Improved Heat Circulation: Increases warm air projection from the radiator for faster, more consistent room heating.
Energy-Efficient Design: Low 1.65–3.3 W power draw maintains energy savings while enhancing comfort.
Quiet Performance: Operates below 20 dBA, ensuring near-silent airflow during operation.
Expandable System Setup: Multiple Extension Sets can be daisy-chained to match extra-wide radiators or high heat output requirements.
The Radboost Radiator Booster Fan Extension Set is designed to expand the coverage of your existing Radboost Single or Double Pack system. It connects directly to your current base units, providing additional airflow to improve heat distribution and comfort in larger rooms or across wider radiators.
Important: This Extension Set can only be used with the Radboost Single or Double Pack base fan units. It is not a standalone system and must be connected to an existing Radboost setup for power and control.
Each PRO-5 fan within the Extension Set increases warm air circulation from your radiator, helping to heat the room faster while maintaining energy efficiency. When connected to the main Radboost unit, it runs automatically in sync with your system’s thermostat sensor for hands-free operation.
The Radboost Extension Set installs in minutes using built-in magnetic mounts. It fits all standard single, double, and column radiators, and the connecting cable included ensures seamless integration with your existing fans.
Designed for whisper-quiet performance under 20 dBA, this low-power 1.65–3.3 W fan operates efficiently without adding noise. Multiple Extension Sets can be added in series to suit extra-wide radiators or large heating areas.
