Sucking Axial Fan FR-BS EC-EE
The FR-BS EC-EE fan is a wall-mounted supply or extract fan for production halls, warehouses and workshops. The square casing makes direct wall installation easy, while the energy-saving EC motor complies with ErP 2026 requirements (EU Regulation 2024/1834) and allows smooth performance control.
About the product
FR-BS EC-EE is designed for supply or exhaust ventilation in facilities such as production halls, warehouses and workshops. The square housing with mounting holes enables direct wall mounting without additional structures.
Available in ten sizes, covering airflow from 1,710 to 21,000 m³/h. The energy-efficient EC motor reduces energy consumption and enables smooth speed control (0 to 100%). Models up to size 630 are powered at 230 V, while the largest models (710 and 800) run on 400 V.
The housing is made of powder-coated steel and the impeller of PP plastic. When used as an exhaust fan, it is recommended to protect the external outlet with a GS series gravity shutter. The unit is intended for indoor installation.

Why choose the FR-BS EC-EE
wall-mounted extractor fan?
Direct wall mounting without additional structures — The square housing with mounting holes allows the fan to be fixed directly to the wall of a hall, warehouse or workshop. For exhaust operation, it is advisable to protect the outlet with a GS gravity shutter.
Energy-efficient EC motor ready for ErP 2026 — The EC motor consumes significantly less energy than an AC drive and enables smooth speed control. The fan meets the requirements of Regulation (EU) 2024/1834.
Easy control and regulation — Output is smoothly adjusted via an EC potentiometer (0 to 100%) or the programmable HMI EC BMS controller, which can connect up to 8 fans.
