Axial suction fan FR-BS EC-EE
The FR-BS EC-EE fan has been designed to provide effective air circulation in production halls, warehouses, workshops, workrooms and other industrial facilities. The square housing makes direct wall mounting easy, and the energy-efficient EC motor with smooth speed control in the 0 - 100% range meets ErP 2026 requirements.
About the product
FR-BS EC-EE is designed for air extraction in facilities such as production halls, warehouses and workshops. The square housing with mounting holes enables direct installation on a building partition, without any additional structures.
Available in ten sizes, covering airflow from 1710 to 21 000 m³/h. The energy-efficient EC motor reduces energy consumption and enables smooth speed control (0 to 100%).
The housing is made of powder-coated steel, and the impeller blades are made of polypropylene. The unit is designed for indoor installation. We recommend protecting the outlet on the outside with a GS series gravity shutter.

Why choose the FR-BS EC-EE fan?
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 using the EC potentiometer (0 to 100%) or the programmable controller HMI EC BMS, which can connect up to 8 fans.
