Short Cased Axial Fan FR-BC EC-EE
The FR-BC EC-EE short cased axial fan is designed as a component of simple duct ventilation systems. The energy-saving EC motor complies with ErP 2026 requirements (EU Regulation 2024/1834) and enables smooth performance control. The powder-coated steel housing ensures durability.
About the product
FR-BC EC-EE is an axial fan in a short cased housing, designed for installation in simple, straight duct ventilation systems. An axial fan provides a relatively high airflow rate, though its performance decreases as resistance increases, so it is not intended for complex duct systems.
Available in eight sizes, covering airflow from 1,710 to 10,800 m³/h. All models are powered at 230 V. 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 of PP plastic. The unit is intended for indoor installation and should not be used in corrosive, heavily dusty or high-humidity environments.
Key features
- Airflow ranging from 1,710 m³/h to 10,800 m³/h
- Motor power ranging from 98 W to 420 W
- Energy-efficient EC motor with smooth speed control (0 to 100%)
- Short cased housing for integration with a ventilation duct system
- Protection rating IP54, insulation class F
- Power supply 230 V
- Noise level from 59 dB to 69 dB
- Compliance with ErP 2026 (Regulation EU 2024/1834)
Why choose the FR-BC EC-EE
short cased axial fan?
Ready for duct integration — The short cased housing allows the fan to be inserted directly into a simple straight duct system. This solution is ideal for uncomplicated installations with low flow resistance.
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.
