Axial suction fan FR-SG EC-EE
The FR-SG EC-EE axial fan removes exhaust air from cooling, heating and ventilation units. Equipped with a protective grille and an energy-saving EC motor, it complies with ErP 2026 requirements (EU Regulation 2024/1834). Smooth speed control makes it possible to adjust performance to current demand.
About the product
FR-SG EC-EE is a sucking axial fan that extracts air from cooling, heating and ventilation units. The energy-efficient EC motor reduces energy consumption and enables smooth speed control in the range of 0 to 100%.
Available in ten sizes, covering airflow from 1710 to 21 000 m³/h.
The housing is made of powder-coated steel, and the impeller blades of polypropylene. The protective guard secures the impeller against direct access. The unit is intended for indoor installation; it should not be used in corrosive, heavily dusty or high-humidity environments.
Key features
- Airflow ranging from 1,710 m³/h to 21,000 m³/h
- Motor power ranging from 98 W to 1,390 W
- Energy-efficient EC motor with smooth speed control (0 to 100%)
- Protection rating IP54, insulation class F
- Zasilanie 230 V (modele 250 do 630) lub 400 V (modele 710 i 800)
- Noise level from 59 dB do 78 dB
Why choose
the FR-SG EC-EE fan?
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, and rated values are given for the best efficiency point (BEP).
Robust, durable construction — The powder-coated steel housing and PP plastic impeller ensure resistance and long service life. A protective guard prevents direct access to the impeller.
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.
