High efficiency and integrated control functions. Energy-efficiency class IE4 exceeds the minimum requirements of the standard.
These fans are suitable for low air flow rates of up to approx. 30,000 m³/h. Fan wall configurations of any size can be constructed. Connecting multiple fan units to form a fan wall generates high air flow rates, saves space and provides redundancy. This type of fan is designed to be extremely smooth running and generate virtually no structure-borne noise emissions.
