Hightest aerodynamic efficiency resulting from the computer optimized, three-dimensionally shaped impeller and stator blades combined with AC and EC motors.
QUIET
Low noise generation as a direct effect of the unique airflow through the diagonal fan and the guiding vanes.
ECONOMICAL
Reduced investment costs for the 3-step AC motors. Reduced operating costs with the energy saving EC motor, especially when it runs at partial load.
