Compared to tubeaxial fans, the fan modules consume up to 49% less power and provide up to 50% better air performance in nominal operation. The modules also provide up to a 7 Dba sound reduction. The EC version achieves even better heat dissipation and offers greater energy savings, thanks to demand-based airflow from speed control with 0–10 V control voltage.
The module’s external rotor makes the unit externally compact with a very shallow installation depth. Optional grill guards are available for the outlet and intake side.
