Airflow straightener (for Downflow units only)
Reduction of sound pressure level by airflow straightener 15x15x15 mm
Increase of electrical power consumption by airflow straightener 15x15x15 mm
The numbers 1-5 and 7 stand for the construction sizes 1-5 and 7.
With the application of an airflow straightener grid, which is
mounted onto the fan injection nozzle, the sound emission is
reduced. The electrical fan power consumption is increased.
In the diagrams below the absolute power increase and
the sound reduction is displayed in dependance of the air
volume flow for the construction sizes 1-7.
