Bees use honeycomb structures to store honey and rear their larvae. ZIEHL-ABEGG already utilises the advantages of hexagonal lightweight design in ZApilot to deploy material resources efficiently. For ZAflow, the advantages of the honeycomb structure were applied once again and adapted to offer efficient airflow guidance with minimal impairment of the air stream. In confined installation situations, ZAflow can improve the inflow to the impeller and contribute to a reduction in noise levels.
Centrifugal fans react significantly more sensitively to disturbances in the incoming air on the suction side than on the pressure side. This is where ZAflow applies and helps improve the inflow to the impeller. In confined installation situations, a reduction in the noise level can thus be achieved. Experience has shown that the overall sound level of a typical ventilation system can be reduced by approximately 3 to 6 dB depending on the installation situation.
If the use of ZAflow yields no improvement, this indicates that the installation situation is already favourable and the use of ZAflow is not required. If a positive effect is demonstrated through its application, the straightforward assembly and handling of ZAflow allow simple retrofitting of existing systems.
