Example of use:
The RD roof fans can be used, for example, in apartment buildings with multiple units and internal bathrooms. The Helios extract air element AE Hygro detects the increasing humidity and controls the air volume via the opening valve. Using the Helios differential pressure controller EDR, the RD roof fan increases the speed and volume flow accordingly. The humid air is discharged. The Helios supply air element ZLA quietly supplies the required filtered fresh air from outside.
