Product information " Window rebate vents FFL Type 21 RF"
The Regel-air ventilation system ® FFL Type 21
Our Regel-air ventilation system FFL Type 21 is an automatic, self-regulating window rebate vents. It is made of PVC and features automatic airflow limitation. This makes it very easy to prevent damp and mould damage. The pressure difference prevailing on the building is utilised to ensure automatic air exchange and the supply of fresh air to all rooms. Fresh outside air simply flows into the interior of the room through the Regel-air ® FFL window rebate vents.
To prevent draughts, the ventilation flaps automatically close when wind pressure increases. Controlled air exchange is guaranteed when the system is installed correctly.
The FFL ventilation systems operate on a purely mechanical principle. No power supply is required for this energy-efficient ventilation.
We recommend fitting every room with Regel-air ® ventilation systems. This ensures that the entire flat is reliably ventilated.
