Regel-air® ventilation system FFL – for precisely controlled air flow rates
The Regel-air® window rebate vent FFL is installed concealed in the upper, non-condensing area of the windows. When the window is closed, the ventilation system is not visible from either the inside or the outside.
As wind pressure increases, the system’s ventilation flaps close automatically. This prevents draughts. The ventilation flaps open again automatically as soon as the wind pressure decreases. This ventilation system operates automatically, is purely mechanical and requires no electricity.
