Regel-air ® FFLH – window rebate vent for wood and wood-aluminium windows
The basis for the vents Types 24 and 14 is the classic Regel-air ® FFL. The window rebate vents are fitted into a housing for timber and timber-aluminium windows, which is milled into the window’s frame. The advantage of this installation method is that the centre gasket is fully preserved during sash. The flaps in the ventilation modules react to wind pressure in exactly the same way as in the FFL ventilation system and close as wind pressure increases.
To ensure the minimum air change rate is achieved in special constructions, such as arched windows, the ventilation systems can also be fitted vertically. A return spring in the flaps of the window rebate vents ensures that the flaps open again automatically after closing.
The Regel-air ® window rebate vents FFLH Type 24 is available in white, light grey, clay brown and anthracite.
