Regel-air® window rebate vents for wood and wood-aluminium windows
Regel-air® FFLHA Type 23 is a ventilation system that responds automatically to wind pressure for wood-aluminium windows. In wood-aluminium windows, the Regel-air® window rebate vents are to be used exclusively as supply air devices in conjunction with permanently operated fan-assisted extract ventilation systems.
They are available in two versions:
DThe first option is the Regel-air® FFLHA Type 23 ventilation system for wood-aluminium systems with a centre gasket in the frame.
The second option is the Regel-air® FFLHA ventilation system, types 24 and 44 , for wood-aluminium systems with a centre gasket in the window sash.
The basis for these window vents is the classic Regel-air® FFL. The window rebate vents are fitted into a housing in wood/wood-aluminium windows, which is milled into the window’s frame. The advantage of this installation method is that the centre gasket in the sash remains completely intact. The flaps in the ventilation modules respond 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 designs, such as arched windows, the ventilation systems can also be fitted vertically. The 14 RF, 23 RF and 24 RF vent models are suitable for this purpose. A return spring in the flaps of the window rebate vents ensures that the flaps reopen automatically after closing.
