Product information " Window rebate vents FFLHA Type 23 RF"
The Regel-air ® FFLHA Type 23 RF ventilation system for horizontal and vertical installation
The Regel-air FFLHA ventilation system is a self-regulating window rebate vents made of PVC with automatic airflow limitation to prevent moisture and mould damage.
The pressure difference prevailing on the building is utilised to ensure air exchange and supply fresh air to all rooms. Fresh outside air flows into the interior through the Regel-air ® ventilation modules. To prevent draughts, the ventilation flaps s react automatically and close when wind pressure increases. Controlled air exchange is guaranteed by professional installation.
The window rebate vents operates purely mechanically; no power supply is required for this energy-efficient ventilation system. In timber- aluminium window, the Regel-air window rebate vents must be used exclusively as a make-up air system in conjunction with permanently operated, fan-assisted extract ventilation systems.
We recommend fitting every room with Regel-air ® to ensure that the entire flat is ventilated.
