Regel-air window rebate ventilator FFLHmax type 44 set

The Regel-air FFLH ventilation system is a self-regulating, plastic window rebate ventilator with automatic airflow limitation to prevent moisture and mold damage. It utilizes the pressure differential within the building to ensure air exchange and supply all rooms with fresh air. Fresh outside air flows through the Regel-air® ventilator modules into the interior. To prevent drafts, the ventilator flaps react automatically and close when wind pressure increases. Proper installation guarantees controlled air exchange. The window rebate ventilator operates purely mechanically; no electrical power is required for this energy-efficient ventilation system.
