Regel-air window rebate ventilator FFL type 21 RF set

The Regel-air FFL ventilation system is a self-regulating, plastic window rebate ventilator designed for installation in pairs. It features automatic airflow limitation. The Regel-air FFL window rebate ventilator is concealed within the upper, un-rigged area of ​​the window. When the window is closed, the ventilation system is invisible from both the inside and outside. As wind pressure increases, the system's ventilator flaps close automatically, preventing drafts. The flaps reopen automatically as soon as the wind pressure decreases. This ventilation system operates automatically, purely mechanically, and requires no electricity.
