Regel-air window rebate ventilator FFL Type 20 RF

The Regel-air FFL ventilation system is a self-regulating plastic window rebate ventilator designed for paired installation. It features an automatic volume flow limiter. The Regel-air FFL window rebate ventilator is installed concealed in the upper, fitting-free area of the window. The ventilation system is not visible from either the inside or the outside when the window is closed. As wind pressure increases, the system's vent flaps close automatically, preventing drafts. The vent flaps open automatically as soon as the wind pressure subsides. This ventilation system operates automatically and purely mechanically, requiring no electricity.
