Regel-air window rebate ventilator FFL type 34 RF

The Regel-air FFL ventilation system is a self-regulating plastic window rebate ventilator designed for installation in pairs. It features automatic volume flow limitation. The Regel-air FFL window rebate ventilator is installed concealed in the upper, non-fitting area of the window. The ventilation system is invisible from both the inside and outside when the window is closed. As wind pressure increases, the system's vent flaps close automatically. This prevents drafts. The vent flaps open automatically as soon as the wind pressure decreases. The operation of this ventilation system is automatic, purely mechanical, and requires no electricity.
