Regel-air window rebate ventilator FFL Type 34 RF Set

The Regel-air FFL ventilation system is a self-regulating window rebate ventilator made of plastic for paired installation. It features automatic volumetric flow limitation. The Regel-air FFL window rebate ventilator is installed concealed in the upper, fitting-free area of the windows. When the window is closed, the ventilation system is not visible from either inside or outside. As wind pressure increases, the system's ventilator flaps close automatically, preventing drafts. The ventilator flaps reopen automatically as soon as the wind pressure decreases. The operation of this ventilation system is automatic, purely mechanical, and requires no electricity.
