Regel-air Window rebate ventilator FFL Type 21 RF

The Regel-air ventilation system FFL is a self-regulating window rebate ventilator made of plastic for paired installation. It features automatic volume flow limitation. The Regel-air window rebate ventilator FFL 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. With increasing wind pressure, the ventilator flaps of the system close automatically. This prevents draughts. The ventilator flaps open automatically again as soon as the wind pressure decreases. The operation of this ventilation system is automatic, purely mechanical, and requires no electricity.
