Regel-air Window rebate ventilator FFL Type 20 RF Set

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 FFL window rebate ventilator is installed concealed in the upper, hardware-free area of the windows. When the window is closed, the ventilation system is not visible from either the inside or the outside. As wind pressure increases, the ventilation flaps of the system close automatically, thus preventing drafts. The ventilation 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.
