Regel-air window rebate vent FFL Type 21 RF Set

The Regel-air ventilation system FFL is a self-regulating plastic window rebate vent for paired installation. It features automatic volume flow limitation. The Regel-air window rebate vent FFL is installed concealed in the upper, condensation-free area of the windows. When the window is closed, the ventilation system is not visible from either the inside or the outside. When wind pressure increases, the vent flaps of the system close automatically, preventing drafts. The vent flaps open automatically again as soon as the wind pressure decreases. This ventilation system works automatically, is purely mechanical, and requires no electricity.
