Regel-air window rebate ventilator FFL-Uni Type 88

The Regel-air® FFL-uni is a self-regulating window rebate ventilator, ideally suited for retrofitting onto existing windows. Factory installation is also possible. The FFL-uni fits almost all windows and window types (with the exception of flush-mounted windows). The window rebate ventilator features two self-regulating flaps that control the volume flow depending on wind pressure to prevent drafts. The Regel-air® FFL-uni is screwed onto the upper frame using a drilling and cutting template. The use of the FFL-uni allows for controlled air exchange and reliable dehumidification without drafts.
