Regel-air® ventilation system FFL-smart – for flexible air flow rates

The Regel-air® FFL-smart is a self-regulating window rebate vent that is milled into the sash overlap of the PVC window. The integrated return and damping spring ensures silent and gentle closing of the damper and, in special cases (e.g. arched windows or narrow windows), also allows for vertical installation.

The use of the FFL-smart ensures controlled dehumidification without draughts and prevents mould damage. Thanks to its excellent air flow rates and sound insulation properties, it is also suitable for demanding applications.

Maximum flexibility in production

The FFL-smart has been specially developed to meet the demands of modern window production with maximum efficiency. It fits into any standard PVC window and can be seamlessly integrated into existing processes.
The FFL-smart process video demonstrates how easily the vent can be incorporated into window production on the machining centre.
