Regel-air ® FFLHmax – window rebate vent for wood and wood-aluminium window s

The FFLHmax is a self-regulating window rebate vent and the systematic further development of the FFLH Type 24. The new version utilises the recognised flap technology, which has proven itself over the last 20 years and reacts to wind pressure. Installation is carried out as usual. The ventilation ducts are visible and even easier to clean.

The vents has been successfully tested by an accredited testing laboratory for air flow, driving rain and noise protection. Not only are air flow rates of over 15 m³/h at 8 Pa achievable, but sound insulation levels of 42 dB can also be attained, depending on the combination and installation configuration.

Regel-air ® window rebate vents FFLHmax are available for timber and timber- aluminium window, catering for a range of applications. The ventilation system is suitable for factory installation in new windows and for retrofitting ( retrofitting) into existing timber and timber- aluminium window.

The flaps in the ventilation modules react to wind pressure in exactly the same way as in the FFL ventilation system and close as wind pressure increases.

The Regel-air ® window rebate vents FFLHmax is available in white, light grey, clay brown and anthracite.
