Natural roof ventilation
Size: 110, 140, 170, 200
The WINDCATCHER X-Air is a 2nd generation natural ventilation system featuring the patented ACTIVLOUVRE® modulating aerofoil louvre technology. The system consist of an external static louvre and internal active louvre arrangement, which varies the opening and free area through the louvre face. The variable louvres can provide maximum ventilation rates when fully open or modulated to increase louvre pressure or closed to prevent the ingress of precipitation.
In addition to the ACTIVLOUVRE arrangement, the system also incorporates external air catchment fins to provide greater area at the louvre improving performance in relation to wind speed. Pressure release vanes at the fins provide a means to reduce face pressure under high winds. The systems can also be specified to include solar powered architectural lighting
