The Ventüer VL-77EX is designed specifically for exhaust situations and provides a low pressure drop allowing maximum airflow with minimum mechanical assistance. It has a low rain defence effectiveness, however this is not typically an issue in exhaust scenarios.
The VL-77EX comes with flanged and channel perimeter frame options, which can be fixed in to a wide range of primary support structures and cladding types including profiled metal cladding, fibre cement sheet, window joinery systems and others.
The Ventüer VL-77EX can be fitted with a sealed solid backing panel to provide a water-tight rainscreen in areas where the louvres are "inactive", or not required for air flow. It can also be fitted with bird or insect mesh, and can be coupled with the Ventüer range of air control and fire dampers.
