The VLD and VLV diffusers have been specially designed for industrial applications. They are made of steel and aluminum and are equipped with adjustable air guide blades that allow the air jet to be directed from horizontal to vertical without affecting the airflow balance.
The blades can be adjusted manually using cables or motorized. When the blades are closed, the VLD achieves maximum throw in cooling mode thanks to its large-perforated wall.
In the same position, the VLV generates a short-throw horizontal airflow due to its perforated steel wall. The VLV can create a decontaminated air zone.
