Wall Louver – Adjustable

An adjustable wall louver is an air intake or exhaust device composed of multiple movable blades. When mounted in an opening, the louver allows controllable airflow with minimal pressure drop while also protecting against rain and debris.

PRODUCT BENEFITS

• Provides cool, fresh air intake for the building.
• Adjustable blades can be closed to shut off airflow into building.
• Blade position can be adjusted at various angles to control airflow and modulate the percentage of open area.
• Optional actuator automates opening and closing of the blades.
• 90-degree adjustable blade models maximize airflow, allowing fewer individual louvers to be required for smaller spaces.
