Fixed-Blade Air Grille finishes an air opening where the blade direction should remain unchanged. The fixed core gives a consistent louvered face for return air or another opening whose distribution does not need regular directional adjustment.
FEATURES AND BENEFITS
How it helps
Mounting choice
Visible or concealed fixing and a matching subframe allow the face to suit the wall or ceiling detail.
APPLICATIONS
Where it is used
Return-air openings
Cover a room return with a fixed louvered face.
Ventilation refurbishments
Replace a grille where the existing opening already has the required fixed airflow arrangement.
SELECTION GUIDANCE
Choosing the configuration
Flow and direction
Use a separate balancing component when air quantity needs adjustment; fixed front blades do not provide directional tuning.
