Perforated Air Grille covers a ventilation aperture with a flat panel of regularly spaced holes. The face distributes the open area across the panel and conceals the larger opening behind it, giving room outlets a simple cleanable surface.
FEATURES AND BENEFITS
How it helps
Matched rear connection
The face can connect to an opening or plenum, with a separate rear damper where air quantity needs balancing.
APPLICATIONS
Where it is used
Room supply or return faces
Use where the designed outlet arrangement calls for a perforated panel rather than directional blades.
SELECTION GUIDANCE
Choosing the configuration
Face and free area
Select the hole pattern and opening area for the airflow and noise duty; the overall panel width alone does not define the usable air passage.
