Hinged Fixed-Blade Air Grille provides rear access through a fixed louvered face. It suits return-air openings where maintenance access matters more than changing the direction of the front blades.
FEATURES AND BENEFITS
How it helps
Fixed blade row
The discharge geometry remains unchanged when the face is opened and closed.
Optional filter holder
A rear holder can place an accessible return filter behind the grille.
APPLICATIONS
Where it is used
Accessible return openings
Reach a return-air filter or duct entrance from the room side during planned service.
SELECTION GUIDANCE
Choosing the configuration
Clear opening
Allow enough face swing and hand clearance to remove the rear filter without disturbing the surrounding wall finish.
