- Designed with indented horizontal fins
- Heavy-gauge steel optional volume adjustment damper (SOBD) is operable from the face of the grille
- Available in 1" increments of width and height
Product Application
Our GMR grilles offer versatility in design and function. The sturdy R-core is equipped
with deflected blades that effectively mask the openings on high or low sidewalls. These
grilles also feature an open fin design that provides a large free area—of 86.6%—which
minimizes intake velocity and reduces inlet pressure loss. This ensures that the grilles
have a noiseless operation during peak hours as well. If you are looking for a grille
that is highly effective even during rigorous usage, your search ends here.
Benefits
