Grilles & Registers
The open fin design of the GMR R-core With M-frame (removable) minimizes intake velocity, reduces inlet pressure loss, and assures quiet operation. It is designed in a way that helps mask high or low sidewall openings effectively with deflected blades.
- 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.
