RAL: Other colors based on RAL specifications.

Fixing Systems and Accessories
The grilles can be fixed with screws. Additional accessories include the PLRG open part with a circular neck and the CG mounting frame, both constructed from galvanized steel.

Performance and Specifications
The document provides detailed specifications on air flow measurement, recommended velocity, pressure loss, and sound power levels. Key formulas include:

Q (m³/h) = Vf_med (m/s) * A_free (m²) * 3600
Q (l/s) = Vf_med (m/s) * A_free (m²) * 1000

Recommended velocity ranges and pressure loss data are provided for different grille configurations.

Conclusion
The CRG series grilles offer versatile solutions for HVAC applications, with various models and configurations to suit different installation needs. The document provides comprehensive technical data to guide selection and installation.
