Ventilation grilles are airflow control components that regulate air intake and exhaust in industrial ventilation systems while preventing debris entry.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Free Area | 40-85% | |
| Blade Spacing | 10-50 mm | |
| Pressure Drop | 5-50 Pa | |
| Frame Thickness | 1-3 mm | |
| Noise Reduction | Up to 15 dB(A) | |
| Temperature Range | -40°C to 120°C | |
| Air Velocity Range | 1-10 m/s |

Supply grilles are designed for air distribution into spaces with directional blades, while return grilles focus on air extraction with simpler designs. Supply grilles often have adjustable blades for airflow direction control, while return grilles prioritize free area for efficient air collection.
Grille size is determined by airflow rate (CFM or m³/h) divided by face velocity (typically 500-800 fpm or 2.5-4 m/s). Consider free area percentage, pressure drop limitations, and noise criteria. Always consult ventilation system specifications and follow ASHRAE guidelines for proper sizing.
Regular inspection for debris accumulation, cleaning of blades and frames, checking for corrosion or damage, verifying blade alignment, and ensuring proper sealing. Frequency depends on environmental conditions but typically ranges from quarterly to annual maintenance.
