What percentage of free air space do metal air grills have?

• A. 50%
• B. 60%
• C. 75%
• D. 80%

Answer: (C)

Metal air grills typically have 75% free air space. This percentage indicates the portion of the grill that allows air to pass through unobstructed. High levels of free air space are essential for ensuring efficient airflow in HVAC systems. They help minimize resistance and maximize air circulation, which is crucial for maintaining proper ventilation and indoor air quality. Understanding the design and specifications of air grills is vital for professionals in the HVAC field, as it impacts the overall efficiency of heating and cooling systems. This knowledge enables technicians to select the appropriate grills based on the requirements of the system they are working on.
