Choosing the right plenum box

The role of a plenum box in regulating air and sound in your ventilation system is crucial for comfort and indoor air quality. It ensures measured and balanced airflow, evenly distributes air to diffusers, and secures good sound attenuation.

To maximize the effectiveness of your air diffuser, it's important to pair it with the right plenum box. Choose wisely, as the right pair can significantly enhance comfort, indoor air quality and energy efficiency.
