What is a Variable Air Volume Box?

A Variable Air Volume (VAV) Box is an HVAC component that controls the amount of conditioned air supplied to a specific zone in a building. Unlike constant air volume systems, VAV systems adjust airflow based on the demand of individual spaces.

Key Functions of VAV Boxes:

• Regulate temperature efficiently in different zones
• Reduce energy consumption by modulating airflow
• Maintain optimal indoor air quality

VAV boxes can be equipped with sensors, dampers, and controllers to adapt to real-time conditions. This flexibility is particularly crucial in large commercial buildings, hospitals, and educational institutions.
