Airflow CAV and VAV regulators are used to automatically regulate the airflow in the ventilation system. The task of the airflow regulators is to maintain the required airflow rates, allowing to set the optimal climate conditions for each room in the building. The airflow can be regulated both in the supply and exhaust ducts.

Types of airflow regulators:

• constant flow regulators with a fixed set point,
• air flow regulators with switching between two preset values (V ̇min, V ̇max,),
• constant air flow regulators with variable airflow setting,
• VAV variable air flow regulators.
