NVAV Series VAV Units
VAV Pressure Indepent Control
Nenutec Variable Air Volume (VAV) Terminal Units are volume flow rate controller for supply air on variable air volume system. These units are designed to control the airflow rate of conditioned air into an occupied space in response to a control signal from thermostat or Building Automation System (BAS). They could be used in stand alone system or interfaced with Modbus or BACnet.
