The basic unit of this type of terminal includes damper and flow sensor and can be equipped with different control equipment according to the user. These terminals adjust the volume of air needed in the room according to the feedback received from the thermostat inside the room.

The basic unit of single duct round terminals (Single Duct VAV Box) variable air volume includes damper and flow sensor and can be equipped with different control equipment according to the user. These terminals adjust the required air volume of the space according to the feedback they get from the thermostat inside the room. These terminals are able to deliver hot and cold air to the space at the same time. In the conditions that such terminals are used to control hot and cold air, a dual-function thermostat and an air temperature sensor must be used at the entrance, as well as controls for changing the system from cooling to heating and vice versa. Usually, types of air distribution terminals are used in the interior spaces of buildings that have a constant cooling load and do not need heating.
