Multi-zone valve DucoBox Energy (without sensor) Ø125 is a compact, mechanical ventilation accessory that allows the home ventilation system to be divided into zones and controlled separately.

Diameter: 125 mm (Ø125), which refers to the size of the air duct.

Design without sensor: The valve does not contain a built-in sensor, so it is controlled by external devices (e.g. timer, manual switch or central control unit).

Zone control: Each zone has a separate valve, so ventilation only happens where it is needed - this results in energy savings and quieter operation.

Compact size: Height: 150 mm, Width: 192 mm, Depth: 138 mm - can be easily installed even in narrow spaces.

Application: In residential ventilation systems, especially in places where air supply divided into zones is important (e.g. multi-storey buildings, separate living quarters).
