The standard version of the central extract unit with acoustic attenuation, without valve control. Moreover, with this type, you can choose between CO2 or Humidity Boxsensors (internal pluggable sensors in the box itself), and CO2 or Humidity Sensors.
In addition, this new powerful central extract unit, the DucoBox Silent, has been raised to a higher level by the development team at Duco, managed entirely in-house. All communication takes place completely wireless. The network can be built up quickly and easily thanks to the communication protocol we have developed. The DucoBox Silent is applicable in the Duco CO2 System and the Duco Comfort System.
When developing the central extract unit, Duco paid a great deal of attention to acoustic performance. We can proudly claim that the DucoBox, with a minimum noise level of 57.5 dB(A) when extracting and 46.5 dB(A) emission from the housing, is the quietest in Europe and operates silently thanks to its double wall in combination with an acoustic baseplate. Moreover, the Silent Plus Kit delivers additional acoustic attenuation of up to 3 dB! The DucoBox features seven (125 mm diameter) connections as standard.
