DucoBox Silent Connect 400 m³/h - plug type G

The DucoBox Silent Connect is an extraction fan that provides central extraction within Mechanical Ventilation - System C units. The unit can be used up to 400 m3/h at 150Pa for demand controlled domestic applications with an easy programming.

This very quiet, compact, durable and extremely energy-efficient extractor fan removes moist and/or polluted air when needed and in the right quantity. Simple design and an efficient DC motor ensure long service life.

DucoBox, with a minimum sound power of 57.5 dB(A) at intake and 46.5 dB(A) at radiation from the cabinet, is the quietest in Europe and works whisper-quietly thanks to the double wall, in combination with an acoustic base plate. In addition, the Silent Plus package provides additional acoustic damping of up to 3 dB! DucoBox has 1 discharge and 7 suction connections as standard (diameter 125 mm).

All communication is completely wireless. The network can be set up quickly & easily thanks to the in-house developed communication protocol. With this unit, you can also combine the unit with box sensors (internal plug-in sensors in the box itself) or room sensors, both based on CO2 and/or moisture measurements.
