The DucoBox Focus is an extraction unit that provides zonal extraction within Duco’s Demand‐Controlled Natural Ventilation Systems (DCNVS).
The DucoBox Focus is both the driver of the system and the master unit to which control components can be paired. This quiet, compact, durable and extremely energy‐efficient extractor fan extracts moist and/or stale air as required and at the correct rate.
Integrated control valves (which can be ordered separately) also ensure that air is extracted only where needed, resulting in quieter and energy‐efficient operation. Simple design and an efficient DC motor ensure long service life.
