In line fans
Inline fans mount directly in the ventilation duct run, integrating invisibly into the installation. An intermediate solution between axial and centrifugal fans: more compact, better pressure than axial wall fans and lower noise levels. Ideal for residential duct installations of 2-5 metres, small offices and as boosters on existing duct runs that no longer deliver the required airflow.
