Airflow Technology

Along with the TNO wind tunnel facility at Apeldoorn in the Netherlands, Biddle have successfully developed a patented rectifier, which minimises turbulence in the discharge airstream. With reduced turbulence, induction of the surrounding air is also reduced, which in turn, increases the jet throw by 30-40% of an equal volume/velocity unit. The pressure chamber behind the rectifier evenly distributes the air stream across the whole width of the unit. The result is a deeply penetrating, laminar airstream, reducing energy consumption whilst increasing comfort levels.
