Abstract (en)

An air delivery system comprises a fan within a housing, an air entry port to the housing and an air exit port from the housing. The air exit port has an air exit area, and this area can be selectively blocked such that the air treatment system is configurable between a relatively high flow velocity air delivery from a relatively small air exit area and a relatively low flow velocity air delivery from a relatively large air exit area. The system is thus configurable into different air flow modes for different air treatment functions.
