Auditorium Floor Swirl – Directional

The SMARTEMP Auditorium Floor Swirl Diffuser, type ASF-AD, is a high induction, low air velocity, directional floor swirl diffuser for draught-free air supply with rapid air temperature equalisation from beneath auditorium or lecture theatre seating.
Occupant thermal comfort and indoor air quality are enhanced by the provision of displacement airflow to the low level occupancy microclimate. Heat and contaminants, which rise from occupants as plumes of natural convection, accumulate in a high level stratified layer where they are removed from the space in concentrated form. Occupants are enveloped in a cocoon of high indoor air quality and enhanced thermal comfort.
