FOR INSTALLATION INTO STEPS AND FLOOR AREAS WITH NO FOOT TRAFFIC
Circular and square staircase swirl diffusers
Nominal size 180 mm
Volume flow rate range 10 – 25 l/s or 36 – 90 m³/h
Diffuser face made of sheet steel, powder-coated
For variable and constant volume flows
For false floors and positive pressure plenums
Installation into the risers of steps or into horizontal or sloping floor areas which do not carry foot traffic
High induction results in a rapid reduction of the temperature difference and airflow velocity
Low sound power level due to optimised air distribution inside the diffuser
Optional equipment and accessories
Exposed diffuser face available in RAL CLASSIC colours
Spigot
Cross bar
Application
Type SD staircase swirl diffusers are primarily used as supply air diffusers for comfort conditioning applications
For auditoriums in theatres, cinemas or concert halls
Supply air discharge directly to the occupied zone
Swirling air discharge, either parallel to the installation surface or angled, for mixed flow ventilation
The efficient swirl creates high induction levels, thereby rapidly reducing the temperature difference and airflow velocity (supply air variant)
For variable and constant volume flows
For supply air to room air temperature differences from –6 to +6 K
For false floors and positive pressure plenums
Installation into the risers of steps or into horizontal or sloping floor areas which do not carry foot traffic
Special characteristics
High induction results in a rapid reduction of the temperature difference and airflow velocity
Air discharge either parallel to the installation surface or angled
