Floor Diffusers Type SD

The Type SD  is a Circular and square staircase swirl diffuser.

Features

• 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
• Excellent air quality since the supply air is discharged directly to the occupied zone
• Installation into the risers of steps and into floor areas which do not carry foot traffic

Nominal sizes

• 180
