Floor Diffusers Type SDRF

Features

• Various nominal sizes with 1 – 6 outlets
• Volume flow rate range 2 – 25 l/s or 7 – 90 m³/h
• Diffuser face made of sheet steel, powder-coated
• For variable and constant volume flows
• For false floors designed as positive pressure plenums
• Installation into the risers of steps
• Visible screw fixing
• 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
• Spring clip fixing (concealed)

Application

• Type SDRF 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 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 designed as positive pressure plenums
• Installation into the risers of steps

Special characteristics

• High induction results in a rapid reduction of the temperature difference and airflow velocity
• Air discharge parallel to the installation surface
• Excellent air quality since the supply air is discharged directly to the occupied zone
• Vertical installation into steps

Nominal sizes

• No. of outlets: 1, 2, 3, 4, 5, 6
