Circular air diffuser SDRF

rectangularfixedinduction

Circular and rectangular staircase swirl diffusers Various nominal sizes with 1 – 6 outlets 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 Exposed diffuser face available in RAL CLASSIC colours Spring clip fixing (concealed) Staircase swirl diffusers in air conditioning systems create a swirl to supply air to rooms. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Staircase swirl diffusers supply the air directly to the occupied zone and even to individual room occupants. The result is mixed flow ventilation for comfort zones and an excellent air quality in the occupied zone. Type SDRF staircase swirl diffusers have fixed blades. Air discharge parallel to the installation surface. The supply air to room air temperature difference may range from –6 to +6 K
