Circular air diffuser SD

squarefixedinduction

Circular and square staircase swirl diffusers Nominal size 180 mm 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 Exposed diffuser face available in RAL CLASSIC colours Spigot Cross bar 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 SD staircase swirl diffusers have fixed blades. Different attachments are available to influence the air pattern and adapt it to local requirements. A spigot can be used to achieve air discharge parallel to the installation surface, while a cross bar can be used to achieve angled air discharge. The air pattern should be such that the air does not blow onto the feet of people sitting near the diffuser. If staircase swirl diffusers are placed underneath seats or vertically in the steps between seats, angled air discharge is recommended. If diffusers are placed in the steps below the seats, parallel air discharge is recommended.
