TWS Twister Swirl Diffuser

Advanced Air’s range of high-performance Twister Swirl Diffusers (TWS) have been designed to deliver the high air change rates required to meet the demand of high loads. The circular pattern of the deflection vanes, creates an effective swirl motion that has excellent entrainment and provides the highest level of occupancy comfort.

Tech Specs

Construction: All units are constructed from steel with PVC components and are available with a matching range of top or side entry plenum boxes. Volume control can be achieved with a damper mounted within the plenum inlet spigot.

Range & Air Patterns: Swirl diffusers are available in five standard ceiling module sizes (300, 400, 500, and 600) as per dimensional table. Custom sizes are also available. The blades have been designed so they can be removed and reset in the opposite position. This allows the air pattern to be changed, for example, if the diffuser is positioned close to a wall.

Plenum Boxes: The plenum boxes for supply diffusers are supplied with a perforated plate to ensure an even airflow across the diffuser blades. There is the option of top entry or side entry spigots, which can be supplied with an optional volume control damper with a hand-locking quadrant or cord operated that can be adjusted through the diffuser blades.

Finish: The standard diffuser finish is Polyester Powder White RAL 9010 semi-gloss with matt black deflection blades. Other panel colours are available on request, as well as the option of white deflection blades.

Performance: The tabulated performance data for each listed size of diffuser is based on cooling and heating applications. Pressure drop is stated in Pascal’s (N/m2). Throws stated are to a terminal velocity of 0.5m/s and used as a maximum value will give a velocity of less than 0.25m/s within the occupied space. Noise levels are based on the peak values on NR curves.
