Swirl face

1.2 mm or 1.5 mm thick aluminum sheet.

• The frame and blades are made from high quality extruded aluminum profiled construction with Powder coated color finish.
• Supply swirl diffuser and return swirl diffuser can be supplied with volume damper to control static pressure and the air volume flow rate: installed in plenum box.
• Square steel swirl diffuser with adjustable radial air pattern is used for the supply of cooled or heated air.
• In facilities such as offices, shopping centers, schools, diffusers for        ceiling or exposed duct mounting.
• The square diffuser offered. complete with a plenum box with side – or top connection.
• This diffuser can also be used for exhaust.
• The diffuser is equipped with adjustable PVC deflectors creating the possibility to obtain an external or internal swirl.
• A high induction is obtained by the exceptional swirl discharge which makes them extremely suitable for VAV terminal boxes.
• Foam gasket is sealed around the back of the frame as option to avoid air leakage.
• Powder coated color finish per RAL color codes as standard and         flexibility of finish.

• Ceiling swirl diffuser in air conditioning system 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. Ceiling swirl diffuser allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.
• Type SWA ceiling swirl diffusers have adjustable air control blades.
  The air pattern can be adjusted to meet different local requirements. Horizontal air discharge is one – way, two – way or Omni directional. Vertical air discharge is possible but only for heating.
  The supply air to room air temperature difference may range from -12 to+10 k.
• A damper blade (optional) simplifies volume flow rate balancing for commissioning. Pressure tap and cord-operated damper blade (optional) allow for volume flow rate balancing with the diffuser face in place.
• To give rooms an aesthetic, uniform look, type SWA diffuser may also be used for extract air. Air control blades are not required for extract air applications.

• Module size 600 × 600 mm & plenum neck size 250 dia.
• Neck velocity is measured in m/sec.
• Ps: static pressure loss across the diffuser in mm of H2O.
• Throw (meters) is measured for a terminal velocities of 0.25, 0.5 & 0.75 m/sec.
• Noise criteria (NC) based on a room attenuation of 10 db.
