FEATURES  

A swirl diffuser balances air parameters throughout the entire space of the treated room by forming vortex air flow.

DESIGN  

The units are made from steel and powder-coated. Angled blades provide high ejector capability.

Specially designed casing with additional side slots for horizontal discharge. Ceiling-mounted with direct air duct connection.

TECHNICAL DATA

AIR JET DISTRIBUTION GEOMETRY

The diffuser is shaped to create a bi-directional air jet: the side slots ensure horizontal air discharge while the internal blades fixed at 30-35° (depending on the model) form a vortex air jet in the vertical plane.

  • 0.2 hor. is the maximum range of the air jet in the horizontal plane to the point at which the air jet velocity is 0.2 m/s. 
  • 0.2 vert. is the maximum range of the air jet in the vertical plane to the point at which the air jet velocity is 0.2 m/s. 
NOISE CHARACTERISTICS  

Noise characteristics are calculated using the indices given below.

NON-ISOMETRIC AIR FLOWS

The value given in the catalogue are true for isothermal jets – i.e. when the jet temperature equals the temperature in the room. Any difference in the jet temperature and room temperature affects the jet geometry. During cold air supply the jet is deflected downwards with a reduction in length. During warm air supply the jet is deflected upwards with an increase in length.

I'0,2= I0,2 * KI0,2

KI0.2hor. is the index of horizontal jet length change
KI0.2vert. is the index of vertical jet length change
