Blauberg DWP2 125
- Technical data
A swirl diffuser balances air parameters throughout the entire space of the treated room by forming vortex air flow.
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.

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.
Noise characteristics are calculated using the indices given below.

INDEX FOR DUCT SOUND POWER ABSORPTION BY DIFFUSER
|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
