Performance
Section through the room at the diffuser. Velocity and temperature on the jet axis come from the calculation verified against the manufacturer's selection software; the surrounding field is an engineering model of the jet and return flow, not a full CFD analysis. Lines show air particle paths.
Temperature difference in the occupied zone ≈ 0.78 K — comfortable.

Description and manufacturing
Purpose
Rotary diffusers with individually adjustable blades are designed for horizontal air distribution, so that the airflow is distributed evenly throughout the room. They are used in supply and exhaust ventilation, air conditioning and air heating systems, in rooms with ceiling heights from 2.6 to 4 metres.
Design and materials
The diffusers are made of galvanised steel in a square design. The adjustable blades can be made of plastic in RAL 9005 (black) or RAL 9016 (white).
In this series, the air discharge direction is set by changing the position of the guide vanes. The swirling flow of supply air at the diffuser outlet achieves a high induction ratio and, as a result, rapid air penetration and equalisation of the airflow temperature with the room temperature.
The panel is coated with heat-resistant powder paint, which provides reliable protection against adverse environmental factors and prevents premature wear of the product.
The standard colour is white, but any other RAL colour is available at the Customer's request.
