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 ≈ 1.48 K — comfortable.

Description and manufacturing
Purpose
SD diffusers are used in supply and exhaust ventilation and in all types of air conditioning systems. They are designed for installation in walls and suspended ceilings and offer an excellent appearance. They can be used for both air supply and extract.
Design and materials
The product consists of a high-quality aluminium housing with horizontal slots; depending on the model, the number of slots ranges from 1 to 6.
The louvres in the frame are movable and rotatable, allowing the air direction in the room to be adjusted. Several elements can be joined together, so they can be installed in continuous lines of almost any length and shape.
The diffusers are finished with a protective and decorative powder coating. The standard colour is white (RAL-9016), but at the Customer's request the housing and blades can be painted in different RAL colours.
Manufacturing
The series includes both standard sizes and custom lengths L in the range of 300 to 3000 mm in 5 mm increments.
The H dimension is fixed.
SD-1 - h = 50 mm – a single-slot diffuser has a connection height of 50 mm; each additional slot adds 40 mm.
