Test Method

The analysis of the aeraulic performances of the KQ2 series diffusers have been carried out by means of a “virtual test laboratory”.

All the tests and the relative measurements have been conducted by means of an advanced CFD (Computational Fluid Dynamics) software.
This applies the method of the finished elements to the fluid dynamic for the analysis of speeds, air flow distribution and pressures losses.

The KQ2 Series units are squared diffusers with slots on panel. The slots are spiral-shape drawn up and they have orientable deflectors. They are used both in supply and extraction and they are ceiling installed.They find their application where is required a cared for design and where is appreciated an easy installation and regulation of the throw.
