The dimension of directional diffusers within the SI device is 595x595mm. If you put an Imperial unit directional diffuser (603x603mm) over a SI unit ceiling, it will likely not suit. The same applies to other sq.-formed ceiling diffusers.
The sharp turns cause a large amount of recirculation areas in the ducts, preventing the air from relocating efficiently.
50cm x150m duct, 45degx150mm, 50cm duct, 45degx150mm, 100mm reducer linked directly to the 19cm 100mm pipe with the wall with a 100mm 45deg temperature include outlet in the light shaft.
You can do your own figures if you would like obtain a ballpark notion of what you need, but it really’s ideal not to rely only on your own figures.
