The dimension of directional diffusers from the SI device is 595x595mm. If you put an Imperial unit directional diffuser (603x603mm) on the SI unit ceiling, it will never match. The exact same applies to other sq.-shaped ceiling diffusers.
We begin sizing from the main principal duct which is segment A. To limit the noise Within this part we’ll specify that it could have only a greatest velocity of 5m/s.
