Hi all, I'm in the process of servicing an AHU system as part of a building refurb that our company is doing. Does anyone know roughly the free air area of a 600x600 4 way supply diffuser? You know the sort, aluminium painted white, that sits in t-bar ceiling grid.
I need this to apply to my anemometer m/s readings to give client the volumes.
I know they will vary by manufacturer but a ball park figure will help a lot.
Thanks
