The units are of galvanised steel sheet construction with aluminium sections and include an air equalising plate (painted in black) inside, as well as static pressure measurement to obtain the supply flow rate. The standard finish is RAL 9010 white paint, although any RAL colour is available upon request.
The S-90-44 version has a larger free air outlet área tan the standard S-90 diffuser to provide an outlet velocity reduction of 35%.
