The ceiling diffuser is a supply or return air diffuser made from an Engineering Polymer. It has a simple, visually appealing style that is suitable in commercial and domestic buildings alike. The central diffusion cone of that can be adjusted up or down by hand to control the air volume being supplied. For “shut off” the cone can be adjusted fully home to stop the air supply completely.
The radial supply air pattern of that creates a strong ceiling effect resulting in a draft-less environment. The strong ceiling effect allows it to be used in Variable Air Volume applications.
X – Throw in metres correspond to a terminal velocity in occupied zone of 0.25m/s
Pressure ( Pt ) – All pressures are in Pa (N/m2)
NR – Noise level index in dB based on a room absorption and one diffuser
