DISPLATEK ADU4

Specification:DISPLATEK ADU04 is a rectangular air distribution unit for displacement ventilla-tion. The armature has a rectangular duct connection with sleeve dimensions.The unit is fitted with diffusion nozzles which make it possible to change the geometry of the near zone.Th eunit is maintenance free and there is no risk of clogging.

Materials & Finish:Internal and external parts are galvanised steel, nozzles are black plastic and face plate 1.5mm galvanised steel. Standard finish is RAL9010 white powder coat, other colours being available on request.

Mounting:Floor mounting against wall.Duct connection from above or below.

a0,2 is the horizontal distance from the wall to where the maximum velocity has de-creased to 0.2m/s.b0,2 is the horizontal distance from the cen-tre of the unit parallel with the wall to where the maximum velocity has decreased to 0.2m/s.

Sound Pressure Level LA,dB(A)The sound pressure level is specified at room damping of 4dB, corresponding to the damping in a room with a room constant of 10m2 SABINE measured in the reverbera-tion field.

Example of Calculation:Air flow: 150l/s (540 m3/h)Size 2510 lies within the recommended field of application.

Near zone at -3K: a0,2 = 1,2m, b0,2 = 4,0m.Pressure loss: Pt = 16PaSound pressure level: LA = 24 dB(A)

Sound Power LevelSound Power Level LW(dB) = LA + KOK

Sound AttenuationSound attenuation L (dB) including end reflection
