Bird protectiongrid
Description and use:
Acoustic louvres "PHZE" are made of plain galvanized steel or powder coated RAL (stainless steelor AlMg3 available upon reques). The louvres are lled with sound absorbing material covered with per-forated metal plate for increased effectivity. There are 4 different depths available according to desiredattenuation. The air inlets are equipped with bird protection grids as standard.
Construction angle of the sound absorbing blades allows also the installation as an end piece of anair duct (direct installation or with a frame).
Acoustic louvres are used for reduction of the noise comming out from various openings such as fromengine rooms or noisy industrial areas.
Dimension indicated as "A" and "B" are actually about 30mm smaller than the opening due to easy installation.(Example: For the duct of 1000x800mm acoustic louvres of the following dimensions will be delivered:"A" actual = 970mm, "B" actual = 770mm)

C (depth) [mm]:200; 300; 400; 600
Other dimensions available on demand.
Acoustic parameters and planning:The attenuating capacity of the acoustic louvre can be calculated in thesellection software . The louvre has to be calculated with respectto the air ow in the cross section in front of the louvre [AxB dimension],to the desired attenuation value [sound pressure value at the denedpoint] and to the noise source [sound capacity Lw(a)].
