NEW www.stavoklima.eu acoustic louvres PHZe New modelS: 200, 300, 400, 600 mm of depth description and use: bird protection grid in detail: Acoustic louvres "PHZE" are made of plain galvanized steel or powder coated RAL (stainless steel or AlMg3 available upon reques). The louvres are filled with sound absorbing material covered with perforated metal plate for increased effectivity. There are 4 different depths available according to desired attenuation. 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 an air duct (direct installation or with a frame). Acoustic louvres are used for reduction of the noise comming out from various openings such as from engine rooms or noisy industrial areas. dimensions (standard delivery): „a“ (width) [mm]: 200; 300; 400; 500; 630; 800; 1000; 1250; 1400; 1600; 1800; 2000; 2250; 2500 A+100 C A Bird protection grid A „c“ (depth) [mm]: 200; 300; 400; 600 Other dimensions available on demand.

The louvre has to be calculated with respect to the air flow in the cross section in front of the louvre [AxB dimension], to the desired attenuation value [sound pressure value at the defined point] and to the noise source [sound capacity Lw(a)]. A ŘEZ A-A pcs 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) leVeliNg Screw detail (+frame) filter adaPter eu3 iNSulatioN Izolační nástavec adaPter Filtrační nástavec EU3 50 (á 20 mm) min. 30 mm max. 500 mm iNSulatioN adaPter + wall bracket Izolační nástavec + nástěnná konzola 30 50 BxA BxA BxA BxA CxD 50 50 Detail stavěcího šroubu ( + rámeček) filter adaPter FiltračnímouNted) nástavec nástěnný EU3 (wall eu3 PHZE-KN PHZe -
