o Designed for noise level reduction on the air ducts in ventilation and air-conditioning installations.
o Combustibility – class 0
o The data is in accordance with EN 7235
o Corpus of galvanized metal sheets with incorporated baffles placed parallel to the air flow.
o Baffles are made of plates of fiber-glass, wrapped in glass material to prevent atomization, protected by a safety metal grid and frame of galvanized metal sheets.
• Flat baffle sound attenuator modifications
o DSA 10/10 – baffles with thickness D=100 mm and distance between baffles S=100 mm – effective middle range frequency - from 500 to 4000 Hz. Sound attenuators are designed as standard elements for in-line systems.
o DSA 10/6 - baffles with thickness D=100 mm and distance between baffles S=60 mm – effective high range frequency.
o DSA 20/12 - baffles with thickness D=200 mm and distance between baffles S=120 mm – effective low range frequency.
o Construction allows incorporation in air-duct system or ventilation equipment with rectangular shape with flange type connectors (Europrofile).
