ESRS Rectangular silencers with sound-absorbing splitters
Description
Rectangular silencer with sound-absorbing splitters to control noise in air conditioning, heating and ventilation systems. The splitters, with an aerodynamic profile at the inlet and outlet, allow low pressure drops with excellent attenuation performances.
Characteristics
External structure: 0.8 m thick galvanised steel frame, 30 mm flange for lengths up to 6 m, 40 mm flange for longer lengths. Splitters: sound-absorbing splitters with 0.8 m thick galvanised steel frame, 50 kg/m³ density rock wool with anti-flaking surface and and micro-extended mesh.
