DECIBEL AL® 300 and DECIBEL AL® 600 are a single louver attenuating system. The louvers are made of steel sheets, filled with sound-absorbing material, and one-sided cover by a perforated metal sheet.

The standard sizes of the box are 12'' х 40'' х 40''. or 24'' х 40'' х 40''. This makes the attenuators easy to install on facade openings or hang on support metal construction. They can also be stored as standalone screen wall attenuators. DECIBEL AL® 300 and DECIBEL AL® 600 are used mainly in engine rooms, ventilation openings, power generator rooms, boiler rooms, cooling towers, or any other industrial or HVAC systems.

DECIBEL AL® is made of galvanized or powder-coated metal frame and modular parts, including sound-insulating and sound-absorbing front panels. The wings are made of galvanized sheet metal with a finish of perforated sheet metal and filling of sound-absorbing material.

 

DECIBEL AL® sound-insulating louvers are specially produced  for  use in cases where a large amount of air must pass  through  a  louvre  and  where  the  installation space  is  limited. This includes enclosures, generators and cooling / heating systems. 

Two standard sizes of DECIBEL AL® (12'' and 24'') soundproofing louvers are produced, each with its own properties in terms of air flow, sound insulation and installation depth. DECIBEL AL® can also be produced in non-standard sizes.
