Resonance, as well as airflow, can cause unpleasant noise. This is prevented by the dampers that we supply in a circular design with a standard width of TH 50 (50 mm) and TH 100 (100 mm).
Our customers most often use dampers for buildings in a development requiring low noise levels, typically (for example in) exhausts from restaurants, guest houses or clubs.
Increasingly, customers wanting to ensure minimal noise from their HVAC units are also installing dampers immediately behind the unit.
We produce the outer shell of the damper from galvanised material, and the inner shell is perforated. The damping layer is mineral wool with non-woven fabric. The maximum operating temperature of the damper is +80 °C, and the standard length is 900 mm. The high operating temperature range allows installation in hot air distribution systems.
