SPLITTER SOUND ATTENUATOR WITH HIGH INSERTION LOSS, EVEN IN THE LOW-FREQUENCY RANGE
Splitter sound attenuator, basically a duct section with integral splitters (type MK) with resonating panels, for ventilation and air conditioning systems
- Attenuation effect due to absorption and resonance
- Energy efficient due to aerodynamically formed frame (bullnose radius 20 mm)
- Sound absorbing material is biosoluble and hence hygienically safe
- Sound absorbing material faced with glass fibre fabric as a protection against erosion due to airflow velocities up to 20 m/s
- The sound absorbing material is non-combustible, to EN 13501, fire rating class A1
- Leakage class C and pressure class 2 according to EN 15727
- For use in areas with potentially explosive atmospheres (according to EC Directive 2014/34/EU (ATEX)), zones 1, 2, and zones 21 and 22 (outside) according to EC Directive 1999/92/EC
- Operating temperature up to 100 °C, with expanded metal (variant L) up to 300 °C for a limited period of time
Optional equipment and accessories
- Expanded metal as an additional mechanical protection for the sound absorbing material
- Stainless steel variant A2 (1.4301), with optional perforated metal facing as an additional protection for the sound absorbing material
- Other stainless steel and aluminium variants as well as PUR coating are upon request
