Sound attenuator splitters, installation kit to be used in ventilation and air conditioning systems

• Attenuation effect due to absorption

• Energy efficient due to aerodynamically formed frame
  (bullnose radius 20 mm)

• Acoustic data measured to ISO 7235

• 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

• 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 upon request

• U-sheets and clamp sheets to join subdivided attenuator splitters
