CK SERIES
Round muffler with sound-absorbing splitter for increased insertion loss.
Aerodynamic splitter provides increased insertion loss
Choice of different splitter thicknesses ensures the best application
Weakening effect due to absorption
The sound-absorbing material is non-flammable mineral wool and is harmless to health in accordance with the German TRGS 905 (Technical Regulations for Hazardous Substances) and EU Directive 97/69/EC
Acoustic data measured according to ISO 7235
Leakage class C or D (depending on size) according to EN 15727
For use in areas with potentially explosive atmospheres (according to EU Directive 2014/34/EU (ATEX)), zones 1, 2 and zones 21 and 22 (outdoor) according to EU Directive 1999/92/EC
Installation
Round muffler for reduced noise
To reduce fan noise
Can be used as a crosstalk suppressor to reduce noise transmission through ductwork between adjacent rooms.
Peculiarities
Insertion loss measured according to ISO 7235.
Choice of two divider widths for each nominal diameter.
Increased insertion loss due to wider splitter
Reduced pressure drop due to smaller divider
The sound-absorbing material is non-flammable.
