Stiebel Eltron 233013 silencer LWF SR 160 - 1

Silencer consisting of a rectangular outer casing, a perforated inner tube and two connection ends with rolling ring seal. The space between them is filled with sound-absorbing insulation material. A glass fleece between the inner tube and the insulation prevents the insulation material from coming into contact with the air flow. The rectangular shape achieves particularly high attenuation in the lower frequency range.
