SWISS ACOUSTIC SOLUTIONS
Circular silencers for monobloc air conditioners
Silentube is the KlimaSilent solution for through-wall ducts on monobloc air conditioners without an outdoor unit. We manufacture removable KS-S162 and KS-S202 acoustic cartridges, subject to an assessment of installation compatibility.

Ø162 and Ø202 refer to the wall opening
The references identify the nominal core-drilled hole diameter. The actual internal duct diameter must be measured separately. A product name or wall opening size alone is therefore not enough to select the cartridge.
Ducts, external grilles and access
Checks cover internal diameter, available length, external grilles and fixings. We also consider insertion from outside on existing installations where technically possible. Innova models are a particular area of attention, without claiming universal or certified compatibility.
Pair pricing and acoustic assessment
Choose Ø162 or Ø202 in the configurator. The indicative pair price appears after submitting the request; compatibility and conditions must be confirmed. Performance figures from silencers for other applications are not attributed to Silentube, and unmeasured dB reductions are not promised.
Frequently asked questions
Does it fit every monobloc air conditioner?
The brand alone does not establish compatibility. Ducts, grilles and installation conditions must be checked.
Is this the same as an outdoor acoustic box?
No. Silentube concerns ducts on monobloc units without an outdoor unit. ClimaBox or HeatBox are considered for outdoor equipment.
Is the price for a single silencer?
No. The Ø162 and Ø202 prices shown after the request are per pair, excluding VAT.
