Splitter sound
Plate silencers with anti-resonance panels ARS, designed for use in air conditioning and ventilation systems, directly to reduce noise levels due to the effective prevention of resonance (including in the low-frequency range)
ARS Features
- High energy efficiency thanks to aerodynamically optimized frame profile (radius > 15 mm)
- Acoustic performance measured according to ISO 7235
- The sound-absorbing material is biosoluble and therefore hygienically safe
- Sound-absorbing material covered with fiberglass for protection against erosion
- Non-flammable sound-absorbing material meets fire resistance class A1 (according to the requirements of EN 13501)
ARS silencers are available in standard and custom sizes for use in zones 1 and 2, as well as zones 21 and 22, in accordance with EU Directive 94/9/EC. Operating temperature up to 100°C.
Additional equipment and accessories
- Additional perforated metal plate to protect the sound-absorbing material
- Powder coating
- Stainless steel
- Aluminum alloy (AlMg3) construction, resistant to salt water
Filling Features
ARS plate silencers from AIRNAMICA include noise-absorbing plates. These plates attenuate noise through absorption and resonance effects. The sound-absorbing material of the plates is mineral wool. The part of the plate surface parallel to the air flow is covered with resonating panels. These panels vibrate (resonate) when exposed to sound, absorbing sound energy.
The greatest resonance occurs at the critical frequency of the fan noise. This provides more intense and broadband noise reduction than plates using only absorption.
