Print this pageNoise Attenuation
Blowers, exhausters and pneumatic conveying systems need to be carefully designed to reduce the production of unacceptable sound levels. This noise emanates from several points - the predominate source is the blower rotor pulsations created by the compression of each air pocket as the rotor lobes pass the outlet opening. This noise is then passed along the pipework and radiates from it, however there are also additional noise sources from the motor and friction generated by the conveyed product.
Cost effective design of noise attenuation systems requires a careful assessment of the overall system, location and performance requirements in order to make appropriate component selections.
Nu-Con is able to consider all these factors to provide equipment suitable for the purpose and complying with the required sound level requirements - typical system components include:
- Blower inlet / outlet silencers
- Reactive silencers with expansion chambers/baffles/muffle tubes
- Absorptive silencers with perforated tube and acoustic insulation
- Combination silencers
- Secondary / tertiary slencers
- 3-lobe blowers with internal pulsation cancellation
- Anti-vibration mountings
- Acoustic enclosures with flame retarding insulation and fan cooling
