Industrial fan noise reduction: an efficient alternative to silencers

Did you know it’s possible to reduce industrial fan noise and to improve fan efficiency using innovative aerodynamic technology instead of silencers? The efficiency gains can often make noise control projects profitable.

Performance and Costs – 80% reduction in capital cost, 20% efficiency improvement*
Typically 10dB – 30dB tonal attenuation at a fraction of the capital cost of conventional silencers and with minimal down-time required for installation.

aerodynamic fan noise reduction - attenuation without silencers

Car and aircraft designers develop aerodynamic aids to enhance performance. We’ve developed similar technology for fan systems to make them as efficient as possible. We model the system and design retro-fit aero-inserts for existing fans to reduce noise at source. Where applicable, it is often possible to dispense with conventional silencers entirely…
