Fan Silencing – an efficient, low cost alternative to silencers

Fans are a common industrial noise problem. Imagine if you could make them both quieter and more efficient, making silencing profitable…

Did you know it’s possible to reduce industrial fan noise and to improve fan efficiency using innovative aerodynamic technology instead of silencers? The technique is not only a fraction of the cost of silencers, but the efficiency gains can often make fan noise control projects profitable. We can evaluate the control options for most fan noise problems for you (free) by email if you send us a couple of photos and a smartphone video or noise recording (for more on this, visit – remote control of fan noise).

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 a fraction of the 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…
