Industrial fans and extractors are essential for ventilation, dust extraction and process support in factories across the UK. However, the noise they generate can create two major problems: high noise exposure for workers and nuisance complaints from neighbours. We specialise in fan noise reduction techniques that deliver high noise reduction and large cost savings compared with other methods.
Fan noise problems often persist because common noise control products such as acoustic enclosures, screens or standard silencers are chosen without diagnosing the main source of the sound.
These products can be expensive and, in many cases, fail to reduce the noise to an acceptable level, particularly when the problem involves low frequency hums and drones. Our approach focuses on suppressing the noise at source using advanced technology and engineering solutions tailored to the specific fan and system.
Key Aspects of Effective Fan Noise Reduction
- Diagnostic Noise Surveys: Before recommending any treatment, we carry out detailed diagnostic noise surveys using specialist equipment. This identifies the main noise radiating surfaces and quantifies how much sound reduction is needed. Correct diagnosis avoids wasted expenditure on ineffective measures.
- Advanced Noise Cancellation: In many instances, the most effective approach is to cancel the noise at source rather than simply try to block it. Our specialist solutions have achieved reductions of up to 30 dB, usually making the fan inaudible at the nearest property.
- Purpose-Designed Silencers: Where appropriate, we design custom silencers that deliver high attenuation with minimal airflow resistance. This ensures fan performance is maintained while achieving high noise reduction. Standard off-the-shelf silencers typically offer only modest improvements in the sound level.
- Cost Efficiency: Many companies spend far more than necessary on enclosures or screens that do not solve the problem. Our solutions frequently deliver better results at a fraction of the cost, with savings often running into tens of thousands of pounds.
Benefits of Specialist Fan Noise Solutions
- Greater noise reduction than conventional treatments
- Solutions tailored to specific fan characteristics
- Maintains system performance and airflow
- Reduced likelihood of future noise complaints
Fan noise can be complex, especially when nuisance complaints or regulatory limits come into play. Our expertise means we can help you choose the right solution, avoid ineffective treatments and resolve fan noise problems efficiently and in the most cost-effective manner.
