NEW: fan silencer by dB Noise Reduction

Industrial fans move large amounts of air and other gases, often at high pressures, temperatures and velocities. The noise generated can be significant, and often problematic at the fan's blade passage frequency. Fan outlet silencers are essential in controlling this type of noise.

The dB Noise Reduction line of equipment includes outlet silencers for a broad range of fans and applications. Features include:

Special configurations to minimize pressure drop on high velocity fan discharges

Floating baffle designs to accommodate high temperature thermal expansion

Cleanable/replaceable baffle silencers for dirty gas applications

Corrosive resistant materials and PTFE liners for corrosive gas streams

NEW: motor silencer by dB Noise Reduction

The fans on TEFC motors can often result in noise levels approaching 95 dBA, which is considered unacceptable in most industrial settings.

dB Noise Reduction offers an elbow type motor silencer employing aerodynamically designed long radius elbow baffles (CR = 0.5) for maximum attenuation and minimum pressure drop. Motor silencer connections are selected to exactly fit the motor fan inlet diameter and the internal silencer area is matched to the connection area so that there are no changes in air velocity. ...

NEW: compressor silencer by dB Noise Reduction

dB Noise Reduction will evaluate the configuration of your compressor, noise level requirements, temperature limits, pressure rating and overall system in selecting the proper compressor silencer for the job.

Our compressor silencers offer: Maximum sound absorption Minimal airflow restriction and pressure drop Noise attenuation to meet application needs Reciprocating compressors exhibited destructive low frequency pressure pulsations and noise. Therefore, in most cases, it is essential to use a reactive inlet compressor silencer to dissipate the pulse energy. If high mid-to-...
