The wide variety and number of fans and blowers used in industrial processes and ventilation applications today represent one of the leading contributors of noise related issues, in terms of worker health and safety, and satisfying environmental regulations.
offers a number of different absorptive designs for use on fan inlets and outlets of every type and size. We specifically select fan silencers to meet the noise reduction needs of the application, taking pressure drop and space limitations into consideration.
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:
PD blowers are prone to destructive low frequency pulse generated noise. Often, they can also have high mid-to-upper band noise levels. In many cases this means that blower silencers are necessary on both the open air inlets and pressurized discharges of PD blowers.
When blower pitch line velocity (PLV) is below the blower's critical speed, low frequency noise tends to dominate and a reactive blower silencer is probably the right choice. If the blower's PLV is above its critical speed, then a reactive-absorptive silencer should be used due to the presence of high mid-to-upper band noise, as well as low frequency pulses.
