EI Williams designs custom built silencers including vent silencers, engine silencers, fan silencers and industrial silencers to meet all system requirements. We also have as part of our product line; thermal insulation blankets and industrial catalytic converters.

Industrial Fan Silencer for Fan Noise Reduction

You are in all probability not going to become on the lookout for lots of “peace and quiet” on the shop floor, but you as well as your employees and colleagues are working there for hours at a time. You may even want to possess a conversation, or simply hear yourself feel. Industrial fans can add to the noise level, but luckily, you'll be able to accomplish fan noise reduction by way of an industrial fan silencer. Get far more data about vent silencer

Calculating Noise Levels

With no having too technical right here, there are 3 units of measure related to industrial fan noise levels, including:

Fan Sound Pressure (Lp)

Fan Sound Power (Lw)

Decibels (intensity of sound (dB))

The Air Movement and Control Association (AMCA) offers testing requirements for fan Lw levels, that are derived via calculations most effective done by your application engineer and/or an acoustical engineer. Based on a June 2017 write-up in Processing Magazine, common industrial noise levels from a fan application can variety from about 70-120 dB. You might also discover an in-depth discussion of fan sound measurement and calculation inside the article, titled Understanding Fan Acoustics.

Your fan manufacturer needs to be able to provide you a strong get started by delivering you using the expected sound power and pressure levels their fan will deliver based on its surrounding situations. Then, primarily based on your application, we'll frequently propose a fan silencer to deal with any application-specific industrial fan noise reduction specifications. Put simply, we can hear the distinction.

Safety: How Loud is Also Loud?

Each individual includes a unique interpretation and amount of tolerance for excessive noise. You might not be satisfied until your music is “turned as much as eleven” while your pal might be blasted out from the area at five.

But, according to the Occupational Health & Safety Administration (OSHA), there are some noise level thresholds that employers must listen for, measure, adjust, protect and/or moderate primarily based on length of exposure.

According to OSHA’s website, “OSHA has established permissible noise exposure limits to help avoid the standard threshold shifts in working. If the noise level exceeds 85 dBA on a time-weighted average, a hearing conservation program is required. The actual exposure limits are given in Table 1. (Review OSHA’s occupational noise exposure 1910.95 to get a full explanation.)

Fan Silencer for Industrial Fan Noise Reduction

An open fan inlet or outlet is a common culprit behind excessive noise levels. An inlet and/or outlet silencer can adequately reduce the noise levels for many of these applications. You can find other factors and solutions to consider, but we will address those in future posts.

Factors in selecting inlet fan silencers include the kind of fan (centrifugal or axial), the configuration of your ductwork, the allowable drop in pressure, and of course, how much industrial fan noise reduction is required. At the discharge of your fan, you’ll have to have to also consider velocity, pressure and temperature control, as well as material handling needs and corrosion resistance.

Once you assess all of these factors, you may be ready to select the optimal fan silencer for industrial fan noise reduction.
