Essential Components of an Industrial Ventilation System

Posted by Josh Janecek on Apr 20, 2016 12:55:14 PM

A well-functioning industrial ventilation system is more than just supply and exhaust fans. Sure, it all starts with exhausting stale air out and bringing outside air in, but there are ways you can optimize your system and keep your equipment working better and longer, and your employees more comfortably. Depending on your specific situation, you may need any combination of the following pieces of equipment.

Everything You Wanted to Know about Air Filters

Posted by Gary Leseman, P.E. on Feb 18, 2016 3:10:57 PM

We’ve been designing ventilation systems with air filters for many, many decades. In this time, we’ve come to realize that sometimes a customer might expect air filters to actually filter out sound as well as particulates. It seems like a logical conclusion, but it’s actually pretty far from the truth. Here are some thorough answers to some of your most common questions.

Silencing Noisy Equipment on Offshore Rigs

The problem with noise on MODUs

The men and women who work on offshore rigs are exposed to many environmental factors that can have an adverse effect on their work performance as well as their overall psychological well-being.

Unfortunately, we have experienced first-hand what excessive noise can do to one’s hearing. Uncontrolled noise can be detrimental to workers’ health, and in some cases, it can even cause permanent, irreversible hearing damage.

Different regulatory bodies have set forth criteria for noise and other environmental factors to keep personnel working safely and efficiently. As ABS states in their Guide for Crew Habitability on Mobile Offshore Drilling Units (MODUs), “These habitability criteria have been chosen to provide a means to help reduce personnel fatigue, improve performance and safety, and to assist with personnel recruiting and retention.”

How to Measure Fan Noise

Fan Noise – Some Sound Basics

Sound is a physical occurrence. Sound is also what we hear. Interestingly, “sound happens” whether or not anyone is around to actually hear it. Fortunately, sound is governed by natural laws so we can measure, predict, and use it to our advantage just like the fan performance is governed by the Fan Laws.

So, what’s the difference between sound and noise? Simply stated, noise is unwanted sound. Noise is relative to the ear of the listener. I may like classic rock & roll music, but to someone else—it’s just noise.

Determining how noisy a fan is and what to do about it is not as straightforward as one might think.
