For industrial environments that deal with a lot of grinding, sanding, polishing, etc., having a dust collection system integrated into the facility is almost a necessity these days. As the concern for employee safety and shop air quality continues to grow, dust collection systems are becoming more important than ever.

There are benefits to using centralized systems, but there is also a minimal margin for error. Evaluating an application and designing a system to accommodate that application can take a turn for the worse if not carefully thought out; that means not only the equipment itself, but the ductwork layout must be precise, otherwise failure could result. Each type of machine or tool, whether it’s used for grinding metal gears or hogging wood shavings, will have its own airflow requirement. Once the total airflow requirement has been determined, the length and amount of ducting must be considered in order to properly calculate the pressure differential, to ensure that all of the tools are getting their assigned flow rate while overcoming the pressure drop through the duct.

It’s as important to have the proper duct design as it is to have the proper dust collection system to ensure optimal system performance. One not-so-common mistake that is made is the type of ductwork that is used; of course, one would assume not to use residential furnace duct to network saws and routers to a cyclone capable of producing 10,000 cfm; but alas, people do it from time to time, resulting in collapsed ductwork.

Improper use of dampers can also render a dust collection system less effective or useless; if you have multiple machines in a line, for example, improper airflow balancing amongst them can easily result in some of the machines not getting suction whatsoever. Sometimes, properly sizing a dust collection system can be a daunting task, especially if there will be equipment additions in the future. It can be difficult, almost impossible, to be able to assume precisely what size and equipment type will be added down the line; this makes oversizing the dust collector a little harder, but it is still possible…it will be up to the user to properly duct and balance the system accordingly.
