The field of industrial ventilation and dust collection has come a long way in the past 25 years. Stringent governmental regulations regarding dust emissions coupled with an increased focus on worker’s health and safety have encouraged dust collection technology to become more efficient, more effective, and at times more complicated than ever before. However, even with all of the recent technological advances in dust collection there still exist some of the same problems that have plagued us for decades.

In the 1985 U.S. Department of Agriculture Forest Service Handbook titled “Utilization of Hardwoods Growing on Southern Pine Sites”, the issue of dust collection as pollution control is addressed in regard to the production of structural flakeboards and composites such as those used in roof sheathing, wall sheathing, and sub-flooring.

As you can see many of the same dust collection issues faced 25 years ago continue to challenge us today. As stated in this excerpt, “dust collection systems following the dryer collector have difficulties because the steam content in the gases condenses in cold weather” and “bag collectors are particularly susceptible to any condensation, even with high-temperature resistant bags, and any spark or fire in the system will destroy the bags and frames, requiring costly replacement and downtime.” As many plant managers and engineers know, problems with condensation, high heat, and replacing expensive filter media still exist as challenges for many dust collection systems.

The Aerodyne dust collector featured in this handbook is still recommended as an effective solution to many of the problems faced in difficult dust collection problems today.
