by Janet H. Thomas, RID At the Greening the Heartland Convention held in Indianapolis, Indiana last week I was intrigued by a presentation on Fume Hood Technology. Erlab GreenFumeHood system combines innovative product with a pollutant filtration process that allows dirty air to be cleansed via absorption within the filter medium and provides clean air for recirculation within the hood enclosure. Traditional Hepa filters entrap contaminants on the filter surface as they are pulled through the exhaust system. The Neutradine filter module chemically alters contaminants, breaks them down and releases clean air. This process eliminates the need for ducted exhaust, greatly reducing the amount of air exchange needed within the lab environment, eliminating costly ductwork runs and providing operating and maintenance savings. Hoods are easier to relocate and they are not chemical specific. When it is time for filter replacement, they are incinerated, producing only carbon dioxide and water as byproducts. Jim Hill from BSA Lifestructures presented a case study of a recent Organic Chemistry lab renovation at Butler University. The GreenFumeHood was chosen for its ability to save renovation costs, reduce operation costs and meet a restricted timeline for project completion. While the technology will not be usable for all fume hood projects, it demonstrates the steps being taken towards environmental awareness in the lab environment.
