Dust Collection by Double-sided Benchtron
Project:
A worldwide manufacturer of compressed air systems was having quality issues with contamination of painted parts from the fabrication areas. Several types of dust collection methods were tried, but they were not effective enough to stop the issue. The customer was looking for a method to capture welding fumes and grinding dust that was effective, worker-friendly and would not inhibit material flow when working with large assemblies. Another major issue was that an overhead crane system that ran over the production area precluded tall or ducted systems. The potential for combustible dust from sanding and grinding on aluminum parts was another consideration.
Solution:
Air Purification Inc. was called in to investigate and recommend suitable methods to collect and filter the pollutants while allowing workers full access to the assemblies being fabricated. After examining customized downdraft tables, source capture arms and ambient filtration systems, the best approach was determined to be customized capture booths. Filter-1 manufactured the DCB-12 (dry) and HWF-3 (wet) self-contained dust collection booths in the required sizes – all systems use in-booth Regain Air for high capture velocities to keep worker breathing zones clear. Filtration capabilities are up to 99.9% filtration using nanofiber filters. Because some parts needed to moved by cranes, each booth was designed to provide a full-length 18” wide crane slot built into the roof to allow hoisting and positioning of the welded assemblies.
Result:
The custom dust collection booths have been successful in keeping all of the contaminants from migrating to the paint area and provide the workers with a cleaner working environment. The welded assemblies are easily moved into and out of the booths with the overhead cranes.
