The problems that can result from poor media selection are numerous, but some of the main ones include: failure to comply with emission standards, excess energy use, shortened filter life, and dust collector failure. A thorough site survey, coupled with dust testing performed by a qualified lab, can help determine the right media for a given application.
Also, explosion hazards and compliance with new NFPA standards and OSHA guidelines are of major concern when selecting media in combustible dust applications. Carbon-impregnated media filters are very effective because they are conductive, providing a “static drain” on the media that eliminates the chance of a spark or ignition source from buildup of static electricity in the media.
