New filter elements help your company meet increasingly stringent emissions standards while also reducing energy use, minimizing maintenance requirements and increasing operational efficiencies.
 PROBLEM:
Due to the abrasive nature of dust materials, the bags have to be changed rather frequently—every six months was common—and they often limit the actual cubic feet per minute (ACFM) airflow of the collector, making it difficult for the company to achieve their material handling and production goals.
SOLUTION:
The filter bags were replaced with 100% non-woven, spunbond, pleated filter elements to produce greater dust collection efficiencies. Additionally, the pleated elements were designed to resist wear from abrasive materials, enabling them to last two to three times longer than the felt bags in the same environment.
RESULTS:
In side-by-side stack efficiency testing, the pleated filters were 58% more efficient than 16-oz polyester felt bags in reducing emissions. The pleated elements also increased the collector’s airflow by lowering the deltaP across the filter. Dropping the deltaP by 4” saved approximately $9,198 annually (operating 24 hours a day, seven days a week, 365 days a year @ $0.07 kw).
While the pleated elements won’t provide 200,000 ACFM in a 100,000 ACFM baghouse, they can optimize both the operationalefficiency and throughput of existing baghouse systems. In addition to helping manufacturers meet more stringent emission standards, the pleated filter elements can provide thousands of dollars in savings compared to bag filters. |
