FORST Washable Dust Bag Filter Cartridge: Developed to replace traditional filter bags and cages, each pleated bag filter has a one-piece construction design which allows it to be used in new systems or as a simple retrofit in existing bag house equipment for improved system performance. Pleated bag filters offer more filtration media than traditional felt bags increasing the filtration surface area and thus the filtration capacity. With up to 2-3 times the filter life over traditional 16 oz. Polyester felt bags, pleated bag filters provide almost twice as much filtration area in existing equipment due to increased media in the pleat pack design. This increased filter area causes the air-to-media ratio to decrease when the airflow stays the same, dramatically increasing filtration efficiency while operating at significantly lower differential pressures. Pleated bag filters are shorter than standard fabric bags which allows for larger drop out area and less opportunity for bag abrasion. Many installation methods to meet all the working conditions, Available in a variety of configurations for top-load, bottom-load and oval styles with multiple filter media options including ePTFE (expanded polytetrafluoruethylene) and spunbond polyester.
