Pleated dust collector filter bags offer an alternative to optimize collector efficiency without requiring a larger collector case. Each pleated bag contains 300% to 500% as much media as a conventional dust collector bag. Additionally, pleated bags are easier to clean than conventional felts because they are surface loaded, meaning the dust doesn’t penetrate the media’s surface. This feature also produces a lower pressure drop, making them economical to operate. Sly’s Toploaded dust collector pleated bags are exceptionally easy to replace. They have a snap band collar which is compression-fit by hand to the collector’s tube sheet. Unlike other similar dust collector bags, some styles do not require a tool to pry out when being replaced. Pleated bags are also available for bottom access designs.
