The PB50048-FTL-H4-SB45 is a rugged, high-surface-area pleated bag filter designed to replace traditional filter bags and cages in pulse-jet style dust collectors. With its flat-top latch (FTL) mounting design and spunbond polyester (SB) media, this filter offers exceptional durability, washability, and improved airflow, making it ideal for abrasive or humid dust environments.
Measuring 5 inches in diameter and 48 inches in length, this filter includes 45 pleats for a significantly larger surface area than standard sewn bags. It features an H4 extra heavy-duty internal support cage to withstand high-pressure cleaning cycles and maintain pleat integrity over time. The SB media resists wear, moisture, and bridging — extending service life in demanding applications.
This filter is commonly used in industries such as grain, agriculture, feed, fertilizer, cement, and food processing, particularly where durability and reusability are required.
