2STTop or Bottom Load

The AJR-PLEAT 2ST series of pleated bag dust filter elements are uniquely designed with a two-stud top cap design, adaptable for common industry 6” nominal diameter top or bottom dust load dust collector styles (with the addition of converter hardware by others.) Galvanized end caps and core complete the filter’s rugged construction, making the 2ST replacement filter an excellent choice for many legacy dust collector installations in industrial applications today.
