Tensioning plays an important role in successful operation of filter bags in reverse air bag house. Improper tensioning is one of the main causes of bag failure. Excessive tensioning of the bag results in unnecessary stress to the fabric and sewing thread of the bags, and typically failures occur around the cuff and anti-collapsible rings. Insufficient tension causes excessive horizontal movements causing bag to bag abrasion.

Pneumatic Tensioning Tool is a precision tensioning device that provides accurate and consistent bag tensioning. Equal and adequate tension is applied to all bags maintaining uniformity. Tensioning of filter bags vary from 50 to 75 pounds depending on the diameter of filter bags.
