Donaldson Case Study on Filter Life Improvement

This case study presents the application of Donaldson Torit-Tex™ pleated bag filters in a food ingredient manufacturing facility facing premature filter failure and high compressed air usage due to dust caking. The document outlines the challenges encountered by the manufacturer, including frequent filter changeouts and increased production downtime caused by the fine nature of the product dust and the humid climate. It details the recommended solution involving the transition from traditional bag filters to Donaldson's pleated bag filters featuring spunbond polyester media and Tetratex® PTFE membrane. The study explains how the new filter assemblies provide up to three times more filtration area, resulting in reduced system pressure drop, longer filter life, and decreased compressed air consumption. The results indicate a significant improvement in filter longevity and air quality, leading to a decision to upgrade all dust collection equipment to pleated bag filters.
