FILTRATION SOLUTIONS FILTRATION SOLUTIONS FOR THE MINERALS INDUSTRY Tetratex® ePTFE Membrane Filter Media: • Optimizes filter performance • Increases bag life and production rates • Reduces downtime

FILTRATION CHALLENGES Reducing energy consumption and environmental emissions are two of the greatest challenges facing the minerals industry today. Donaldson Membranes’ Tetratex® ePTFE filter media can help overcome these challenges. Tetratex filter media can enhance the performance of your fabric filter by utilizing surface filtration technology as opposed to traditional depth filtration methods. The benefits of Reduced Energy Consumption Significant savings in power consumption can be achieved by maintaining required airflow at a reduced filter DP Surface filtration principles inhibit particle...
