Dura-Life — A Breakthrough For Bag Users

Polyester bags are woven with a needling process that creates larger pores where dust can imbed into the fabric, inhibiting cleaning and reducing bag life. Dura-Life bags are engineered with a unique hydroentanglement process that uses water to blend the fibers, resulting in:

• More uniform material with smaller pore size
• Better surface loading of dust that prevents penetration deep into media
• Improved pulse cleaning and lower pressure drop
• Bags with longer life and greater value

These photos were taken with a scanning electron microscope of bag media within a collector that was filtering fly ash. The bags were removed after 2,700 hours of use. Air-to-media ratio was 4.5 to 1. Pressure drop was 6 in. on polyester bags and 2 in. on Dura-Life.

Dura-Life Bags Last 2-3 Times Longer
Than Standard Polyester

Pressure drop increases at a faster rate with polyester bags due to dust imbedding in the media, shortening bag life and forcing more frequent bag changes. Dura-Life bags, with surface loading of dust, better pulse cleaning and a lower pressure drop, perform far longer than polyester bags.

These results were derived in accelerated lab tests, which correlate to field tests results, showing that Dura-Life will provide 2-3 times more life than standard 16 oz. polyester bags in most applications.

Dura-Life Clears the Air Better

Durapex media used in Dura-Life bags has been shown to produce 30% lower emissions than the 16 oz. polyester material used in most standard bags. Dura-Life’s Durapex media is more efficient at capturing dust, even 2.5 micron or smaller particles, reducing the amount of dust that escapes into the air. This helps to keep the workplace and environment cleaner. Dura-Life’s Durapex media has been tested and received EPA PM 2.5 performance verification from the Environmental Technology Verification (ETV) Program via ASTM D 6830-02.
