Dura-Life™ bag filters are engineered with a unique hydro-entanglement process that uses water to blend the bag fibers, creating a more uniform material with smaller pore size that provides better surface loading of dust and prevents penetration deep into the media.

In contrast, conventional polyester bags are manufactured with a needling process that creates larger pores where dust can embed into the fabric, inhibiting cleaning and reducing filter bag life. With better surface loading, Dura-Life bag filters provide improved pulse cleaning and a lower pressure drop, which results in extended bag life, less maintenance time and cost, energy savings and greater filtration efficiency.

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

Pressure drop increases at a faster rate with needled polyester bag filters due to dust embedding in the media, shortening bag life and forcing more frequent bag changes. Dura-Life filter bags, with surface loading of dust and better pulse cleaning, perform well when replacing due to excessive pressure drop.

Dura-Life Clears the Air Better - 30% Fewer Emissions

Dura-Life bag filter media has been shown to produce lower emissions than the 16 oz. needled polyester material used in most standard bags. Dura-Life 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 Bags are the Clear Choice for Savings

Dura-Life filter bags should help support fewer bag changes, resulting in labor and replacement bag savings and less production downtime. Unique Dura-Life technology traps dust on the surface of the bag, allowing dust to be easily pulsed off during cleaning resulting in lower pressure drop and annual energy savings.

Annual Energy Savings Due to Reduce Pressure Drop

This is one example; energy savings can further increase with larger collectors. These energy savings are calculated based on the following assumptions: Baghouse collector runs 2 shifts per day, 5 days a week (4,000 hours per year) and energy costs are 10.7 cents per kilowatt hour with Variable Frequence Drive and an EISA compliant motor.

These calculations are based on the following assumptions: standard polyester bag filters are replaced annually, Dura-Life bag filters provide twice the life of standard polyester bag filters, time-and-a-half labor rate equals $45/hr. including benefits, and a three-person crew can replace 40 bags/hr. Labor and bag cost savings can further increase with larger collectors.
