PulsePleat® Pleated Filter Elements

The media is pleated and molded into a filter element that can increase filtration surface area two to three times compared to conventional filter bags, dramatically increasing filtration efficiency while operating at significantly lower differential pressures.

Many industrial air filtration systems are being pushed past their design limits. With increased production demands and tighter emissions limits, many systems are failing to keep up with today's needs. As an alternative to a costly replacement of industrial air filtration systems, GE's PulsePleat® filter elements provide superior quality and performance for improving existing dust collection systems.

GE's PulsePleat® filter element is a one-piece pleated product made of spunbond polyester media that replaces conventional filter bags and cages. This unique media is unlike traditional felt fabrics in that it has a tight pore structure, which resists surface penetration of particulate matter and has rigid physical properties that allow it to hold a pleat without the need for supporting backing material. The pleated media is molded into a filter element that can increase filtration surface area two to three times compared to conventional filter bags, dramatically increasing filtration efficiency while operating at significantly lower differential pressures.

Compared to conventional filters, PulsePleat® filter elements cut costs and provide environmental benefits by reducing energy requirements, particulate matter emissions and the amount of disposed filter media over the lifetime of the filter.

Specifically, PulsePleat® filters require less cleaning energy compared to regular filters, requiring 4,933,131 fewer pulses per year of compressed air for cleaning and therefore saving 825,025 kwh per year - the equivalent amount of electricity needed to power 77 average U.S. households for a year.

PulsePleat® provides operational benefits as well by providing more airflow. In a typical asphalt manufacturing plant, for example, air flow will be increased on average 40 percent compared to the capacity of a conventional filter. This correlates to a 30 percent increase in throughput production within the plant, which could equate to 178,100 additional tons of asphalt per year—enough to resurface 112 lane miles of roadway.

PulsePleat® filter elements also reduce particulate matter emissions in a typical aluminum manufacturing plant by 21,000 pounds per year. This particulate matter can be reclaimed back into the manufacturing process and is enough material to produce 355,950 aluminum beverage cans.

Because they last four times longer than conventional filters, using PulsePleat® filter elements in place of conventional filters over the average three-year lifetime of a PulsePleat® would save 99,500 pounds of polyester material. Manufacturing this much polyester would require more than 4,900 barrels of oil.
