The unique PulsePleat^® media is unlike traditional felt or woven fabrics in that it has a tight pore structure which resists penetration of particulate and has rigid physical properties that allow it to hold a pleat without the need for supporting backing material. The media is pleated and molded into a filter element that can increase filtration surface area 2 to 3 times compared to conventional filter bags, dramatically increasing filtration efficiency while operating at significantly lower differential pressures.

Spunbond Media vs. Traditional Needle Felt

Tight calendering of spunbond media fibers resists particulate penetration into the media.

Spunbond media is manufactured by layering fine denier fibers from multiple spinning heads onto a moving mat. This depth of fibers is then calendered under heat and pressure. Spunbond media can withstand temperatures up to 135°C.
