Donaldson Fibra-Web® cartridge filters feature a wide pleat spacing designed to improve the efficiency of pulse cleaning of fibrous and agglomerative particles.

The synthetic substrate is covered with a web of very fine, resilient fiber 0.2 – 0.3 microns in diameter to catch very fine dust particles at the surface of the filter. This prevents particulates from settling in deep in the filter substrate. The result is a filter that lasts longer, with significantly lower pressure drop than competitive filters. A wide range of styles and sizes fit most popular brands and styles of collectors.
