Ultra-Web | High Efficiency Cartridge Collector Filters | Donaldson Industrial Dust, Fume & Mist

Overview

Offered for a full range of dust, fume and mist collection applications, Donaldson Ultra-Web® filters outperform and outlast other filters.

Ultra-Web is proprietary and made with an electrospinning process that produces a very fine, continuous, resilient fiber of 0.2-0.3 micron in diameter to form a permanent web-like net. This fine fiber “web” with its very fine interfiber spaces is constructed onto tough cellulose substrate media, resulting in:

A more robust media that captures even submicron dust on the surface
Better pulse cleaning and lower pressure drop
Cleaner air, longer filter life, and greater cost savings

The animation above is a high-level demonstration of a traditional cartridge media cross-section. There are larger fibers on the right with a fine fiber layer on the left-hand side. The role of a dust cake in a continuous-duty collector is to help filter particulate, increasing the efficiency of media while the residual dust helps rebuild the beneficial dust cake after pulsing.
