Ultra-Web® SB cartridge filters offer the unmatched surface loading capabilities of our standard Ultra-Web filters with a spunbond substrate that stands up to more abrasive dusts, harsh chemicals and moisture.
The proprietary Donaldson Ultra-Web media employs a web of very fine, resilient fiber 0.2-0.3 microns in diameter to catch submicron dust particles at the surface of of the filter. This prevents particulates from settling in deep in the filter substrate, allowing Ultra-Web SB cartridge filters to last up to twice as long as traditional filters. The result is a filter that lasts longer, cleans better and costs less to operate than competitive filters. A wide range of styles and sizes fit most popular brands and styles of collectors.
