Overview of Ultra-Web® SB Cartridge Filters

Donaldson Ultra-Web SB cartridge dust collector filter | AIRPLUS Industrial

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 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 collector.

Features:

  • Spunbond substrate stands up to higher temps, chemicals, moisture and abrasive dust
  • The very fine fibre web traps dust on the surface of the filter
  • Increased surface loading for prolonged filter life and lower pressure drop
  • Enhanced dust cake release during pulse cleaning increases filter life
  • MERV 15* filtration efficiency to meet specific application needs
  • Electrospinning process produces exceptionally strong fibres as small as 0.2-0.3 microns in diameter
  • Stainless steel construction is available
