Ultra-Web® Cartridge Filters

Donaldson®
ultra web cartridge filters for dust collection

Industry-leading filtration

Donaldson Ultra-Web® filters are made with a proprietary electrospinning process to produce a very fine, continuous, resilient fiber. This fiber “web” has very fine interfiber spaces and is constructed onto a tough cellulose substrate media.  

Ultra-Web filters offer several advantages over other types of filter media, including: 

  • A more robust media that can capture submicron dust particles 
  • Better pulse cleaning and lower pressure drop 
  • Longer filter life and cleaner air 
  • Greater cost savings 

These filters perform well on extremely fine, dry, and nonfibrous dust. Flame retardant media is also available.  

Key Benefits

  • Substrate media offers higher durability and better cleanability 
  • MERV 15 filtration efficiency rating per ASHRAE 52.2-2012 
  • Energy savings due to lower pressure drop 
  • Longer filter life, which reduces replacement and maintenance costs 
  • Lightweight, easy to install cartridges 

Key Applications

  • Fumed silica
  • Metallic fume
  • Metallurgical powders
  • Oily weld fume
  • Pharmaceutical compounds
