Ultra-Web Media Technology

 
Proprietary Technology that Performs
Proven and proprietary Ultra-Web® technology delivers longer filter life, cleaner air and greater cost savings than other types of cartridge filter media. Made with an electrospinning process that produces a very fine, continuous, resilient fiber of 0.2-0.3 micron in diameter, Ultra-Web forms a permanent nanofiber web with very fine interfiber spaces that trap dust on the surface of the media.
  • Superior media is more efficient in capturing submicron dust particles
  • Longer filter life and better pulse cleaning due to surface loading technology
  • Lower energy and less compressed air use with better pulse cleaning and lower operating pressure drop
  • MERV 15 and 14 filtration efficiencies to meet specific application needs

Three decades of longer filter life
For more than three decades, Donaldson Torit has advanced our Ultra-Web technology to provide a complete line of cartridge filters, PowerCore filter elements, and pleated bags that last up to twice as long as commodity cellulose and cellulose/synthetic (80/20) blend medias. Pressure drop starts high and rises quickly with depth-loading commodity filters, resulting in shorter filter life and greater energy use. Ultra-Web’s surface loading technology is scientifically proven to provide lower operating pressure drop over a longer period of time, which allows the filter to last longer while requiring less energy.
 
Lower Pressure Drop  
Results were derived testing Atomite test dust in an 8-cartridge collector @1.0 gr./cu.ft, Goyen Millennium valves, 90 psi cleaning pressure, 100ms on time 10 second off time. Airflow goal = 4064 scfm.
​Clean Ultra-Web Filter
Surface-loaded Ultra-Web Filter
 
​Ultra-Web nanofiber media is loaded with ISO fine dust. Dust particles collect on the surface of the media and clean off easily while the substrate stays clean. A depth-loading filter would allow dust particles to penetrate deeply into the substrate where they build up and choke off the airflow. ​
Engineered to Perfection
A filter must be rated at least a MERV 13 on the ASHRAE 20-point scale to effectively filter submicron dust particles during ASHRAE 52.2 testing. Donaldson® Torit® has perfected our standard MERV 15-rated Ultra-Web filters to optimize filtration without sacrificing filter life or increasing pressure drop.
For applications that require even higher intial efficiency, there’s an Ultra-Web filter to meet your needs.


Ultra-Web efficiently captures submicron dust particulate. Cellulose and 80/20 blend media are not efficient enough to rate on submicron dust particulate. Typical cellulose and 80/20 blend media are rated to capture 1-3 micron dust particles and some competitive 80/20 blend media is only rated to capture larger 3-10 micron particulate.
*Not efficient enough to rate
 

Higher Efficiency = Cleaner Air

 
Ultra-Web MERV 14 and 15 efficiency has been certified by independent lab tests and tested per the ASHRAE Standard 52.2-2007, the most current industry accepted test method used to evaluate filter performance.
Count on Significant Savings
Savvy engineers with their eye on the bottom line know that Ultra-Web equals significant cost savings. Ultra-Web filters last longer, resulting in fewer filter changes, lower replacement and labor costs, and less production downtime. With lower pressure drop due to surface loading of dust, the energy and compressed air costs are also dramatically lower. For proven technology that delivers energy, maintenance and filter cost savings, there’s only one solution—Ultra-Web.
Ultra-Web nanofiber media is the most optimized and cost-effective choice available for most dust and fume collection applications.
