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.
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.
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.
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.
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.
