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 fine fiber 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. Clean Ultra-Web Filter Surface-Loaded Ultra-Web Filter Ultra-Web fine fiber 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. 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. 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. *MERV 15 available in U.S. only. 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 fine fiber media is the most optimized and cost-effective choice available for most dust and fume collection applications. Experience the Ultra-Web Advantage Increased surface loading Enhanced dust cake release Better cleaning efficiency Lower cost per cfm Available for most brands of dust collectors We can help you get the optimal solution for your application.
