downflo II dust collectorsengineered for reliableperformanceThe long-standing, most influential cartridge collector in industrial air filtration history, the Donaldson Torit Downflo II (DFT), delivers optimum performance and is one of the best values available in today’smarketplace. A leader in the industry for over 20 years with thousands of successful installations in place,DFT dust collectors ensure steadfast, trouble-free operation.The DFT advantages can be found in the collector’s proprietary design and components. Now featuring aledgeless design in combination with proprietary Ultra-Web filter media and proprietary cleaning technology,the DFT continues its strong performance in traditional applications such as metalworking. It also generatesinterest and respect in process applications where ledgeless construction is often a requirement. Providinghigher efficiency and smaller footprints than any baghouse collector or even other cartridge collectors, DFTadds up to long-term savings and improved performance in many applications.DFT Offers: Ledgeless constructionEliminates dust build-up and accommodateswash down environments Compact designMinimizes floor space. Powerful performanceProprietary ExtraLife Filter Cleaning Systemprovides 30% more cleaning energy Cost savingsFewer filter changeouts, reduced filter disposalcosts, less energy usage ReliabilityExceptional results for over 20 years and counting Easy system setup Easy maintenance 10-year warrantyAleaderin the industry for over20 years1Donaldson ToritDFT 3-6

downflo II dust collectorscartridge filter technologyUltra-Web Nanofiber Filter MediaDonaldson leverages almost 100 years of air filtration experience in the development of filtration media,providing tremendous value to our customers. Ultra-Web media incorporates a durable layer of premiumnanofiber designed to intercept the smallest dust particles at the surface of the media.Independent laboratory testing determined that Ultra-Web media has a Minimum Efficiency ReportingValue (MERV) of 15 based on the ASHRAE 52.2-2007 test standard. Ultra-Web media rated MERV 15 is themost optimized, balanced and cost-effective media in the marketplace, providing higher efficiency withoutcompromising pressure drop and filter life. For more information on Ultra-Web and MERV ratings,please visit www.ultrawebisalwaysbetter.com.10 micron10 micronNanofiber Media(600x)Nanofiber surface loading technology is availablein all Ultra-Web and Fibra-Web cartridge filters.Commodity Filter Media(600x)Conventional media has spaces of up to 60 µm betweenfibers, allowing dust to become deeply embedded.system energy efficiency, savings,and noise controlSurface loading is a key characteristic of Donaldson's Ultra-Web media. This surface loading capabilityimproves the effectiveness of pulse cleaning, which minimizes system pressure differential; thereby conservingcompressed air usage and brake horsepower requirements of the system fan.Clean Ultra-Web FilterSurface-Loaded Ultra-Web Filter(substrate still clean)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.DFT Cartridge FiltersDFT dust collectors’ proprietary downward airflow design delivers highest filtration performance whileusing less energy. The DFT collector, its proprietary ExtraLife Filter Cleaning System, and DonaldsonTorit’s cartridge filters together are an unbeatable system. Choose from our superior line of filters tocomplete the most powerful dust collection solution available.5Donaldson Torit
