Downflo Oval - Dust Collectors - Brochure

Downflo® ovalDust collectorsThe high performance Downflo® Oval (DFO) family of over-achieving dust collectors provides up to 25 percent more filtration capacity than other same-sized cartridge collectors. Powered by proprietary Ultra-Web® nanofiber filtration technology, DFO delivers cleaner air, up to two times longer filter life, and greater cost savings.The DFO advantage is found in the collector’s proprietary design and components. The combination of a new cabinet design that greatly lowers cabinet velocities, proprietary Extra-Life™ cleaning technology, and proven Ultra-Web nanofiber filters allows more airflow through the collector without increasing the size of the footprint or damaging the filters.A smaller collector helps lower the initial purchase price, reduces filter replacement costs and opens up valuable manufacturing floor space.DFO offers:• Lower initial cost per cubic foot of air per minute• Higher efficiency—cleaner air• Lower pressure drop— greater energy savings • Fewer filter changeouts• Reduced filter disposal cost• Easy system setup• Less maintenance • 10-year warrantyDFO 3-1825%More capacity1 Donaldson ToritDOwnFlO ® Oval DusT cOllecTOrsA FAmily OF Over-AchieversDFO collectors offer some strong benefits that distinguish them from all other collectors available in the market today.DFO 2-4DFO 3-3 eAsy tO use Quick-release handles provide easy cover removal and faster filter access cOmpAct Smaller footprints for applications that require maximum cleaning efficiency in even smaller spaces pOwerFul DFO collectors provide 25 percent more capacity than same-sized dust collectors cOst eFFective The proprietary ExtraLife™ Filter Cleaning System averages up to 30 percent increase in pulse cleaning energy for unmatched cleaning ability innOvAtive Unique oval-shaped Ultra-Web® cartridge filters provide the longest filter life and highest filtration efficiency—which lowers costdonaldsontorit.com | 800-365-1331 2DOwnFlO ® Oval DusT cOllecTOrsOutperFOrms All Other cOllectOrsDFO models 1-1, 2-2 and 3-3• Incorporate several exclusive and unique features• Completely self-contained, “plug-and-play” type units• Packaged with power pack, controls, silencer, damper, dust container and more• Remarkably quiet operation• Exceptionally compact design• Easily movable through standard aisles and doorwaysDFO 1-1clean-airoutletdamperdirty-air inletfiltercartridgefilteraccessfanmotornOrmAl OperAtiOns FOr mODels 1-1, 2-2 and 3-33 Donaldson ToritDOwnFlO ® Oval DusT cOllecTOrssizes & OperAtiOnsDFO models 2-4 to 4-128• 23 standard model sizes• Customized sizes available• Many options and accessories• Exceptionally compact design• Significant energy savingsnOrmAl OperAtiOns FOr mODels 2-4 tO 4-128optionalclean-airoutletclean-airplenumstandardclean-airoutletfilter cartridgesdirty-air inletSiMplycarTriDge cOllecTOrs availableThe beStdonaldsontorit.com | 800-365-1331 4DOwnFlO ® Oval DusT cOllecTOrscArtriDge Filter technOlOgyThe Downflo Oval filter design is another indication of Donaldson Torit’s commitment to technical research and development. The distinguishing factor in our filters is Ultra-Web® filtration technology. Ultra-Web nanofiber media uses a layer of fibers 0.2 to 0.3 microns in diameter to capture contaminants on the surface of the media less than one micron in size. The resulting dust cake is easily cleaned off during the automated collector cleaning cycles providing cleaner air longer, with a minimum MERV* 15 efficiency rating based on ASHRAE 52.2 - 2007 test standards.10 micronNanofiber Media(600x)nanofiber surface loading technology is available in all ultra-web and Fibra-web filter cartridges.commodity Filter Media(600x)conventional media has spaces of up to 60 µm between fibers, allowing dust to become deeply embedded.10 micronhigh perFOrmAnce FilterscArtriDge Filters FOr mAny ApplicAtiOns The Downflo WorkStation (DWS) in conjunction with Donaldson Torit’s unique oval-shaped filter cartridges are an unbeatable system.

High performance oval-shaped filters handle up to 25 percent more airflow without increasing velocities, which can cause filter abrasion. Sophisticated FLUENT®*Airflow Modeling Software revealed that oval-shaped cartridge filters have fewer areas of high velocity, resulting in a lower potential for media abrasion and increased filter life.DOWNFLO OVAL COLLECTOR 9145 cfm (15,534 m3/h)STANDARD COLLECTOR 7315 cfm (12,426 m3/h)AirFlOw breAkthrOughs leAD tO higher FiltrAtiOn eFFiciency Sophisticated computer modeling for fluid dynamics, structural mechanics and acoustics puts DFO models 1-1, 2-2, and 3-3 in a technical class all their own.

A new cabinet design with convex side walls streamlines the airflow path and increases the cabinet’s cross-sectional area. The convex side walls provide more space between filters, lower cabinet velocities and reduce the potential for media abrasion.pulse cleAning technOlOgy ExtraLife™ Filter Cleaning System uses proprietary, computer-modeled pulse cleaning technology to easily “pulse off” dust from the surface of the filter, improving filtration efficiency and prolonging filter life. The red lines in the illustration show the increased pressure at the front of the Downflo filter generated by the ExtraLife system.
