A Family Of Over-Achievers The high performance Downflo® Oval (DFO) family of over-achieving dust collectors is the best value available. Providing up to 25 percent more filtration capacity than same-sized cartridge collectors, DFO adds up to long-term savings and better performance. The DFO advantage is found in the collector′ s patented design and components. Proprietary, ultra efficient filter media and cleaning technology allow 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 (cfm)
• Long-term energy savings
• Fewer filter changeouts
• Reduced filter disposal cost
• Easy system set-up
• Less maintenance
• 10-year warranty  
Outperforms All Other Collectors The full line of DFO collectors offer a variety of benefits that distinguish them from all other collectors available in the market today. • 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 patented 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 cost Sizes & Operations

• Remarkably quiet operation
• Exceptionally compact design
• Easily movable through standard aisles and doorways DFO Technology Unfolds The Remarkable Story of DFO Begins with the Oval Cartridge Filter Itself Ultra-Web Nanofiber MediaA dramatic departure from traditional circular-shaped cartridge filters, DFO′ s oval-shaped filters, in conjunction with our patented nanofiber filter media, trap more dust on the surface of the filter than conventional commodity types of filter media such as depth-loading cellulose, polyester or cellulose/polyester blend. 
The Innovation Continues with DFO′ s Shorter, Stiffer Filter Pleats DFO Filter Media PleatsShorter and stiffer filter pleats help minimize dust entrapment and simplify filter cleaning. By reducing the height of the filter pleats from the standard 2 inches to 1.5 inches, the pleat wall is less likely to collapse or bend, which can encapsulate dust and prevent its expulsion.
