Engineered for Reliable Performance
The 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’s marketplace. 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 a ledgeless 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 generates interest and respect in process applications where ledgeless construction is often a requirement. Providing higher efficiency and smaller footprints than any baghouse collector or even other cartridge collectors, DFT adds up to long-term savings and improved performance in many applications.
Eliminates dust build-up and accommodates wash down environments.

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. The blue line shows the pulse signature of a standard cartridge collector.
