Downflo Evolution Dust Collectors

From the Originators of the Cartridge Collector

The breakthrough performance of the Downflo® Evolution (DFE) family of cartridge dust collectors is the result of Donaldson relentless drive to improve its products and exceed customer expectations. Donaldson Torit put decades of industry experience to work to produce a new, best-in-class dust collector capable of reducing equipment size and number of required filters by up to 40% compared to a typical cartridge collector. A smaller collector helps lower the initial purchase price, reduces filter costs, and opens up valuable manufacturing floor space.

This state of the art collector, coupled with Donaldson’s industry-leading Ultra-Web® nanofiber filtration technology, delivers a significantly smaller equipment footprint with up to 40% fewer filters required, reducing maintenance time and overall cost of operation.​

ENGINEERED AIRFLOW MANAGEMENT

The DFE's game-changing dust collection performance is achieved through a combination of design features that result in significant customer benefits.

        • Pre-separation of heavy dust particles

        • Lower pressure loss than baffle design used by
          competitors

        • Minimal filter element abrasion

HIGH PERFORMANCE FILTERS

The DFE 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 fine fibre media uses a layer of fibres 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.

TRIAGONAL FILTER SHAPE

The ultimate goal of any pulse-cleaned dust collector is to remove the contaminant from the airstream and get the contaminant into a containment vessel under the equipment's hopper. The DFE's unique shape positions more filter media at the bottom of the cartridge element so pulse-cleaning energy directs the ejected dust toward its ultimate destination - the containment vessell.
