The breakthrough performance of the Downflo® Evolution (DFE) family of cartridge dust collectors is the result of Donaldson Torit’s 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 replacement 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.

DFE Collector

Revolutionary Airflow Management

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



MaxPulse Cleaning System

Breakthrough Filter Cleaning

The DFE provides breakthrough cleaning performance resulting in improved filtration capacity without sacrificing filter life or taxing compressed air consumption.

The MaxPulse™ Cleaning System delivers 27% more cleaning energy to filtration media. This minimizes energy losses by focusing on the cleaning air’s exact path and delivers uniform cleaning energy to all effective filtration media. Donaldson Torit’s proprietary, pulse-shaping design distributes the cleaning energy evenly to match the unique shape of the filter.

More effective cleaning of the filtration media results in increased airflow capacities through Donaldson Torit dust
collection equipment.


DFE Cartridge Filter

Industry-Leading Filtration Design

The DFE filter design is another indication of Donaldson Torit’s commitment to technical research and development.

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 vessel!

25% Round

Traditional Round Filter

27% Triagonal Filter

The DFE triagonal filter features more filter media at the bottom of the cartridge element than any other cartridge on the market.
