Donaldson Downflo® Series Dust Collectors

Smaller Footprint, Smarter Operation

Donaldson Downflo® Series dust collectors offer higher-efficiency dust collection in a smaller footprint & a lower cost of ownership than all the competition.

Downflo® Evolution - DFE Dust Collectors

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.

Smaller Footprint

This smaller collector helps lower the initial purchase price, reduces filter replacement costs and opens up valuable manufacturing floor space.

Fewer Filter Changes

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

Revolutionary Airflow Management

The revolutionary Airflow Management directs incoming air to an intelligent dropout zone for reduced filter loading. This game-changing dust collection performance is achieved through a combination of design features that result in significant customer benefits.

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.

This proprietary pulse-shaping design distributes the cleaning energy evenly to match the unique shape of the filters providing more effective cleaning of the filtration media which results in increased airflow capacities through the dust collection equipment.

Durable Construction

Durable construction and reliable operation for maximized production uptime.

Features & Benefits:

Clean Aesthetics

Strong and durable 10/12 gauge, all-welded Packaged Downflo Evolution dust collectors feature modern, clean lines to complement state-of-the-art manufacturing environments and are ideal for integration into OEM designs and a variety of applications.

Easy Service

Tool-free, hinged access doors allow simple, quick filter changeouts.

Easy Dust Disposal

Wheeled bins, available in two different sizes, make dust clean up simple and easy.

Downward Airflow Advantage

EPA-sponsored research has shown that “superior performance results from the downward flow of the dirty airstream, reducing re-deposition of dust onto filter packs.” The Donaldson Packaged Downflo Evolution supports dust and fume control on continuous duty applications.

Downflo® Oval - DFO Dust Collectors

Proven Design Delivers Value & Performance

The Donaldson Torit® Downflo® Oval cartridge dust and fume collector sets the standard for industrial dust collection – by providing a 25% increase in airflow capacity, improved airflow path, and a 29% increase in pulse cleaning pressure. These compact, high-efficiency units use high efficiency oval-shaped cartridge filters, especially well-suited for filtering the sub-micron dust.

A Family of Over-Achievers

The high-performance Downflo Oval (DFO) family of dust collectors provides up to 25% more filtration capacity than other same-sized cartridge collectors. Powered by proprietary Ultra-Web® fine fiber filtration technology, DFO delivers cleaner air, up to two times longer filter life, and greater cost savings.

A smaller collector helps lower the initial purchase price, reduces filter replacement costs and opens up valuable manufacturing floor space.

DFO Features & Benefits

  • Lower initial cost per cubic meter of air per hour (m3/h) / cubic foot of air per minute (cfm)
  • Higher efficiency—cleaner air
  • Lower pressure drop—greater energy savings
  • Fewer filter changeouts
  • Reduced filter disposal cost
  • Easy system setup
  • Less maintenance

Outperforms Other Collectors

The DFO collectors offer some strong 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.


Smaller footprints for applications that require maximum cleaning efficiency in even smaller spaces.

DFO collectors provide 25% more capacity than same-sized dust collectors.


The proprietary ExtraLife Filter Cleaning System averages up to 30% increase in pulse cleaning energy for unmatched cleaning ability.


Unique oval-shaped Ultra-Web cartridge filters provide the longest filter life and highest filtration efficiency—which lowers cost.
The Unique Oval Shape Contributes to Higher Airflow Capacity able to handle up to 25% 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® Workstation - DWST

Downflo® WorkStations (DWST) fit anywhere on the plant floor and apply NO restrictions to worker movements or visibility. The full line of WorkStations is designed specifically for those in-plant areas where dirty and/or noisy operations are out-in-the-open, like grinding, sanding, chipping, batch mixing or welding.​​​​​​​​​​​​​​​​​​​​

The Downflo WorkStation’s advantages are found in the collector’s exclusive design and proprietary components. Featuring a ledgeless design in combination with proprietary Ultra-Web® filter media, the DWST delivers exceptional performance in metalworking, woodworking, and process applications where high filtration efficiency and ledgeless construction are required.

DWST Features & Benefits

  • Flexible, Modular, Self-Contained Workstations
  • Energy savings – recirculate clean air and reduce the need for costly make-up air
  • Proprietary Ultra-Web cartridge filters provide cleaner air longer
  • Ledgeless construction minimizes dust build up inside the collector
