Donaldson Torit DFO 3-24 Cartridge Filter Downflow Dust Collector

DFT dust collectors’ proprietary downward airflow design delivers the highest filtration performance whilst using less energy.

The DFT collectors proprietary ExtraLife™ Filter Cleaning System, and Donaldson Torit’s cartridge filters together are an unbeatable system. 

The Donaldson Torit® Downflow (DFT), delivers optimum performance and is one of the best values available in today’s marketplace.

The DFT advantages can be found in the collector’s proprietary design and components. Featuring a ledge-less design in combination with proprietary filter media and cleaning technology.

Torit's cartridges now 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 cartridge filters, especially well-suited for filtering sub-micron dust particles, providing higher efficiency and smaller footprints than any baghouse collector or even other cartridge collectors.

DFT's adds up to long-term savings and improved performance in many applications.

DFT Offers:

  • Ledge-less construction, Eliminates dust build-up and accommodates wash down environments
  • 18 kW fan supplied with acoustic diffuser 
  • Compact design Minimises floor space.
  • Powerful performance Proprietary ExtraLife™ Filter Cleaning System provides 30% more cleaning energy
  • A Wide range of filter cartridges are available off the shelf to suit a wide range of applications from simple dust collection through to smoke and fumes from such operations as welding and laser cutting.
  • Cost savings, Fewer filter change-outs, reduced filter disposal costs, less energy usage
  • Reliability Exceptional results for over 20 years and counting
  • Easy system setup 
  • Easy maintenance

Pulse Cleaning Technology  Filter Cleaning System uses, computer-modelled pulse cleaning technology to easily “pulse off” dust from the surface of the filter, improving filtration efficiency and prolonging filter life.

A wide range of filter media's are available from the Ultra web range of cartridges allowing the DFO to be tailored to meet the exact needs of the nuisance dusts to be extracted.

Easy Maintenance, with the design of the DFT’s quick access covers, filter removal and maintenance is extremely fast with one operation.

12 paired filter cartridges (24 in total) each cartridge has a filter area of 18.5 m² (190ft²) giving an overall filter area of 444 m² (4550ft²)

This unit is capable of extracting within the range of 2,280 - 19,150 cfm dependent on the final fan selection, system resistance and dust loading.



How do Dust Extractors Work?

Dust collection systems work in a variety of different ways but all have general principles in common. They draw process dust and particulates from the air through a filter that first captures and separates the matter, and then discharges decontaminated air back into the workplace or environment.

Dust extractors are used in many different and varied industries and so different demands are made of them; however all have common components such as a blower (or fan), dust filter, filter cleaning system, dust container and dust removal system.

Five common types of dust collection equipment are fabric filter baghouses, inertial separators (like mechanical cyclones), cartridge collectors, wet scrubbers, and electrostatic precipitators.

What are Reverse Pulse Jet Dust Collectors?

Reverse Pulse Jet Dust Collectors use a jet of air to clean dust from the collector's filters. Commonly used in pleated filter cartridge units, the filters are cleaned by a series of rapid, high-pressure air jets which sends a blast or shock of air through the reverse side of the filters. In effect this shakes the collected dust from the filters into the dust collection system. The rapid reverse pulse of air allows for continuous operation with the fan running and has high collection efficiencies.

Reverse Pulse Jet Dust Collectors are the most common type of industrial dust collectors and can handle a wide range of temperatures and pressures. They are commonly used in manufacturing environments where large volumes of solids are processed, such as mineral production, food processing and metal fabrication industries.

A control unit sets the variables such as time duration between pulses, length of pulse and pressure. 

What are Cartridge Dust Collectors?

Cartridge Dust Collectors a type of filter unit which is predominantly used in environments where space is at a premium. They can often maintain airflows which remain comparable to larger baghouse units.

Cartridge units provide larger fabric filter areas into a smaller place, use less filters and can be changed from the outside of the extractor, rather than having to access the unit internally, thus reducing filter replacement times and less environmental contamination issues for maintenance staff.

They are ideal for commercial and industrial environments, whose processes produce very fine-to- moderate dust-like powders, metalworking, woodworking, fume collection, thermal spraying, among other processes.
