Donaldson Torit DF0 4-56 Downflow Oval Dust Collector 

** Has been professionally decommissioned by Donaldson Torit in 2020. Please see their decommissioning report attached **

The DFO advantage is found in the collector’s proprietary design and components. The combination of a new cabinet design that greatly lowers cabinet velocities, proprietary Extra-Life™ cleaning technology, and proven Ultra-Web fine fibre filters allows more airflow through the collector without increasing the size of the footprint or damaging the filters.
A smaller collector helps lower the initial purchase price, reduces filter replacement costs and opens up valuable manufacturing floor space.

Twin Heavy Duty Cyclones on Inlet, originally serving High Inlet Gas Temperatures via ex. Induction Melting Plant. Designed to deal with heavy dust loading's at high temperatures before the cartridge filter, therefore extending the life of the cartridges by cooling the gas streams.

DFO Features:
⦁ Lower initial cost per cubic foot of air per minute
⦁ Higher efficiency—cleaner air
⦁ Lower pressure drop— greater energy savings
⦁ Fewer filter changeouts
⦁ Reduced filter disposal cost
⦁ Easy system setup
⦁ Less maintenance

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 percent more capacity than same-sized dust collectors
Cost effective
The proprietary ExtraLife™ Filter Cleaning System averages up to 30 percent 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

High Performance Filters
The Downflo Oval 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 fiber media uses a layer of fibers 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.

Unique oval shape contributes to higher airflow capacity
The Downflo Oval filter design is a reflection of Donaldson Torit’s commitment to technical research and development. High performance oval-shaped filters handle up to 25 percent 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.

Convex side walls
Technical discoveries improve filtration performance and prolonged filter life. A new cabinet design with convex side walls streamlines the airflow path and increases the cabinet’s cross-sectional area. The convex side walls provide more space between filters, lower cabinet velocities and reduce the potential for media abrasion.

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.
