Downflo WorkStation
Outperforms All Other Collectors
The high performance Downflo® Oval family of over-achieving dust collectors is the best
value available. A natural extension to the DFO family, Downflo WorkStations (DWS) are
based on the same value proposition and provide more filtration capacity than other samesized dust collectors. Downflo WorkStations are extremely versatile and add up to longterm savings, better performance, and maximum productivity.
The Downflo WorkStation’s advantage is found in the collector’s exclusive design and
patented components. Featuring a ledgeless design in combination with patented
Ultra-Web® filter media and cleaning technology, the DWS delivers exceptional
performance in metalworking applications, wood applications, and process applications
where high filtration efficiency and ledgeless construction is often a requirement.
Downflo WorkStations 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—grinding,
sanding, chipping, batch mixing or welding.
DWS Offers:
• Flexible, modular Self-contained workstations.
• Innovative Unique oval-shaped UltraWeb® cartridge filters provide higher
filtration efficiency and longer filter life.
• Quick and easy
Requires no tools.

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.

Engineered for Reliable Performance
Downflo WorkStation Booth Packs are a reflection of Donaldson Torit’s
commitment to technical research and development. Sophisticated FLUENT®* airflow
modeling software revealed that DWS booth packs are designed for adequate and consistent
capture velocities at the booth opening and throughout the booth. No system imbalance, no
air turbulence, no hot spots, no uncomfortable draft inside the booth that can upset working
conditions.
FLUENT® Airflow Booth Modeling
DWS Booths Are Designed to remove fine airborne contaminants from the
workers’ breathing zone and provide a cleaner working environment in metalworking,
woodworking, and process applications.

Cartridge Filter Technology
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 Ultra-Web® and Fibra-Web® filters is nanofiber filtration
technology. Ultra-Web nanofiber 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,
ensuring highest filtration efficiency and longest filter life.
Nanofiber Media
Commodity Filter Media

micron
600X
600X
Nanofiber technology is available in all Ultra-Web
and Fibra-Web filter cartridges.
Conventional media has spaces of up to 60 microns
between fibers, allowing dust to become deeply
embedded.
DFO Filter Media Pleats Shorter and stiffer filter pleats help minimize dust
entrapment and simplify filter cleaning. By reducing the height of the filter pleats from the
standard 2 inches to 1.5 inches, the pleat wall is less likely to collapse or bend, which can
encapsulate dust and prevent its expulsion.

Cartridge Filters for Many Applications The Downflo
WorkStations in conjunction with Donaldson Torit’s unique oval-shaped filter cartridges
are an unbeatable system. Choose from our superior line of filters to complete the most
powerful filtration solution available for your application.
