Donaldson Company, Inc.
The Downo WorkStation (DWST), is a continuous duty, self contained, modular workstation with cartridge style lters. Continuous
duty means the lters can be pulse cleaned on-line without interrupting airow through the collector. The lters are pulse-cleaned
in sequence, one at a time, without turning the collector off. The modular design creates a custom collector for each application.
The DWST power module includes a blower, two (2) dust drawers (available in either metal or plastic), a louver air inlet that can be
located in a high or low position, and a ledge less design to reduce dust build up in the collector. Models DWST 4-1, 4-2, 4-3, 4-4,
and DWST 6-1, 6-2, 6-3, 6-4 power modules can have joining strips to tie modules together.
Optional booths can be applied for all models. Designed to increase versatility of the collector, standard options include heavy duty
wall and ceiling acoustic panels. They also include a ceiling light for each power module on hard sided and roof booths in dust
tight or ush mounting lighting. Soft side weld and acoustical curtain booths are also available with a clear plastic ceiling to allow
plant light to illuminate the booth. Also, a moveable side shield with canopy booth is available for one module and two module
congurations.
Intended Use
The DWST is commonly installed in applications where dust containment from a specic operation is required. Typical applications
include; abrasive blasting, batch mixing and grinding.
While the DWST effectively contains dust generated within the work area, it does not provide source capture of dust and some
noise will be emitted from the booth. The 200 fpm indraft velocity produced by each power module is generally sufcient to prevent
nuisance dust from escaping the DWST.
Abrasive Blasting
Abrasion-resistant options include an open louver inlet and smooth wall booth. Recommended options include: a control panel
for reduced installation expense, ush lights for increased headroom, and ASHRAE or HEPA afterlters to monitor primary lter
performance for added safety on hazardous dust.
Batch Mixing
Dumping and mixing operations often produce signicant amounts of nuisance or hazardous dust. The DWST provides effective
dust control and allows complete freedom of movement. ASHRAE or HEPA afterlters can be added to monitor primary lter
performance for added safety on hazardous dust.
Grinding
The DWST gives the worker complete freedom of movement while grinding or moving around large or odd-shaped parts. Open-

lters are required for the brous nature of composite dust. Recommended options include acoustic
panels for a quieter work environment, control panel for reduced installation expense, ush lights for increased headroom, and
HEPA afterlters to monitor primary lter performance for added condence on composite dust and for hazardous dust such as
chromium, cadmium, and zinc.
