Description
The Downflo II dust collector is a continuous-duty,
modular collector with cartridge-style filters. The
downward airflow design delivers high filtration
efficiency while using less energy. Continuous-duty
means no downtime. The filters are pulse-cleaned in
sequence, one set at a time, without turning the unit
off. The modular design allows flexibility in system
design and adapts easily to limited space areas. Each
standard module is two or three filter rows wide by
two, three, or four rows high by two filters deep.
Designed to increase the versatility of the unit,
standard options include top or front inlets, filter
access covers, Bag Out, cold climate kits, steep-slope
ledge-free hoppers, trough hoppers, and stationary
service platforms.
Purpose and Intended Use
Downflo II collectors are widely used on nuisance
dust where the load to the collector is less than two
grains per cubic foot. Some typical applications
include abrasive blasting, grinding, mixing,
blending, processing, pan coating, powder paint
applications, sand handling, welding, and
machining. Each application is different and
selecting the correct filter cartridge for the
application and type of dust collected is important.
For all ambient, extremely fine, and non-fibrous
dust, use Ultra Web
®
filter cartridges which offer
high efficiency and performance on fine
particulate.
For fibrous dust, use a cartridge with an open-
pleat design, such as Fibra-Web
®
.
Operations involving high temperature and high
humidity may require special attention.
Temperature, moisture content, and chemistry
issues may require custom collector design.
Appropriate cartridge options are available from
Donaldson Torit.
Hygroscopic dust such as fertilizer, salt, and
sugar should be handled under a controlled, low
humidity environment. Contact Donaldson Torit
for filter cartridge selection.
Flammable or explosive dust may require
custom collector design options and special
cartridges. Contact Donaldson Torit for design
assistance.
Applications with high hydrocarbon or high oil
content may require special treatment or filter
media.
CAUTION!
Misuse or modification of this
equipment may result in personal injury.
Do not misuse or modify.
