Wood Dust:
Air Moves Dust!---This Fact can be
a Problem
At Industrial Maid we use it to Design a Solution
Industrial Maid's
AZTECH Model T 3000 modular ambient
industrial air cleaning units with cabinets fabricated from
recycled polyethylene plastic (material from used pop
bottles and milk jugs). The black matte finish looks
terrific, resists dents and scratches and meets all NFPA
fire codes. The benefits are important to the consumer as
well as the environment because our units are
lighter, dampen blower noise and are less expensive than comparable equipment
manufactured with carbon steel cabinets. The unique systems
are completely modular, so additional cabinets can be added
for more sq. ft of filter media and to accommodate air flow
rates of 3,000 to 7,500 cfm.

FILTER WALLS
& ENVIRONMENTAL BOOTHS |
Model FW35-4
Industrial
Maid announces the new addition of a
“side draft” filter wall unit for use in
industrial manufacturing plants to
contain welding smoke & fumes, grinding
dusts, vapors and other air borne
contaminants. This unit is mounted on a
steel pallet with fork lift slips,
offers three stages of filtration – 1)
2” polyester pre-filter or 2” spark
baffle filter – 2) 4” pleated filter &
3) 45% to 95% multi pocket bag filter.
The system has a cabinet manufactured
from high density polyethylene plastic –
making it lighter, quieter,
non-corrosive and environmentally
friendly versus a steel cabinet system.
The unit runs on low horsepower ratings,
uses low air to cloth ratios and
requires no compressed air or control
boards for operation. The maintenance
is fast and simple – access thru the
front or an option is available for rear
access doors and no tools are required.
The units offer business and industry a
“lower cost of ownership” as compared to
existing technologies.
Model FW35-4 w/Environmental
Booth
Industrial Maid has designed a unique
environmental control booth to help
contain fugitive dust in the industrial
workplace. The system incorporates a
three stage media style filtration
system, powered by a totally enclosed
motor and belt drive blower package.
Three standard sizes are available - 6”
width, 10’ width and 20’ width. The
booth housing is modular in design with
acoustical sound control. The air
filtration module has fork lift slips
and an airflow range from 4,500 to
15,000 CFM. As with other IM LLC
equipment, the outer cabinet shell is
manufactured using a recycled
polyethylene plastic, making it lighter,
quieter, less expensive and more
environmentally friendly than a typical
carbon steel cabinet. The booth systems
do not require use of compressed air and
have a lower energy consumption rate as
compared to similar cartridge style
units.
Model EB56 MOD
Industrial
Maid
introduces the new Model
EB56 series packaged air filtration
unit. This system is designed to handle
welding smoke and fumes, grinding dust
and other airborne particulates. The
powerful 4500 CFM, 5 HP motor with a
direct drive high pressure BI composite
blower makes the system quiet, efficient
and easy to service. The air passes
through a spark baffle for arrestance,
then moves through a plenum chamber to
eliminate heavy particles, then lastly
passes thru a Merv 7 and Merv 14 series
of filters. A HEPA final filter is also
available to meet hexavalent chromium
fume standards for stainless steel
welding.

Problem:
Woodworking produces large quantities of both
fine, respirable dust and non-respirable
particles.
Wood dust or sawdust is a
well documented concern no
matter how large or small
your woodworking
application. Wood dust has
been officially identified
as a particulate airborne
contaminant. In any area
where woodworking is going
on, shavings and dust from
the process can have serious
health and fire
consequences.
Owners of
wood shops need to be aware
that wood dust has been
listed by OSHA (Occupational
Safety and Health
Administration as an identified
hazard for both the
immediate safety and the
long term health of workers
exposed to wood dust.
Industrial dust collection
systems are an invaluable
tool for controlling wood
dust. Health issues caused by the
irritating effect of wood
dust exposure on the
sinuses, skin and lungs make
it important for employers
to read and understand the
standards set by OSHA when
considering industrial dust
collection systems.
As, a side note, although
health and safety are
usually the primary reasons for
installing dust
collection systems, there
are other reasons woodshop
owners are interested in
addressing wood dust:
(1)Fire hazard potential
created by wood burns and
cutting. Heavy
concentrations of
powder-like wood dust in the
air when exposed to a spark
can cause an explosion very
similar to the types seen in
grain silos. (2)Wood dust
that is suspended in the air
can settle onto finished
smooth surfaces causing
imperfections in final
product. (3)All woodworkers
are well aware of the damage
wood dust can do to the
motors of the equipment and
power tools that are so
important to their work.
Industrial dust collectors
are specifically designed to
remove particulate airborne
contaminants at the source.
Engineering
controls and personal protective
equipment are two methods used for
controlling wood dust exposure.
Engineering controls, the preferred
approach, typically includes an
exhaust ventilation system with
collectors placed at points where
dust is produced, typically
ambient air cleaners
or
on a larger scale
filter walls.
Ventilation
is one of the most important
engineering controls available to
the industrial hygienist for
improving or maintaining the quality
of the air in the occupational work
environment. Broadly defined,
ventilation is a method of
controlling the environment with air
flow.
When considering methods of
control, it is important to consider
the nature of the dust and the
forces that influence its movement.
Course dust is carried by its own
momentum and usually collects around
the point of generation. Respirable
dust quickly loses its momentum and
is carried away in air currents
making capture more difficult. The
movement of machine parts such as
cutters, revolving drums, driving
pulleys, belts etc will create
considerable air movements and an
efficient extraction system should
be designed to use these air
movements to maximum advantage.
Finally, be sure
to consider these factors
when putting together a plan
for wood dust collection in
your workshop:
-
Calculate how much air
movement is required to
effectively control the
amount of wood dust
created by your
processes. This is
measured in
CFM (cubic feet per
minute).
-
The importance of design
for maximizing the
efficiency of the system
of industrial air
cleaner chosen.
That means factoring in
air flow, shop equipment
and tools, existing
ductwork and the
location of the dust
collector.
-
Determining whether a
single or double
collection system is
best for your particular
application.
Sometimes it seems as if
there are an overwhelming
number of elements to
consider when thinking about
how to provide a workspace
that is safe for your
workers and most cost
effective for your business.

questions or offer design
advice give us a call at

Because we manufacture all
of the equipment you see on
our site - no one knows it
better than we do.
(Note: All wood dust
collection systems should
have copper wire for
grounding because of
collection of dust naturally creates a
static electrical charge.)
Solution: Designing the layout
of the right system
to insure the most efficient capture of wood
dust.
