Description
Designed for versatility, the WSO (Water, Smoke,
and Oil) mist collector is specifically engineered for
water-soluble, smoke, and oil-based mist
applications. WSO mist collector, Machine-
Mountable Models WSO 10, 15, and 20 collect
airborne mist such as oil, water-soluble, semi-
synthetic and synthetic coolant from machining
operations. Two stages of filtration, plus an
optional HEPA or 95% DOP filter, provide a
cleaner, healthier work environment as well as a
more cost effective means of mist collection. With
airflow capacities up to 1200 cfm for the WSO 10,
15, and 20, the WSO is a strategic component to
meeting industrial and government air-quality
standards. The high efficiency filter cartridges allow
air and coolants to be recycled.
Designed to increase the versatility of the unit, a
variety of filter media specifically designed for mist
collection is a standard offering on the product line.
The WSO model number (10, 15, or 20) indicates
the height of the primary filter in inches for that
particular model. For examples, the WSO 15
contains a 15 inch tall primary filter. The primary
filter is uniquely designed for either water-based
coolants, straight oils, or thermally-generated
smoky applications. Standard options include drain
collection containers, P-traps, adjustable floor
mounting stands, and afterfilters.
The WSO machine-mountable unit is powered by a
blower and motor mounted in the filter cabinet.
Purpose and Intended Use
Airborne mist is small droplets of metalworking
fluids suspended in the air. Metalworking fluids
include straight oils, water-soluble coolants, semi-
synthetic and synthetic coolants. These fluids
perform a variety of functions such as lubricating or
cooling the part or the tool, flushing chips away
from the part, and suppressing dust and smoke.
Mist is created in two ways: mechanical action or
thermal effects. Mechanical action involves coolant
used for light lubrication and generally creates mist
greater than one micron in size. Thermal effects
occur when heat vaporizes the coolant, the vapor
cools and recondenses into a mist. Thermal effects
create mist from 0.01 to 1 micron in size. Other
contaminants, such as dust from the part or the
tool or smoke from the vaporization of the oil or
coolant are also generated when using
metalworking fluids.
The WSO mist collector is not designed to handle
water mist alone. There should be some type of oil
content to allow coalescing since water vapor will
simply pass through the filters. The extremes of
very heavy oil and light, thin oil should be avoided.
Very heavy oil, similar to tar consistency, will not
drain while very light, thin oil, similar to paint
thinner consistency, may evaporate.
