Particulate
Filters
For the removal of solid particle contaminants down to 5
microns and the separation of bulk liquids.
This type of fi lter is generally used in industrial applications
where liquid water and oil, and harmful dirt particles must be
removed from the compressed air system. This type of fi lter
should also be used as a prefi lter for the Coalescing (oil
removal) fi lter.

Operation
Wet and dirty inlet air is directed downward and outward in a
circular pattern by the turbine-shaped upper baffl e. This action
mechanically separates a large amount of the liquid and gross
particles, which then fl ow down the inside of the bowl, past
the lower baffl e, into the quiet zone to be drained away. The
quiet zone baffl e prevents the contaminants from re-entering
the air fl ow stream.
The partially cleansed air then passes through the fi lter
element. By utilizing depth fi ltration, the 5 micron fi lter media
provides superior fi ltration, exceptional
service life and minimum pressure drop.

Coalescing Filters


(Oil Removal)
Specifi cally designed for the removal of solid particles, water
and oil aerosols down to 0.01 micron. Maximum remaining
oil content of air leaving the fi lter down to 0.01ppm at 70°F
(21°C) at a pressure of 100 PSIG (6,9 bar g) using a typical
compressor lubricant. Two fi lter element grades are offered to
better meet your air quality requirements.
Grade B and B1 fi lter elements are used for most air
coalescing applications where the removal of liquid aerosols
and submicronic particles for general air quality is required.

Protection of components such as air valves, cylinders, as
well as air conveyors, air gaging, air bearings, air control
circuits and paint spraying equipment are examples of specifi c
end-use applications. This grade of fi lter element should be
used as a prefi lter for the Grade C coalescing fi lter.
Grade C high-effi ciency fi lter elements are used where the
removal of extremely fi ne particulate and virtually “oil-free” or
high quality air is necessary. Specifi c end-use applications
are protection of critical air control circuits, air logic systems,
fl ow and temperature controllers, food processing, electronics,
health care and fi lm processing. This grade of fi lter element
should be used as a prefi lter for the Grade D oil vapor removal
fi lter. 美国Wilkerson威尔克森颗粒过滤器9EM-TK-190-5现货特价

Operation
The fi lter element design utilizes a borosilicate micro fi ber
that provides superior fi ltration effi ciency, quick draining and
minimum pressure drop. Unlike standard particle fi lters, air
fl ow is inside to out. The compressed air / gas passes through
the inner layer of the fi lter element which acts as an integral
pre-fi lter to remove large contaminants. This gives protection
to the layer of high effi ciency fi lter material which substantially
removes submicronic aerosols and solids from the air fl ow
stream. Solid particles are permanently trapped within the
fi lter media.
The fi ne liquid particles, including aerosols, after initially being
trapped by the fi bers of the fi lter media, begin to collect or
coalesce forming larger droplets. These droplets, along with
other large droplets present, are pushed to the outer surface.
Here, the anti-reentrainment barrier collects the droplets
as they break free from the micro fi ber and allow them to
gravitate within its cellular structure forming a “wet band”
around the bottom of the element.
Clean fi ltered air / gas passes through the anti-reentrainment
barrier above the “wet-band” where the resistance to fl ow
is less, leaving a quiet zone of no air / gas movement in the
bottom of the fi lter housing. The separated liquid drops from
the bottom of the fi lter element and falls through the, without
being re-entrained, to the bottom of the fi lter housing where it
collects to be removed by a drain.

Oil Vapor
Filters
Activated carbon element for the removal of oil vapor and
oil associated odors. Maximum remaining oil content of air
leaving the fi lter is 0.003 ppm at 70°F (21°C) at a pressure
of 100 PSIG (6,9 bar g). For the Grade D fi lter element, two
types of designs are used depending on the size and fl ow
capacity of the fi lter housing.
An oil vapor fi lter is used, in conjunction with a Grade C fi lter
element, where the application requires very high air quality.
Typical applications are food processing and packaging,
pharmaceutical, fermentation, electronics and semi-conductor,
and critical air control.
Operation
While the Grade B, B1 and C fi lter elements can remove
extremely fi ne liquid and solid particles, they cannot remove
gaseous contaminants such as oil vapor or odors. To do this
you must employ the physical phenomena of adsorption.
Activated carbon, having an affi nity for oil vapor molecules
and with an extremely high surface area, created by its
capillary structure, is used.
Our activated carbon Grade D fi lter
elements are designed to maximize the adsorption properties
of the carbon. This is achieved by fi rst passing the air through
carbon granules located either in an annular space or tubular
section. The granules provide a very high ratio of surface
area to volume, and when arranged in a deep bed, increases
the dwell time of the air fl ow. This type of design provides the
benefi t of both high effi ciency and longer service life of the
activated carbon.

Differential Pressure Indicator
(DP2, DP8)
The Wilkerson direct mounting Differential Pressure Indicator
is equipped standard on most Coalescing Filter models. It
provides a maintenance free means of determining the service
life of the fi lter element. With a new fi lter the indicator shows
all green, and progresses to a full red indication a
7-8 PSID, indicating the element should be changed. The
magnifi ed indicator can be easily seen from the top or either
side of the fi lter, and with only one moving part will provide
reliability and long life.
The Differential Pressure Indicator cannot be retrofi tted
to Wilkerson fi lters ordered without it. It is available as a
replacement accessory kit.
Note: The maximum operating pressure for metal or plastic bowls with
this Indicator is 150 PSIG. The maximum operating temperature
is 150°F for metal bowls and 125°F for plastic bowls.
DP3 Differential Pressure Gauge
The Wilkerson direct mounting Differential Pressure Gauge
(non-pressurized face) is standard on all mainline fi lters
and it is available as an accessory in kit form. With a scale
reading to 20 PSID (1370 m bar dp) the gauge gives a quick
indication of the status of the fi lter element in the fi lter. The
gauge provides a reliable method to help ensure that the fi lter
element is changed at the most economical and convenient
time.美国Wilkerson威尔克森颗粒过滤器9EM-TK-190-5现货特价
