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.?

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. 美國Wilkerson威爾克森顆粒過濾器9EM-TK-190-5現貨特價

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.美國Wilkerson威爾克森顆粒過濾器9EM-TK-190-5現貨特價
