HF SERIES FILTERS
Complete Filter Offering
Seven grades of filtration allow systems to be
precisely customized
Each element grade is tested to
international standards
HF SERIES FILTERS
Grade 11 - Bulk Liquid Separator
A labyrinth style flow path removes liquid
water from the air stream by forcing abrupt
directional changes
Liquid water impinges on the walls of the
internal cores while the air stream flows
easily through the labyrinth, providing
minimal pressure losses
Efficient to 5% of rated flow
Removes up to 30,000 ppm liquid
contamination at efficiencies greater
than 90%
HF SERIES FILTERS
Grade 9 - Separator/Filter
99% efficient at removing up to 25,000 ppm
liquid water from an air stream
In-depth coalescing bed captures solid and
liquid contaminates 3 micron in size
and larger
HF SERIES FILTERS
Grade 7 - Air Line Filter
Coarse coalescing filter capable of providing
ISO 8573.1 class 2 solid and class 3 oil
content air
Captures and removes particles 1.0 micron
and larger in size
Remaining oil content as low as 1.0 mg/m3
Extends life of fine coalescing Filters
HF SERIES FILTERS
Grade 6 - Desiccant Afterfilter
Designed to remove solid particles down to
1.0 micron in size in a dry air flow
Long life afterfilter for heatless
desiccant dryers
Outside/in flow, extends the usable life of
the filter
HF SERIES FILTERS
Grade 5 - High Efficiency
Coalescing Oil Removal Filter
Capable of providing ISO 8573.1 class 1
Solid and Class 1 oil content air quality
Captures 99.99+% of all oil aerosols
Reduces oil aerosol content to 0.008 ppm
(0.01 mg/m3)
HF SERIES FILTERS
Grade 3 - Maximum Efficiency
Coalescing, Oil Removal Filter
Capable of providing air quality greater than
ISO 8573.1 class 1 solids and oil content
air quality
Captures 99.999+% of all oil aerosols
Reduces oil aerosol content to 0.0008 ppm
(0.001 mg/m3)
Best suited to critical applications
HF SERIES FILTERS
Grade 1 Oil Vapor Removal Filter
Capable of providing ISO 8573.1 class 1
solid and oil content air quality
Activated carbon adsorption filter
Contains 2x more carbon than supplied by
industrial activated carbon filters
Reduces oil aerosol content (as a vapor)
to 0.003 ppm

Save Energy
with HF Series Filters
Filter housing provides large flow paths
which minimizes pressure losses
The seven element grades allow for system
customization
HF SERIES FILTERS
Elements Designed to Extend
Life and Reduce Pressure Losses
Large 45% open area stainless steel cores
provide even air flow through media at
minimal pressure losses
Filter media with over 96% void volume,
lowers pressure losses while matrix blended
media increases capture efficiency
Thick filter bed extends useable life without
adding pressure losses
HF SERIES FILTERS
Reliable Differential Pressure
Gauges & Monitor Save Energy
Three available methods of Differential
pressure indication
Electronic intelligence of the Filter Monitor
Face Gauge
Slide Indicator
Changing the filter elements at the proper
time saves energy and protects the
compressed air system
Saving Energy by
Replacing Filter Elements
Reduce energy losses by knowing when
its cost effective to replace the filter
elements
Differential pressure gauges determine
the end of an element’s life. Further
contaminant loading beyond this point
greatly increases system pressure
losses
Saves money and greatly minimize
pressure losses in systems by replacing
the elements at the end of their efficient
life
Filter monitor calculates the point of
maximum element efficiency. Loading
beyond this point increases pressure to
the end of the element’s life.

Indications of Element Replacement
Limits False Maximum Pressure Warnings
Provides a count down of days starting at 60
HF SERIES FILTERS
Filter Performance Indication
of Element Replacement
Calculates the moment of optimal
element replacement
Provides a 60 day notice before reaching
the replacement point
Monitor mathematically graphs the daily
average differential pressure
Monitor compares the calculated graph to a
known performance graph for each filter to
determine the optimum point of
element replacement

Remote Alarm Capabilities
RJ11 connection on the monitor can send an
alarm signal to the relay box as far as 100 feet
away
The relay box provides dry alarm contacts to
indicate the alarm mode of the Filter Monitor
and an electronic demand drain
The relay box powers both the Filter Monitor
and the electric demand drain
