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

HF SERIES FILTERS

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

HF SERIES FILTERS

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.

HF SERIES FILTERS

The Filter Monitor Evaluates:

Differential Pressure

Time based

Filter performance

HF SERIES FILTERS

Differential Pressure and Time-Based 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

HF SERIES FILTERS

Communicating with the Filter Monitor

All programming equipment is onboard

Uses (3) standard AA batteries for

simple maintenance

HF SERIES FILTERS

Filter Monitor Communication with the User

Provides instantaneous differential

pressure values

Provides daily average differential

pressure values

Provides a 60 day warning of impending

element replacement

HF SERIES FILTERS

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
