Filters – Micron Ratings

Understanding Micron Ratings for Filters

When comparing filters you may notice that some brands use micron ratings to measure the performance of their

filters and compare them with other brands. But these numbers can easily be manipulated and are not a reliable

means of measuring performance. For this reason, micron ratings are not recognized by industry technical groups

such as the Society of Automotive Engineers (SAE) or the National Fluid Power Association (NFPA).

How the test is conducted

Many filter brands base their marketing efforts on what is known as the ‘multipass test.’ In this ISO 16889 test,

artificial contaminants are inserted upstream of the filter until a specified drop in pressure occurs. Particles are

electronically counted before and after the filter to determine what percentage were captured by the filter.

What the numbers mean

The results of the multipass test are expressed in what is called a Beta ratio (illustrated above). The size (in microns)

of the particles being counted appears as a subscript number (5 for the example on the left). The pre-filter particle

count (2000) is divided by the post-filter count (1000). And the product (2) is the Beta ratio. This means that the

filter captured half of the 5-micron particles that entered it.

Nominal vs absolute

Companies who use micron ratings may choose to cite one or both of two numbers: a nominal rating and an absolute

rating. The nominal rating is usually the particle size (5 in the example above) for which the filter provides 50%

removal, or a ratio of ‘2’. The absolute rating in this example is equal to the particle size for which the filter

provides 98.7% removal, or a ratio of 75.

Filters – Micron Ratings

Ratio vs percent efficiency

A major difference in Beta ratio (75 compared to 200, for example) does not translate into a major improvement in

efficiency. A Beta ratio of 200 equals an efficiency rating of 99.5% – only 0.8% better than a Beta ratio of 75.

This difference is so minor that it could be accounted for by a minor variance in test procedures.

What really counts

Since micron ratings can be misleading, it is wise not to take them at face value. Instead take into consideration more

important factors affecting filter performance.

Structural integrity and quality control

Multipass testing tells you nothing about how a filter will hold up and perform in real working conditions. No matter

how well it tests in the lab, a filter with poor structural integrity or a manufacturing defect may fail in your machine

and cause damage.

Conventional filter assembly techniques are susceptible to inconsistencies, which can, in turn, lead to leaks or

metallic process contamination. Caterpillar filters are ruggedly designed, and the company employs automated

assembly and strict quality control measures to minimize variation from part to part.

Real-world results

Caterpillar is working with the industry to develop tests which better resemble actual working conditions. You can

find a discussion of such a test in the brochure “Keeping It Clean” (PEDP9127). Until such tests see common usage,

though, filters should be judged by their quality and consistency of performance in the field.

Air Filter Upgrade Options

Improve filtration efficiency early for better, longer engine protection

● Reduced engine wear. Particles collect on the filter’s very fine fiber surface layer, quickly building a cake that

allows less dust to reach the engine.

● Higher efficiency. This surface particle cake is more porous than dust-coated media fibers, causing less

restriction throughout filter life.

● Better engine performance and fuel economy. Low filter restriction allows the engine to “breathe” easier,

so it takes less power to pull in air.

● Longer filter life. The unique surface lasts twice as long as standard media, limiting filter changes and the

chance of contamination during service.

More efficient early, more efficient overall

Filter manufacturers often say “dirty” filters are more efficient than new ones because dust cake buildup on the

surface actually increases filtration. Designed with this concept in mind, Ultra High Efficiency Filters feature a

unique media with a very fine fiber surface layer to improve filtration efficiency early. Here’s how they work:

● Fine particles immediately cake on the surface, quickly making the filter very efficient. Less dust gets to the

engine – improving fuel economy while reducing wear and maintenance costs.

● Surface particle cake is more porous than dust-coated media, causing less restriction over filter life to improve

capacity, engine performance, and fuel economy. (In tests, restriction to air flow through Ultra High Efficiency

Filter media increased at a lower rate than five other major brands).

● Because particles get trapped in the build-up on the surface of Ultra High Efficiency Filters, the media stay

permeable longer – unlike filters with standard media, which become dust-filled deep inside. That extends filter

life and filtration efficiency two to three times that of standard media.

Twice the life in fine dust or heavy carbon environments

Ultra High Efficiency Filters work best in applications where extremely fine dust particles make up a high

percentage of the contaminant in the atmosphere or in operating conditions with high amounts of exhaust soot,

which tends to plug normal filters at low hours. To find out if Ultra High Efficiency Filters are right for your

application, please stop by soon, give us a call, or visit the Caterpillar website (www.cat.com).

Function of Breathers

Breathers are an important part of any professional contamination control strategy. As the volume of liquid changes

inside a container (e.g., a hydraulic tank), air must enter and exit the container in order to prevent the container from

becoming over-pressurized or in vacuum. Without a breather the exchange of air as it enters and exits tanks

introduces air borne contaminants.

Not filtering small air-borne particles results in:

● Pre-mature component replacement

● Lower productivity

● More frequent filter changes

Use of Breathers

Track-type tractors, stationary engines (industrial, marine, gen sets), motor graders, and Challenger® agriculture

tractors are a few product families that have breathers installed on production fuel tanks, hydraulic systems, and

gear boxes. Utilizing breathers in order to improve system performance on Caterpillar® production equipment is

expanding. To improve existing fluid system contamination control, Caterpillar is providing retrofit breathers for

field installation on Cat equipment and other manufacturer’s equipment.

Advantage of a Breather

In general, small particles cause abrasive wear on components and larger particles tend to cause sudden breakdowns

by clogging pathways or creating interference between components. Usually, a breather is much less expensive than

a filter, and its use can increase the service interval for the filter. In systems where air is forced out through the

breather, such as in hydraulic or fast fill applications, the dirt is blown out of the element, thereby increasing its life.

Breather Selection

The level of breather filtration required in a system depends on the application. The more sensitive to contamination

the system is, the greater the need for filtration.

General Rule of Thumb

● Efficiency – Higher breather efficiencies will maintain a cleaner system.

● Restriction – If air flow capacity is in question, use the larger breather.

● Location – When choosing the location for the breather, make sure that it is as convenient as possible to inspect

and change: good clearance and visual line.

● Change intervals – Breather change interval can vary widely depending on extremes in operating conditions.

As a general rule, change breathers with every fluid change or when breather vent slots appear clogged.

● Inspection – Include visual inspection of breathers in routine maintenance inspections. If in doubt, change the

breather. The cost of a new breather is minimal in comparison to the potential downstream costs of not changing it.

Reserve dirt-holding capacity

Although higher-efficiency filters accumulate dirt more quickly than Standard Efficiency filters, Cat Advanced

Efficiency Engine Oil filters do not require a shortened change interval. They feature a reserve dirt holding capacity,

which compensates for the majority of dirt accumulation increase, letting customers maintain standard change

intervals. The relative dirt holding capacity of Advanced and Standard Efficiency filters are illustrated in the

graph below.

Installation of 2P-4005 Lube Filter on 3500 Series Engines

Proper installation of the 2P-4005 Engine Oil Filter Assembly is necessary to ensure proper functioning of the filter.

If the filter is not tightened adequately, vibration that occurs during operation can loosen the filter. A loosened filter

will allow engine oil to leak. Downtime is required for the correction of any leak. A leak that is not corrected in a

timely manner or a major leak can result in significant damage from inadequate lubrication.

Note: All types of spin-on filters depend on correct tightening in order to avoid subsequent loosening. Always follow

the proper installation procedures that are illustrated on the filters.

Use the following procedure to install the 2P-4005 Engine Oil Filter Assembly. The procedure is applicable to the

old design and to the new design.

1. Clean the sealing surface of the mounting base. Ensure that all of the old filter gasket is removed.

2. Apply clean engine oil to the new filter gasket.

3. Install the filter. Tighten the filter until the filter gasket contacts the mounting base. Observe one of the index

marks on the filter and tighten the filter for an additional one full turn (360 degrees).

Note: The additional one full turn (360 degrees) is the minimum requirement for installation.

The filter can be tightened beyond the minimum one full turn for a 1/8 turn (45 degrees) further. The filter will not be

damaged by tightening for a total of 1 and 1/8 turns (405 degrees) after the filter gasket initially contacts the

mounting base.

A 185-3630 Strap Wrench can be used to perform the tightening. Use the strap wrench near the filter’s threaded end

in order to reduce the possibility of damage to the threads on the filter and on the stud.

Fuel Spin-On Filter Options

Maximum protection for fuel injectors

Higher pressures and closer tolerances make today’s fuel injectors, pumps and components more susceptible than ever

to wear and damage from contaminants. Cat High Efficiency Fuel Filters fight fuel contamination more effectively

than standard fuel filters. The critical component is a super-fine filtration media that removes more than 98 percent

of particles 2 microns and larger. By comparison, standard filters only capture particles 15 microns and larger.

● Maximum engine performance and fuel economy

● Reduced exposure to abrasives

● Reduced wear on injectors and pumps

● Fewer fuel system adjustments

● Easier starting

● Longer filter life

Take a closer look at protection and performance

The most controllable contaminants are abrasive particulates, which can vary greatly in size, hardness and abrasion.

The comparison illustrated here demonstrates the very tight clearances in your fuel system and the size of visible

particles. As you can see, even particles that aren’t visible can wear away at your fuel system and reduce performance.

A close look at Cat High Efficiency Fuel Filters shows why they’re your best choice to meet today’s fuel contamination

challenges. These exclusive filters are engineered and built to remove more contaminants, so they provide maximum

protection of injectors, pumps and other fuel system components. Make a feature-by-feature comparison of Cat High

Efficiency Fuel Filters with fuel filters from other manufacturers. You’ll soon see the higher value.

Stop contamination before it stops you

Contaminants can be as abrasive as the materials used to machine parts in the manufacturing process, so it’s

important to remove as many contaminants as possible before the fuel reaches critical components. Fuel system

contaminants are known to cause premature injector wear, reduce component life, reduce performance and cause

sudden injector seizure. Abrasive contaminants of only 5-10 microns and larger can damage injectors by breaking

down the fluid film between moving parts and eventually scratching injector plungers and barrels, causing metal-to-

metal contact and injector seizure. As little as one spoonful of dirt in a tank of unfiltered fuel can ruin a fuel injector

in less than eight hours.

Filters – Fuel Water Separator Retrofit Upgrade Options

Fuel Water Separator Retrofit Upgrade Options

Remove debris and water for better protection

High pressures and close tolerances mean today’s fuel injectors, pumps, and components require increased

protection X and Cat Fuel Water Separators provide it. These primary fuel filters:

● Remove over 98% of debris 10 microns and larger- and eliminate virtually all free water and over 87% of

emulsified water.

● Minimize the risk of plunger-to-barrel scuffing and seizure in fuel injectors, reducing failure rates.

● Extend the life of your engine’s unit fuel injectors and secondary, two-micron, high efficiency fuel filter.

Plus, extensive testing by Caterpillar shows that Cat Fuel Water Separators are structurally tough to resist consider

cracking and failure.

Protect fuel system components from damage

Excess water breaks down the protective film strength of fuel, leading to injector failure. By separating water from

fuel, Cat Fuel Water Separators reduce the chance of damage to fuel system components. Specially treated filtration

media block water, then separate more than 87% of emulsified water from diesel fuel – along with debris 10 microns

and larger. Water collects in a bowl on the bottom of the filter, where you can visually monitor the level and drain it

in less than a minute.

Select the filter for your application

Cat Fuel Water Separators are available for all Cat engines up to and including the 3416 engine. Ask for part number

1R-0769 (with axial seals to allow the retrofit (to engines in the field) or 1R-0770 (with radial seals for new machines

and engines). The water collection bowl is part number 173-7126.

Filters – Hydraulic Filtration Upgrade Options

Hydraulic Filtration Upgrade Options

Choosing the Right Cat Hydraulic Filter

The Cat Hydraulic Filter line now includes Standard, Advanced Efficiency and Ultra High Efficiency (UHE) filters,

providing our customers the best selection and the best engineered protection available anywhere.

Selection Guidelines

In order to choose the right filter for your machine, always begin by consulting the maintenance manual for proper

change interval and recommended filter part numbers. It is usually safe to substitute a higher-efficiency filter, but

never substitute a lower-efficiency filter than the one recommended.

If your transmission or hydraulic system has a filter bypass dash indicator and a Standard filter is recommended,

you can use an Advanced Efficiency or UHE. If you do not have a bypass indicator, consult your Cat Dealer before

upgrading.

Upgrade Procedure and Intervals

Higher efficiency filters can clog sooner because they trap smaller particles which standard filters do not. Clogging

can occur even more quickly after the use of lower-efficiency filters, due to a build-up of fine particles over time.

To ensure maximum protection after a filter upgrade, follow these directions:

1. Install UHE filter for 250 hour interval to clean system

2. Install Advanced Efficiency or UHE filter

3. Sample oil every 100 hours or once a week

4. If bypass valve opens before 250 hours, replace filter

5. Continue checking oil every 100 hours until filter lasts 250 hours or change interval is established

6. After interval is established return to the recommended sampling interval (Oil should remain at a cleanliness level

of 18/15 or cleaner.)

The machine hydraulic system should use Cat Hydraulic Oil, DEO, TDTO-TMS™, or MTO. The cleanliness

level must be monitored with S·O·SSM analysis every 500 hours. (Or when upgrading to a higher efficiency filter, the

above procedure should be followed.) When these requirements are met, the hydraulic change interval can be

increased to 4000 hours.

Note: For extended drain intervals, hydraulic system compartments cannot be integral with service brakes, clutches,

final drives or differentials.

Benefits of increased filter efficiency

Higher-efficiency filters, with their finer filtering media, trap more contaminants than lower-efficiency filters.

Lower contaminant levels reduce wear on system components, leading to extended life and improved performance.

Filters – Cab Air Filtration Upgrade Options

Cab Air Filtration Upgrade Options *Not for use in filtering hazardous materials

Odor Reduction Cabin Air Filters

Caterpillar now offers a selection of charcoal impregnated cabin air filters for use in applications, where odors or

airborne irritants are a concern. These filters provide significant odor reduction, but they are not designed to filter

hazardous materials.

Compatibility and Fit

Odor Reduction Cabin Air Filters can be used as direct replacements for standard filters. No modification is

necessary, and pressure drop is similar to standard, so there is no adverse effect on air flow, A/C and heat

performance, or cabin air pressure. Correct substitutions are indicated in the chart below.

Activated-carbon filtering

Odor Reduction Cabin Air Filters use high-performance activated carbon to quickly absorb odor-causing particles

and reduce odors to a comfortable level. A bonded structure holds carbon in place even in high-vibration conditions

and prevents carbon dusting. This design also makes the filters easy to install and safe to dispose.

Improved particle removal

Odor Reduction filters also provide higher particle removal efficiency, both initially and throughout filter life.

Fewer particles of soil, dust, pollen, mold spores and other irritants enter the cab, even after sustained use.

High surface dust loading

By holding more dust on the surface, Odor Reduction Cabin Air Filters provide a number of benefits. They last

longer, are easier to clean, protect the A/C core from performance-robbing build-up, and reduce maintenance costs

for the HVAC unit.

Cleaning and replacement guidelines

Cleaning and re-use is recommended for Odor Reduction filters under the following circumstances:

● airflow restriction is increased

● filter is not damaged

● filter has been used less than 12 months

● odor reduction capabilities are still good

To clean the filter, use compressed air at 70 psi or less with a 1⁄8" diameter nozzle at a minimum distance of 2".

Replace damaged filters, filters used longer than 12 months or filters that no longer reduce odors.
