Banner featuring various Quality Protection filter element products

‘Will-Fit’ Doesn’t Cut It

Keeping a hydraulic system free of contamination is critical for system efficiency and longevity, and high quality filtration elements are the key to contamination control. Unfortunately, it’s not uncommon for customers to seek out low-cost, off-brand imitations of Schroeder Industries filter elements in order to cut down on expense.

Not all filter elements are created equally, and just because a given element fits in a Schroeder filter housing, it doesn’t necessarily provide adequate filtration. Cut-rate imitations may claim that “All filtration elements are guaranteed to meet or surpass all specifications of the original equipment manufacturer” but that’s not always the case. Take a look at the numbers below and see for yourself:

Cheaper knockoff filter elements trade functionality for lower cost, exposing the hydraulic system to increased risk of contamination, machine downtime, and system failure. Furthermore, the blame for these failures may be wrongly placed on the housing manufacturer, not the cut-rate filter element.

How can we ensure that proper, high-quality filtration elements are being used?

Quality Protection: Guaranteeing High Quality Filter Elements, Every Time

Quality Protection is Schroeder’s answer to the problem of mismatched, inadequate elements. The patented, premium Quality Protection elements are engineered specifically for superior performance when paired with Schroeder filter housings.

Exceptional Fluid Contamination Analysis with Total Fluid Condition

Image of the total fluid condition unit, for identifying fluid contamination

Mitigating fluid contamination is a chief concern for hydraulic systems. Solid, liquid, and other forms of fluid contamination account for up to 90% of all hydraulic system failures. Water, ingested particulate contamination, and metal particles from internal component wear are just a few types of contamination. Contamination is influenced by ambient conditions and other variables, and can have serious impacts on hydraulic equipment performance.

Contamination cannot be completely stopped, but proper fluid filtration can prolong the lifespan of your hydraulic components—and a successful treatment strategy begins with accurate diagnostics.

Portable Fluid Condition Monitoring

To make fluid assessments more convenient, Schroeder Industries developed several portable fluid condition monitoring systems. These compact units are designed to deliver real-time insights into the health of a variety of hydraulic fluid types. On-site analysis with a portable condition monitoring unit saves time and money compared to shipping samples to oil testing labs, or using complicated analysis kits. Their portability makes them usable in the field, in remote locations, along a manufacturing process production line—anywhere a hydraulic system can be found.

Image of the total fluid condition unit, for identifying fluid contamination

Introducing Total Fluid Condition (TFC)

The new TFC unit represents the latest in fluid condition monitoring technology. This revolutionary portable service unit is designed to measure and differentiate particulate contamination, as well as relative water content and temperature.

Improving Contamination Data Accuracy

Correctly identifying the type and source of hydraulic fluid contamination is critical for developing a treatment strategy. The TFC unit improves upon the accuracy of fluid contamination data in synthetic and mineral oil based hydraulic fluids, offering users a more complete analysis of their fluid health than was previously possible. This improved precision stems from the new direct digital imaging sensors incorporated into the TFC units.

Image showing fluid contamination identified as particles, specifically shaped particles, and air bubbles

Other portable fluid contamination monitoring units have utilized light-based sensors, which struggle to differentiate between contamination types, but direct digital imaging sensors can distinguish air bubbles and water molecules from solid particles. This results in a more accurate ISO count, and better understanding of the fluid’s health.

The TFC can also sort particles into fatigue, cutting, sliding wear, and fiber categories to estimate cause of contamination. The direct imaging particle counting software coded into the unit uses size and shape-recognition technology, based on advanced algorithms, as a dirt classifier to distinguish contaminates.

TFC Applications

Like Schroeder’s other portable fluid diagnostics systems, TFC is a powerful, versatile tool for any fluid cleanliness testing scenario:

  • Perfect for in-plant/industrial applications, during the assembly process or at the end of the production line.
  • The compact design and onboard battery also make the TFC ideal for mobile applications, such as testing for service trucks or in remote locations.

Other Benefits of Fluid Condition Monitoring

The oil waste reduction aided by the TFC unit’s fluid diagnostic capabilities doesn’t just help protect your equipment. It also reduces costs and environmental impacts related to oil waste.

All hydraulic fluid must be changed eventually, but routinely testing fluid cleanliness and addressing contamination prolongs its lifespan. This results in less frequent oil disposal, saving on the expense of new oil.

Additionally, the reduction in hydraulic oil waste and consumption helps lower an operation’s carbon footprint and environmental impact. The TFC unit is part of Schroeder Industries’ 2030 Initiative supporting carbon neutrality goals across various industries, thanks to the benefits it imparts by helping extend the life of oil and reduce waste.

Electric Hydraulics: Revolutionizing the Mobile Hydraulics Industry

The Future of Hydraulics is Electrifying

In recent years, the mobile hydraulics industry has been revolutionized by the development and proliferation of electric hydraulic systems. Among other inherent benefits, electric hydraulic systems could also be dramatically more energy efficient compared to traditional hydraulic systems.

How is this possible? Unlike traditional hydraulic systems, electric hydraulic motor-pump units only operate when flow and pressure are required to perform the working task at hand.

When there is no flow or pressure required, the electric hydraulic motor-pump unit switches to zero energy-mode, saving the consumption of energy and increasing the system’s efficiency. This is what we call energy efficiency.

Energy Efficiency through Electric Hydraulics

Energy efficiency logo symbol

Energy efficiency, put simply, is when less energy is needed for a system to get the job done. This can be achieved by lowering the amount of energy consumed to accomplish an equivalent output (e.g. halt of use when not in operation).

Think about some of the newer car models in the market today.

Some higher-end models shut down every time the car stops at a stop light. Since the car is in idle at that stop light, why would the car continue to place tension and wear the performing components when they’re not performing their sole duty: driving?

This way of thinking is slowly creeping into hydraulics too. Experts are now looking at ways to incorporate these (and other) types of electric energy to power hydraulic machines. This is called electric hydraulics.

Electric Hydraulic Advantages

Eleectric Drive Media with check mark

Electric hydraulic systems have some major advantages over their traditional hydraulic counterparts. The key advantages of electro-hydraulic motor pump units are:

  • Up to 70% more efficient than standard hydraulic counterparts
  • CO2 reduction = less fluid being used in the system
  • Component lifespan increased, especially with bearings and seals
  • Ability to control direction & amount of hydraulic flow by controlling direction/speed of the electric motor.
    • Injection molding machine systems eliminate the need for directional and proportional valves in the motion axis.
    • Fewer, less complicated components also simplifies troubleshooting.
  • Quieter run times, reducing noise decibel readings
  • Save space and reduce weight with lighter, more compact electric systems
  • Integrated electrohydraulic packages are now available. These packages include an electric motor, controller, and hydraulic pump combined into one compact unit to lower total cost of ownership.

With the rising trend of electric drive vehicles and utilizing efficient energy throughputs, there is now a need to reduce power consumption and extend the battery life through increased hydraulic efficiency. How do we capitalize on saving energy and becoming more efficient in electric hydraulic systems?

The answer: minimize the pressure drop

Electric Drive Savings Through Pressure Drop Reduction

All energy has a price, and wasting it means wasting meaningful dollars. It is desirable to have as much energy that is inputted into a system available to do useful work. In hydraulic systems, we tend to look at differential pressure across the entire system. Differential Pressure describes the loss of energy available in a hydraulic system—however, the energy is not lost, but converted into thermal energy, which is unavailable to perform useful work.

For example, a small pressure drop effects high horsepower systems, as the pump/motor group must make up for that loss of energy and operate much harder, costing more money and shortening component life. Take a look at the figure below to see an example of how much money can be saved by lowering the pressure drop by a few psi:

Graph depicting electric drive savings through pressure drop reduction
*Assuming electric driven operation at 65% efficiency. $ Savings based on energy cost of $0.15/kw-hr & ~6000 hours per year on an electric driven operation.

So how do we lower the overall pressure drop in an electric hydraulic system? That is where Schroeder’s Electric Drive media can help.

Schroeder’s Electric Drive Media

Schroeder Industries Electric Drive Media for electric hydraulic systems

The use of Schroeder’s GREEN, Electric Drive (E-Drive) Media filtration technology guarantees safe and reliable equipment operation, all-while conserving the use of energy.

Part of Schroeder’s Energy Saver initiative, filter elements made using the all-new E-Drive Media are characterized by a low pressure drop, making them suitable for low energy requirements compared to conventional hydraulic elements under the same ambient conditions.

In certain applications, the E-Drive Media can lower the pressure drop to a point where consumers may be able to size down their horsepower requirements on their current motor and save even more overall!

E-Drive filter elements are made using an all-new specialty formulated, high efficiency, low differential pressure media and are the perfect choice for use in electric hydraulic drive motor-pump units. Use them for conserving energy bills and wherever high viscosity fluids are employed – especially at low temperatures that produce a cold start behavior.

Let’s see how our 10-micron Electric Drive media element compares to the typical synthetic microglass media available on the market today.

Technical Specs (evaluated in K-sized element):

Protect Your Hydraulic System with Remarkable Contamination Control

Graphic with link to the hydraulic lube filtration catalog

Fluid Contamination Control: What You Need to Know

Typographical image reading: "In hydraulic systems, 70-90% of wear & failure is contamination related."

Over 70% of all system failures are caused by contaminants in the fluid. Even when no immediate failures are apparent, high contamination levels can be present and sharply decrease hydraulic controls in the blink of an eye.

Contamination is defined as any substance foreign to the manufacturing equipment and damaging to its performance. If not controlled, contaminated hydraulic fluid can impact hydraulic system efficiency, reduce the lifespan of machine components, or even cause a catastrophic failure of hydraulic equipment, among other issues. Proper preventative measures, namely filtration, are critical.

There are four primary types of fluid contamination, each of which contribute to machine and component wear in their own ways. Each type of contamination can have a cascading effect which contributes to the other types.

Graphic representing the four types of fluid contamination: solid, liquid, gaseous, and gel-like
Image of solid-type fluid contamination

Solid contamination can lead to worn sealing surfaces and surfaces that cause leaking points for external air and moisture ingression and can also lead to friction-induced localized thermal degradation.

Solid contamination, generally referred to as particulate contamination, comes in all sizes and shapes and is normally abrasive to major components in the hydraulic system.

With this abrasive quality, a high contaminant level accelerates component wear and decreases the hydraulic supply and service life.

Worn components, in turn, contribute to:

  • Inefficient hydraulic machine operation
  • Seizure of hydraulic parts (such as hydraulic pumps, cylinders, and hydraulic motors
  • Higher fluid temperatures
  • Leakage
  • Loss of control
Image of liquid-type fluid contamination

Liquid contamination (i.e. water) can accelerate the fluid aging process and generation of varnish. Water contaminated hydraulic fluid can also cause corrosive pitting of metallic components and therefore generate solid metallic particle contamination.

Image of gaseous-type fluid contamination

Gaseous contamination (i.e. air) can cause cavitation and dieseling effects which may lead to particle contamination and local thermal degradation.

Image of gel-like fluid contamination

Gel-like contamination—such as varnish created by oil degradation—can be a root cause of accelerated aging, increased particle generation via changing and inadequate lubrication properties, as well as the formation of water from chemical reactions.

Contamination can also act as a catalyst to accelerate oxidation of the fluid and spur the chemical breakdown of its constituents.

Trusting the Experts on Process Filtration Results in Reliability

Graphic with link to download the process filtration catalog

What is Process Filtration?

Process filtration is a major focal point of what we do at Schroeder Industries.

The filtration process is commonly used to remove contamination and solid particles from gas-solid or liquid-solid process streams.

Additionally, there are filtration solutions to improve one’s operating water quality. This includes:

  • Process water
  • Waste water
  • River water
  • Cooling towers
  • Backwash
  • Industrial gases
  • Low-viscosity fluids
  • And all other types of oil, fuel, water, and compressed gases

We’ve even coined the phrase “if it flows, it’s probably Schroeder”.

Trust the Experts of Process Filtration

Proper filtration in treatment processes such as process water, wastewater discharge, or reuse is critical.

Moving liquids or gases from somewhere like a refinery, food/beverage, steel, automotive, pulp and paper or oil produced water application requires pre-filtration due to high amounts of suspended solids in these typical applications.

In fact, there are usually several filtration and treatment steps in these applications to ensure that the treated water meets the required discharge or reuse standard.

In addition, filtration in treatment schemes ensures reduced operating cost on downstream polishing treatment systems.

Schroeder Industries Focuses on Your Process, Delivery Reliability and Improvements

Schroeder Industries will optimize your filtration solution based on the specific characteristics of your system, including the water source, specific application, and downstream equipment.

Poor filtration can cause a degradation of your final product or failure of downstream equipment. This can cost hundreds of thousands, or even millions of dollars in downtime or wasted product.

Schroeder Industries is here to partner with you to ensure reduced maintenance and high quality filtration designed specifically for your application.

The most important aspects of the application of filtration process include:

  • Performance
  • Efficiency
  • System parameters
  • Stable emulsions
  • Water intake
  • Economic impact

For instance, a very important step in a membrane treatment plant in the United States is the pretreatment of fluid to remove large particulate and biologicals.

If unmanaged, poor prefiltration can result in:

  • Increased maintenance costs
  • Increased energy consumption
  • Damaged components (like a pump or heat exchanger)
  • Reduced service times

Schroeder’s Powerful Technology for Oil Conditioning

Graphic with to link to the fluid filtration systems & diagnostic catalog

What is a Fluid Filtration System?

A fluid filtration system is exactly what it sounds like. These systems are designed to ensure the quality of your fluid is excellent.

With a typical hydraulic application, the hydraulic filter is normally plumbed in-line with the system (or buried in-line with a hydraulic tank) and serves as an oil conditioning unit when the system is in operation.

Graphic detailing the differences between a typical hydraulic filter and a fluid filtration system

A fluid filtration system, or oil conditioning unit, is a stand-alone unit that operates offline and away from the hydraulic application. Often times in the form of a hydraulic filter cart, it is not to replace any piece of equipment, but to enhance the maintenance team.

Equipped with a pump-motor group of its own, these do not require the power of a hydraulic machine. They are their own system.

Oil conditioning units are typically used for the conditioning of stored fluid, fluid dispensing applications and transferring processes. It is basically summed up that everywhere the fluid is not flowing through a system, it should be accompanied by a hydraulic filter cart.

What is meant by “Oil Conditioning”?

With the turn to tighter tolerances in today’s hydraulic critical assets systems, line conditioning equipment is critical.

Typographic image which reads: In hydraulic systems, 70-90% of wear and failure is contamination related.

What do we mean when we say “Oil Conditioning”? 

Oil Conditioning is using fluid conditioning products, such as offline oil filtration and dehydration systems, to remove contaminates and increase the moisture removal rate in your hydraulic fluid.  Removal of the contaminates and the total moisture allows the system to operate to its fullest potential. Contamination is a leading cause of hydraulic repairs and replacements, and accounts for 70 to 90% of wear and failure.

Whether your machine is new or many years old, the cleaner the oil, the better the operating condition.

When contaminants enter a hydraulic system, the manufacturer’s advertised performance of that machine is not achieved.

This adds an increased strain on components such as turbine oil filters, other line conditioning equipment, and more.

Today’s oil conditioning units have seen a shift from “Reactionary” (fix it when it breaks) to “Preventative” (fix it before it breaks), and even “Predictive” (schedule downtime to perform maintenance).

What are Diagnostics Tools?

Similar to a diagnostic OBD II scanner you have for your car, diagnostic tools are the equipment that can recognize and support a “Preventative” maintenance plan.

Bring that into the world of hydraulics and you get equipment similar to the OBD scanner mentioned above.

Only this time, these diagnostics read and report in the form of mineral oil cleanliness.

Watch on YouTube “Diagnostics (IoT)” Playlist.

What do Diagnostics Tools have to do with Oil Conditioning Units?

When you pair the elite technology found in today’s oil conditioning units with the new-age of the Internet of Things (IoT) technology in most diagnostic tools on the market today, you really step into the future in a real effort of streamlining tedious oil sampling/reporting tasks in a complete system.

The two technologies together are what we like to call proactive “Contamination Control” – taking ownership and managing the fluids you pump into your hydraulic systems day-in and day-out.

“Contamination Control” pertains to the ISO clean analysis and optimization of processes with regard to the cleanliness of components, systems and the purity of the fluids used.

“Contamination Control” is also an important part of operating and maintaining hydraulic systems, like a hydraulic filter cart.

How can Schroeder Industries help?

It starts with the identification and measurement of the different forms of contamination.

Our line of condition monitoring products include both in-line and offline sensors to measure contamination and/or total moisture levels of the hydraulic system.

If the contamination levels are at a certain degree, our end users have seen dramatically frequent equipment failure.

If monitoring is the first step, fluid conditioning products would be the second.

Our line of offline, mobile fluid handling carts are perfect for removing contaminants and increasing overall moisture removal rate from various types of hydraulic fluids.

Oil conditioning units include both mobile fluid handling carts with or without contamination monitoring units, stationary fluid conditioning products from 1.3 gpm flow rates to customizable kidney loop systems up to 140 gpm.

Each of our hydraulic filtration systems are equipped with high efficiency elements to remove solid particulates and/or free water quickly and efficiently.

Our dewatering units, both hydraulic vacuum oil dehydration and mass transfer systems, can remove both free and dissolved water from hydraulic fluids for any reservoir size at various flow rates.

Watch on YouTube “Filter Systems” Playlist.

By implementing fluid condition monitoring equipment, in conjunction with the appropriate filtration equipment, a major portion of particulate contamination introduced during manufacturing and assembly can be effectively and efficiently removed.

The result will be improved fluid condition, extended life expectancy of fluid and equipment resulting in significant cost savings, and peace of mind that your systems are functioning appropriately and efficiently.

Overcoming “Phantom” Particle Counting

Overcoming “Phantom” Particle Counting

Digital Imaging Picture shows operating software of Schroeder Pro: Total Fluid Health

Imagine this…

  • You have been filtering 30 gallons of your operating fluid in bypass with staged 5- and 1-micron filter elements at a processing rate of five gallons per minute (gpm) (300 gallons per hour (gph)).
  • You have been using a Light Blockage Method (LBM)-based portable particle counter to verify the fluid cleanliness.
    • The starting cleanliness per ISO 4406 2017 was 25/22/15 ISO cleanliness code.
  • After eight (8) hours, the cleanliness has only dropped to 22/20/13 ISO cleanliness code.
    • A difference of about 3 points.
  • You’ve checked that the filter element is not clogged and not in bypass.
    • You even went through the trouble of making sure there was an element actually in the filter!

How could this be possible?

It couldn’t be, right?

What you’re likely experiencing is a classic case of “phantom” particle counting.


Demystifying the “Phantoms” in your Fluid

“Phantom” particle counting is a documented problem faced when using LBM portable counters to verify the oil cleanliness class of petroleum-based fluids containing certain insoluble additives.

Silicone-based antifoam agents are common interferents of LBM particle counters.

Fluids used in mobile fluid power systems are typically formulated to contain high antifoam concentrations.

Research has suggested that through differential surface tension, the silicone antifoam additive agents adhere to the inner wall of microscopic, entrained air bubbles, resulting in micelle-like encapsulations of the additive agents that then take on the apparent shape characteristics of a water droplet [1].

The measurement of particle size for micelle-like antifoam agent encapsulations typically range in 4-10µm size range [2].

Once the encapsulations rise to the fluid surface, the agents quickly pierce the air bubble and return back into the fluid.

In a related study of the effects of a variety of non-solid contaminants and additives on LBM particle counting accuracy, it was found that a base stock mixture containing 0.02% (by weight) of a silicone antifoam agent increased the LBM laser particle count by a minimum factor of three [1].

The erroneous particle accounts were particularly evident in the 4µm and 6µm channels of the ISO 4406 2017 cleanliness standard [2, 3] (see also NAS cleanliness standard or SAE AS4059).


Limitations of the Light Blockage Method (LBM)

LBM or Light Blockage Method fluid analyzers are useful in many applications.

The principle of the light blockage method is fundamentally simple: fluid flows through a measurement cell containing a light source on one side of the measurement cell, and a receiver (photodetector) on the opposing side of the measurement cell.

The light source becomes partially blocked as the number of particles pass through the measurement cell, creating a light radiation differential—a shadow—corresponding to the circular cross-sectional size of the passing particles.

The operating principle measures particles based on the space between the shadow and the receiving end of the light source.

Because of this fundamental operating principle, LBM portable counters suffer from a key drawback: the lack of and the inability to discern solid contaminates (like metallic composition) from other contaminates like water, air bubbles, “phantom” particles, and so on.

So, how can the “phantom” particles be overcome using oil particle counter sensor technology?

There is an alternative solution to this question: oil particle counting using the Direct Imaging Method.


Direct Imaging Method

Direct Imaging particle counting software uses size and shape-recognition technology, based on advanced algorithms, as a dirt classifier to distinguish contaminates.

For example, a Direct Imaging portable information counter can distinguish contaminates into fatigue, cutting and sliding wear with a metallic wear debris sensor and fiber and air bubble categories based on shape characteristics.

It can also recognize water droplets.

The distinction of contaminates allows for a more accurate particle counting by negating non-solid contaminates like entrained air bubbles and water droplets.

Therefore, Direct Imaging particle counting technology can negate the micelle-like antifoaming additive encapsulations as water droplets— “phantom” particles—allowing users to understand the condition of their fluid samples with confidence.

Case Studies 1 and 2 demonstrate how the Schroeder Pro: Total Fluid Health (TFH)–one example of a fluid condition monitoring solution with Direct Imaging particle counting technology–can be used in practical applications to overcome “phantom” particle counting.


Case Study 1

An OEM of large off-highway equipment was experiencing continuous oil particle counter inaccuracies at a verification stage of assembly:

  • The rejections due to fluid condition were mounting, causing delayed shipments and significant related costs.
  • The average holding time delay due to rejection was seven days and incurred a holding cost of $1,500, per day, per unit.
  • At the consultation phase of the case study, eight units had been delayed.

The diagnosis was in…

The existing light-blockage-type particle counters were providing inconsistently high and erroneous particle counts.

The ISO 4406 2017 ISO cleanliness code would frequently measure a 23/22/19 size range, despite a strong fluid maintenance and conditioning regime.

Third-party fluid analyzer reports and fluid datasheets suggested that the fluid (synthetic hydraulic fluid) contained a high concentration of a siloxane (silicone derivative) antifoaming additive known to cause “phantom” particle measurements in LBM automatic particle counters.

Schroeder Industries provided an extensive on-site demonstration that proved the advanced Direct Imaging Method technology of the Schroeder Pro: Total Fluid Health (TFH) hydraulic fluid particle counter solution, which measured an average ISO 4406 2017 fluid cleanliness of 15/14/10, allowed the customer to successfully process the fluid of and pass six units during the first day of demonstration.

The two remaining backlogged units passed early on the second day of demonstration.

The realizable savings—evidenced by the demonstration—equated to:

  • Approximately 35% in cost savings and
  • 81% reduction in holding time.


Case Study 2

Similar to Case Study 1, an OEM of mobile equipment was measuring unusually high particle counts with their LBM computer particle analyzer after switching to a new hydraulic fluid type with a higher concentration of an antifoaming additive.

Coincidentally, the fluid type was nearly equivalent to that used by the off-highway equipment OEM.

According to the customer, the average oil particle counter of four fluid sample trays of fluid collected from the customer’s well-conditioned bulk fluid storage measured 25/23/20 iso cleanliness code, as shown in table 1.


Sample ≥4µm ≥6µm ≥14µm
I 25 23 19
II 25 23 19
III 25 23 21
IV 25 23 19
Average 25 23 20

Table 1 Sample cleanliness results of fluid containing a high concentration of antifoaming additives according to ISO 4406 2017


After consulting the customer of the “phantom” oil particle counting issue, Schroeder Industries offered to process fluid samples using a third-party LBM portable counter and the Schroeder Pro: Total Fluid Health (TFH) hydraulic fluid particle counter solution to determine if there was evidence of the phenomenon.

Because of the tell-tale symptoms of particle counting inaccuracies due to “phantom” particle size analysis, the results of the tests shown in table 2 are not surprising; the test results are consistent with typical cleanliness discrepancies produced by “phantom” particles.


Sample Processed w/ Third-Party LBM Particle Counter Processed w/ TFH
I – Bulk Fluid Storage Tank 24/23/18 17/16/15
II – Machine Reservoir 23/21/16 18/17/16

Keep on Counting…with Direct Digital Technology

It’s no secret that understanding fluid cleanliness is imperative for strategically maintaining fluid-powered and lubricated machines.

Automatic particle counters using the Light Blockage Method (LBM) are generally considered reliable solutions for fluid storage monitoring.

However, LBM particle counters can yield inaccurate measurements while processing fluids that are contaminated by water, entrained air, or high levels of certain additives.

Silicone-based antifoaming agents are common, well-documented additive interferents that become encapsulated within entrained air bubbles that lead to a phenomenon referred to as “phantom” particles.

“Phantom” particles are indiscernible by LBM particle counters due to their fundamental principle of operation.

Research suggests that “phantom” particles can lead to LBM particle counter measurements to be greater than three classes higher than the true cleanliness per ISO 4406 2017.

While they can be filtered out—one possible reason for the slight cleanliness improvement in the hypothetical scenario of the introduction–the additives that can lead to “phantom” particles serve important, specific functions and should not be removed or sacrificed.

An alternative solution to LBM automatic particle counting is the Direct Imaging Method.

The Direct Imaging Method of particle counting uses size and shape-recognition technology in tandem with advanced data-driven algorithms to distinguish solid contaminates into metallic wear debris sensor and fiber categories, and from non-solid contaminants like water droplets and air bubbles.

Because of the apparent water droplet-like shape characteristics of the antifoam encapsulations, Direct Imaging solutions such as the Schroeder Pro: Total Fluid Health (TFH) can indirectly negate the “phantom” particle counts and provide more accurate fluid cleanliness measurements.
