elements only rated to βx[C]= 75~200 can allow ISO
fluid cleanliness codes to increase by two to threecodes per size. This will lengthen the time interval

Don’t assume that a filter element will retain theparticles it has captured. DFE testing reveals
that filter elements designed and validated
ONLY to antiquated industry standard ISO
16889 (ISO4572) multipass testing are prone todischarge previously captured contamination.
When subjected to real world dynamic conditions
highly concentrated clouds of contaminate arereleased by some filter elements This can inhibit
reliability, cause severe damage, and accelerate
failure of sensitive components. With DFE
rated Hy-Pro elements you get clean fluid undernormal AND severe operating conditions.

Cleaner Fluid, Longer Component LifeLab and field tests prove time and again that Hy-Pro filters deliver lower
ISO cleanliness codes, and do it with greater consistency. Improving
and stabilizing fluid cleanliness can increase hydraulic component andbearing life exponentially. Cleaner fluid also yields reduced downtime,
more reliable equipment performance, fewer maintenance hours, longer
fluid life and reduces costly component replacement or repair expenses.

GLASS UPGRADE

Hy-Pro G8 Dualglass Upgrade from Cellulose Media
Glass media has superior fluid compatibility versus cellulose with hydraulic fluids, synthetics, solvents, and highwater based fluids. Glass media also has a significant filtration efficiency advantage over cellulose, and is classified
as “absolute” where cellulose media
β10μ(c)=2
efficiency is classified as “nominal”.
50000
β10μ =2 _____

Elements of different media with the same
“micron rating” can have substantially different
filtration efficiency. Figure 1 provides a visual
representation of the difference between
absolute and nominal filter efficiency.

Glass media has much better dirt holding
capacity than cellulose. When upgrading toan absolute efficiency glass media element
the system cleanliness must be stabilized.
During this clean-up period the glass element
halts the runaway contamination as the ISO
cleanliness codes are brought into the target
cleanliness range. As the glass element
removes years of accumulated fine particles
the element life might be temporarily short.
Once the system is clean the glass element
can last up to 4~5 times longer than thecellulose element that was upgraded asshown in figure 2.

Understanding ISO Codes - The ISO cleanliness code (per ISO4406-1999) is used to quantify particulatecontamination levels per milliliter of fluid at 3 sizes 4μ(c), 6μ(c) and 14μ(c). The ISO code is expressed in 3 numbers(example: 19/17/14). Each number represents a contaminant level code for the correlating particle size. The code
includes all particles of the specified size and larger. It is important to note that each time a code increases the quantity
range of particles is doubling and inversely as a code decreases by one the contaminant level is cut in half.

Succeed with a Total Systems Cleanliness Approach

Developing a Total System Cleanliness approach to control contamination and care for fluids from arrival to disposal
will ultimately result in more reliable plant operation and save money. Several steps to achieve Total Systems
Cleanliness include: evaluate and survey all hydraulic and lubrication systems, establish an oil analysis programand schedule, insist on specific fluid cleanliness levels for all new fluids, establish a baseline and target fluid
cleanliness for each system, filter all new fluids upon arrival and during transfer, seal all reservoirs and bulk tanks,
install high quality particulate and desiccant breathers, enhance air and liquid filtration on existing systems whereversuitable, use portable or permanent off-line filtration to enhance existing filtration, improve bulk oil storage andhandling during transfer, remove water and make a commitment to fluid cleanliness.
The visible cost of proper contamination control and total systems cleanliness isless than 3% of the total cost of contamination when not kept under control. Keepyour head above the surface and avoid the resource draining costs associated withfluid contamination issues including:••••Downtime and lost production
Component repair/replacement
Reduced useful fluid life
Wasted materials and supplies ($)

Root cause analysis meetings

Wasted time and energy ($)

When setting target ISO fluid cleanliness codes for hydraulic and lubrication systems it is important to keep in mind theobjectives to be achieved. Maximizing equipment reliability and safety, minimizing repair and replacement costs,
extending useful fluid life, satisfying warranty requirements, and minimizing production down-time are attainable goals.
Once a target ISO cleanliness code is set following a progression of steps to achieve that target, monitor it, and maintain it
will yield justifiable rewards for your efforts. Make an impact on reliability by controlling contamination.
Set the Target.
The first step in identifying
a target ISO code for asystem is to identify the mostsensitive component on an
individual system, or themost sensitive component
supplied by a central
reservoir. If a central reservoir
supplies several systems
the overall cleanliness must
be maintained, or the mostsensitive component must
be protected by filtrationthat cleans the fluid to thetarget before reaching thatcomponent.
Other Considerations.
Table 1 recommends
conservative target ISO
cleanliness codes basedon several component
manufacturers guidelines andextensive field studies forstandard industrial operating
conditions in systems using
petroleum based fluids. If a
non-petroleum based fluid isused (i.e. water glycol) thetarget ISO code should be
set one value lower for eachsize (4μ(c)/6μ(c)/14μ(c)). If a
combination of the following
conditions exists in thesystem the target ISO codeshould also be set one value
lower:• Component is critical tosafety or overall system
reliability.
• Frequent cold start.
• Excessive shock orvibration.
• Other severe operation
conditions.
