L-Pak Construction The L-Pak is specially designed for lubrication applications.
Using the same five layer construction as the C-Pak,
the L-Pak also has a deep pleat construction to maximize element life in steady flow, low pulsation systems
Target Cleanliness Using the Vickers Target Cleanliness Worksheet (#578),
it is easy to determine the target ISO Cleanliness Level for a system.
This target is based on the application’s components and system dynamics.
Placement and Media Use the chart below to help select the appropriate filter placement and grade of media to achieve the target cleanliness level.
For more detail, consult “The Systemic Approach to Contamination Control”, your Eaton representative,
or the ANSI Systems Standards for Stationary Industrial Machinery.
C-Pak Construction C-Pak media uses five layer construction.
layers of epoxy coated carbon steel wire to retain the inner media pak layers.
? Check that the filters are positioned properly to see maximum fluid flow. ? Consider using a finer Pak grade. ? Add a filter to the system.
Note All systems need a sealed reservoir with vent port filtration.
Before servicing the element, the bleed plug in filter housing must be loosened to relieve pressure.
This will minimize fluid overflow.
Filter Placements The chart below helps engineers select the grade of Vickers media and the filter placement(s) that will achieve the required target cleanliness.
It assumes the system will experience ‘‘average’’ ingression and that maintenance of the system will be consistent with current technology.
C-Pak incorporates epoxy coated carbon steel as the two outer face layers to retain the inner media pak layers.
R-Pak Construction The R-Pak spin-on filter elements are designed for low clean pressure drop and high efficiency.
R-Pak incorporates a five layer media construction with outer
All Vickers filter elements are constructed with five layers, making them durable and highly efficient.
1. High strength support
2. Non woven synthetic diffuser layer
3. Vickers glass micro fiber media with special resin binder
4. Non woven synthetic diffuser (drainage) layer
If in operation the system is running dirtier than expected, corrective actions should be initiated. S
uggested corrective actions are: ? Check the indicator to see if the filters are on by-pass.
? Check the sources of ingression and correct problems.
Housing The selected housing should be rated within the required flow and pressures of the application.
Important: If the system fluid’s specific gravity (SG) is greater than 0.9 (for example, water glycol),
the housing pressure drop (?P) should be corrected for the actual application.
Specific Gravity Corrections for Pressure Drop
The filter housing flow curves in this catalog can be adjusted using the following equation:
Adjusted ?PHousing = ?PCurve x Actual SG 0.9 Bypass Valve Bypass valve selection is based upon system requirements.
According to ANSI Standard 12.2.6, filter assemblies whose elements cannot withstand full system differentia
l pressure without damage should be equipped with bypass valves. Generally,
a higher bypass pressure setting will allow for longer element life.
Some systems require filtration with no bypass, such as servo applications. Vickers H-Pak media is recommended for non-bypass systems.
5. High strength support
H-Pak Construction For systems where a bypass valve is undesirable,
such as servo systems, the H-Pak media provides high collapse rated housing pressures.
H-Pak media construction utilizes 304 stainless steel inner and outer mesh support
along with heavier core tubes and media support to protect the system.
