PICSSUPRA1ENSTU DYIntroduction

Our new Supralon™ ﬁlters represent a signiﬁcantadvancement in equipment protection and are a direct
replacement (same form, ﬁt, and function) for current
Coralon and Ultipor III ﬁlter elements (typically partnumbers preﬁxed with “HC”). Supralon ﬁlter elements
have been designed to deliver the best performancefeatures its predecessors plus more. We have added
static charge resistance properties and increased theﬁlter performance rating to BetaX(C)=2000, the highest
rated performance in industry today.

Having completed extensive laboratory trials to evaluate
the performance of this new advanced ﬁlter, Pallundertook a signiﬁcant number of ﬁeld trials globally,
to test the performance across a number of challenging
applications.
Application
A major automotive component supplier utilises a ring
main to supply ﬂuid to 30 test rig stations for the pumps
and injectors for off highway vehicles.
The ring main currently utilises Pall HC8314FCPZX321 deep
pleat Coralon ﬁlter elements to control the cleanliness toISO 4406 maximum level of 16/14/12 (Fuchs Calibration
ﬂuid to ISO 4113. 2.5 cSt @ 40 deg C).
The customer agreed to trial 3 off new Supralon
HC8314FRP39Z (3 micron rated Beta3(C) ≥ 2000)
replacement ﬁlter elements, to test the performanceand life in this known high particulate ingression
application which also sees assembly debris and grease
contamination.
The ring main was chosen as the challenging application
had previously experienced shorter ﬁlter element service
life before being changed to a deeper pleat, ‘X321’ ﬁlter
element design in 2016.
Field trial
The trial started April 21 under increased production
conditions. The ﬁrst ﬁlter element lasted 4 ½ weeks andnext two, 3 and 3 ½ weeks respectively, the same ﬁlter
element service life as the previously ﬁtted X321 element
life.

Results
Pall engineers returned to site to take online ﬂuid samples
using the Pall Cleanliness Monitor PCM 500 and bottle
samples to verify the ﬂuid cleanliness in the laboratory.
The cleanliness was consistently maintained below therequired speciﬁcation and ranged from highest (taken
just after changing an element) at ISO 15/13/10, to twosamples below ISO <11/<9/<7 per ISO 4406.
A blocked element was also returned to the laboratory
for further analysis. It was noted that the media was fully
utilised with evidence of black / bright metal , silica andgrease, as expected.
In conclusion the cleanliness of the ﬂuid and service lifeof the ﬁlter element was the same or slightly better thanutilising the original Coralon X321 ﬁlter element, achieved
with no adaptation to the existing housing or increased
cost of ﬁltration.
The customer was satisﬁed with the trial and has agreed
all future supply to the system be with the new Pall
Supralon replacement ﬁlters.
As numerous applications can now be covered by one
Supralon part number, the customer is also reviewing hissite to standardize supply.
Although no evidence of ESD (electrostatic discharge)
or varnish was seen in the system on this occasion, thecustomer has peace of mind that the ring main system isfurther protected by the anti-static properties additionallyoffered by the Supralon ﬁlter element.
