A compact, cost
effective pressure
filter solution
Designed with the
i
protect
®
patented
filtration technology
The Parker EPF
i
protect
®
(Ecological
High Pressure Filter) is designed
to provide high quality filtration
of hydraulic systems, providing
new possibilities to reduce the cost
of ownership by improving their
productivity and profitability.
A radical, innovative approach
was applied with the design of the
EPF
i
protect
®
, suitable for a flow
capacity up to 700 l/min at 450
bar working pressure.
A new patented design of the filter
element allows integration of the
bypass valve and element core as
re-usable parts in the filter bowl.
This makes the product fool proof
as there is no risk of forgetting to
re-install re-usable parts.
With less space being available for
filters, Parker has taken on board
the requirement to provide more
compact solutions. A unique feature
is the filter element remains inside the
filter bowl when changing the filter
element. This can save over 500mm
of space envelope in comparison with
traditional high pressure filters.
Product Features:
The patented element design guarantees the quality of ltration,
which directly impacts the oil cleanliness level as the usage of pirate
type after market lters with unknown quality of lter media is excluded.
This in-build safety has a direct, positive impact on the productivity
and protability of equipment.

Bypass settings are available up
to 7 bar or completely blocked in
conjunction with patented, high
strength lter elements (available
October 2010). e principle is
based on dierential pressure
measurement across the lter
element. During bypass only a
part of the mainow is owing
through the bypass valve.

performance and profit
The new
i
protect®
generation of lter
elements provide high
ltration performance
combined with patented
technology. The bespoke
design prevents the use
of pirate type alternatives.
Less space
needed to
accommodate
the filter
Morecompact
solutions are
possible as the
lter element remains
in the lter bowl during
change of lter element.
Comparedtotraditional
solutions it does not only save
space, it also reduces the required
manual handling during the lter
change process.
Saving cost and
our environment
What does it take
to introduce a new
ground-breaking design
which saves the
environment?Parker’s
EPF
i
protect® applies
a re-usable element core
and bypass, both integral
parts of the lter bowl. This solution
avoids the handling of re-usable
parts during element change and
reducesover50%disposalweight.
Smart valve
technology
Parker
hydraulic
control valve
technology is
applied for the
reusable
bypass valve.
This leakage-
free valve has
a patented interface with the lter
element, which ensures that genuine
parts are always applied. With
bypass settings up to 7 bar ltration
during cold start conditions,
more compact solutions, can be
realised.Thevalvealsooptimizes
theowpath,reducingthe
pressure lost across the lter.
Easier to integrate
Parkerhassetthe
trend to integrate
ltration into
manifolds.
WithParker’sEPF
i
protect® we have
taken the design
one step further.
Onlyonecavityis
needed to accomodate the lter
instead of two, this is because the
re-usable bypass valve is integrated
into the lter bowl, reducing
space and cost.
Customized
solutions
Parker’smotion&
control technologies
provide new
opportunities for
our customers.
Customized
manifolds or duplex
lters, as in this example offer
complete automatic change-over.
TheEPF
i
protect® contributes to
realizingnewsolutions,improving
your productivity and protability.
A protective ‘gene’
The performance and protability
of systems directly depends upon
the lter media.
ItgoeswithoutsayingthatParker’s
patented products aim to avoid the
use of unknown lter performance,
jeopardizingsafetyand
performance.OurMicroglassIII
media is continuously upgraded
andactsasaprotective‘gene’
in the system.
When going
into reverse
Parker’sEPF
can be equipped
with an optional
reverseow.This
valve assembly is
integrated in the
element end cap and isolates
the lter medium during reverse
owconditions.
A new patented design of the lter
element allows integration of the
bypass valve and element core as
re-usable parts in the lter bowl.
This results in cost reduction when
integrating the high pressure lter in
manifold type solutions. But it also
reduces the waste when changing
thelterelementbyover50%as
the element core is an integral part
of the lter bowl.
ThedesignoftheEPF
i
protect®,
is unique, there is no need to
re-install any re-usable parts as
with some other lters in the market.
This makes the product fool proof
as there is no risk of forgetting to
re-install re-usable parts.
