The most energy efficient
compressed air filters in the world
Old filtration technology
NEW filtration technology
Ordinary compressed air filters have always consumed
too much energy, as they are by design, a restriction to air
flow. During their working life, this restriction increases
dramatically, and typically over one year, can consume
more energy than the cost of a replacement element.
Today, many products are offered for the filtration and purification
of contaminated compressed air, however, these are often
selected only upon their initial purchase cost, with little or no
regard for the air quality they provide or the cost of operation
throughout their life.
Operational costs come from differential pressure or
pressure losses across the filter. This pressure loss is a
combination of fixed pressure loss from the housing and
variable losses from the filter element.
Most manufacturers recommend
replacement of the filter element
based upon differential pressure
with little or no regard to the
delivered air quality. Due to the
high initial differential pressure,
recommended element changes
are between 500 mbar (7 psi) and
700 mbar (10 psi) differential. This
high change point will cost you a
massive 5% extra in compressor
energy.
When purchasing compressed air purification
equipment, the delivered air quality and lifetime
costs must always be considered.
All domnick hunter products are designed
to provide a cost effective solution to
compressed air contamination, with
delivered air quality to the latest
international standards and with the lowest
of operational costs.
OIL-X EVOLUTION compressed air filters use
very little energy as they have a low
resistance to air flow. Advancements such
as deep bed pleating, graded density media
and an oleophobic coating have led to a high
performance filter element with low initial
energy costs.
Differential pressure starts low and stays
low throughout it's life. Service life is no
longer dependent upon differential pressure,
but on annual filter element change backed
up with a one year air quality guarantee.

The most energy efficient
filter element in the world
Full Flow Inlet
Inlet conduit matches inlet
diameter, reducing pressure
drop and running costs.
The new domnick hunter
OIL-X EVOLUTION range of
compressed air filters has been
designed from the outset to meet
current and forthcoming
requirements for compressed
air quality. Using aerospace
technology, domnick hunter has
optimised the flow path through
the housing and element,
significantly reducing air turbulence
and pressure losses. Providing an
optimal flow path is key to reducing
system operating costs.
Even Flow Distribution
Air flow is distributed evenly
throughout the filter element
using a flow distributor.
Deep Bed Pleating
For particle and aerosol removal,
deep bed pleating provides 4.5 x more
filter media than an ordinary element,
giving a larger filtration area, lower
flow velocitites, increased dirt holding
capacity, lower running costs and a
more compact filter element.
Oil Vapour Removal
Graded density
nanofibre filter media
Graded density further
improves filter life and
overall performance by
trapping larger particles
in the pre-filtration layer
of the filter media.
Whilst mechanical
filtration is capable
of removing extremely
fine liquids and solid
Activated carbon
particles, it cannot
remove gaseous contaminants such as oil
vapour or odours. To efficiently remove
these vapours, OIL-X EVOLUTION
ACS/OVR filters employ adsorption
techniques using a deep bed of activated
carbon.
Conical Air Diffuser
Air flow distribution
is further improved by
elimination of turbulence.
4
Aerospace Turning Vanes
Turning vanes effectively direct
air flow into the filter element.
Air Stabilisers
Smooth outlet air flow.
High Efficiency Drainage Layer
Ensures coalesced liquids are
removed quickly and efficiently.
Special
Filter Media
Oleophobic
nanofibre filter
media actively
repels oil and
water to reduce
pressure drop and
keep running costs
to a minimum.
Drainage Ribs
Filter housing and element integrate
to provide capillary action which greatly
improves liquid drainage. Interaction
between housing and element also
ensures maximum coalescing
performance is achieved at all times.
Filter media actively
repels oil and water
No Wet Band Formation
Allows more air flow through
a smaller filter element.

Annual filter element changes are essential
Service contracts
To maintain your guaranteed air quality, filter
elements must be replaced every year with genuine
domnick hunter parts.
For peace of mind, domnick hunter can manage your
compressed air quality and guarantee future performance
with a world-wide service contract. Further details can
be found on www.domnickhunter.com
Throughout it's life, the filter element is constantly under
bombardment from oily, acidic condensate and high
velocity dirt particles, which it has to remove and retain
to protect your compressed air system. Over time, this
can weaken the filter media and reduce filtration
performance. This potential but critical reduction in
filtration performance cannot be detected by simple
differential pressure monitoring techniques.
Annual filter element changes are therefore essential,
and failure to replace every year could result in reduced
production performance, degrading air quality and
increased operational costs.
Annual filter element changes ensure :
• Optimal performance is maintained
• Air quality continues to meet
international standards
• Performance guarantee is extended
for a further 12 months
• Low operational costs
• Continued protection of downstream
equipment & processes
Helping you manage your
maintenance programs
domnick hunter can help you manage
your filter or other compressed air
treatment equipment maintenance
programs by reminding you when
maintenance is due, parts
required and equipment location.

High quality compressed air
from generation to application
Compressed Air Quality
& Product Selection
High quality compressed air
from generation to application
The quality of air required throughout
a typical compressed air system can vary.
The extensive range of purification
equipment available from domnick hunter
is ideal for both centralised and
decentralised compressed air systems.
This allows the user to specify the quality
of air for each particular application, from
general purpose ring main protection,
through to critical clean dry air (CDA) point
of use systems.
COMPRESSED AIR QUALITY TO ISO 8573.1:2001
The international standard for compressed air quality provides a
simple system of classification for the three main contaminants
present in any compressed air system - DIRT, WATER and OIL. To
specify the quality class required for a particular application, simply
list the class for each contaminant in turn. For further information
on how to achieve ISO 8573.1:2001 air quality standards, refer to
publication reference 17 400 4765.
0.1-0.5micron
domnick hunter can tailor its range of
purification equipment to exactly match
system requirements, ensuring both capital
and operational costs are kept to a
minimum.
To achieve the levels of cleanliness specified
by ISO 8573.1 2001 a careful approach to
system design, commissioning and
operation must be employed.

Solid Particulate
It is highly recommended that the
compressed air is treated prior to entry into
the distribution system as well as at each
usage point or application.
CLASS
This approach to system design provides
the most cost effective solution to system
purification as it not only removes the
contamination already in the distribution
system, it ensures that only the most critical
area’s receive air treated to the highest level.
Class 3 AO (AR for dry particulate)
The example system layout drawing

In many instances the compressed air
system will be supplying air to more than
one application and although the purification
equipment specified in the compressor
room would remain unchanged, the point of
use protection will vary depending upon the
air quality requirements of each application.
Class 5 CRD Refrigeration Dryer Sized for +3°C PDP
For example, air used for the pneumatic
conveying of food stuffs or ingredients will
require the highest level of purification,
whilst the air used to operate the
pneumatics on the production machinery
may only require general purpose
protection.
