COMPRESSED AIR - THE 4TH UTILITY
COMPRESSED AIR IS A SAFE AND RELIABLE POWER SOURCE THAT IS WIDELY USED THROUGHOUT INDUSTRY.
APPROXIMATELY 90% OF ALL COMPANIES USE COMPRESSED AIR IN SOME ASPECT OF THEIR OPERATIONS,
HOWEVER UNLIKE GAS, WATER AND ELECTRICITY, COMPRESSED AIR IS GENERATED ON-SITE, GIVING THE USER
RESPONSIBILITY FOR AIR QUALITY AND OPERATIONAL COSTS.
COMPRESSED AIR IS NOT WITHOUT IT’S PROBLEMS, WITH ALL SYSTEMS SUFFERING FROM PERFORMANCE
AND RELIABILITY ISSUES. ALMOST ALL OF THESE CAN BE DIRECTLY ATTRIBUTED TO CONTAMINATION, THE
MAIN SOURCES OF WHICH ARE :
There are 10 major contaminants found in a compressed air system, these are:
Contaminant removal
Failure to remove this contamination can cause numerous
problems in the compressed air system, such as:
•Corrosion within storage vessels and the
distribution system
• Blocked or frozen valves, cylinders, air motors
and tools
• Damaged production equipment
• Premature unplanned desiccant changes
for adsorption dryers
In addition to problems associated with the compressed
air system itself, allowing contamination such as water,
particulate, oil and micro-organisms to exhaust from valves,
cylinders, air motors and tools, can lead to an unhealthy
working environment with the potential for personal injury,
staff absences and financial compensation claims.
Compressed air contamination will ultimately lead to:
•Inefficient production processes
• Spoiled, damaged or reworked products
• Reduced production efficiency
• Increase manufacturing costs

CONTAMINANTS
1
The largest quantity of contamination introduced into the
compressed air system originates from the atmospheric air
drawn into the compressor and not as often believed,
introduced by the compressor itself. The most prolific and
problematic of the contaminants is water which accounts
for 99.9% of the total liquid contamination found in a
compressed air system.
High efficiency compressed air filtration is not only used
to remove particulate and oil, but more importantly it
removes water aerosols and is key to operating an efficient
and cost effective compressed air system.
Regardless of what type of compressor is installed,
the same level of filtration is required.
The table belowhighlights each of the purification technologies required to remove the different contaminants present
in the compressed air system.

WHICH 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. WHEN
PURCHASING PURIFICATION EQUIPMENT, THE DELIVERED AIR QUALITY, COST OF OPERATION AND THE
OVERALL COST OF OWNERSHIP MUST ALWAYS BE CONSIDERED.

Correct selection of filtration media
Coalescing and dust removal filters use a high
efficiency borosilicate glass nanofibre material
which has a 96% voids volume, providing
media with excellent filtration efficiency and
ahigh dirt holding capacity.
AIR QUALITY - GUARANTEED
Filtration performance of OIL-X EVOLUTION filters arenot only tried and tested by domnick hunter, but has also been independently validated by Lloyds Register.
AIR QUALITY
THE DOMNICK HUNTER OIL-X EVOLUTION RANGE OF COMPRESSED AIR FILTERS HAS BEEN DESIGNED FROM THE
OUTSET TO MEET THE REQUIREMENTS OF ISO 8573.1 : 2001, THE INTERNATIONAL STANDARD FOR COMPRESSED
AIR QUALITY, WHEN VALIDATED IN ACCORDANCE WITH THE REQUIREMENTS OF ISO 12500, THE INTERNATIONAL
STANDARD FOR FILTER TESTING AND THE TEST METHODS OF ISO 8573.2, ISO 8573.4 AND ISO 8573.5.
OIL-X EVOLUTION coalescing filters utilise four drainage methods
to ensure high performance, whilst conventional filters only use one.
Drainage method 1 High efficiency drainage layer provides
increased liquid drainage, improved
chemical compatibility and higher
operational temperatures when compared
to conventional materials.
Drainage method 2
Surface tension breakers are moulded into
the lower filter element endcap to prevent
liquid from sticking, and to ensure fast and
efficient drainage of coalesced liquid.
Drainage method 3
Drainage ribs castinto the filter bowl
compress the lower part of the filter
element, allowing bulk liquid to rapidly drain
from the filter element through capillary
action.
Drainage method 4
Traditional elements have a build up of liquid
known as a “wet band” where the drainage
layer is glued into the lower endcap.
The OIL-X EVOLUTION design wraps the
drainage layer under lower endcap removing
coalesced liquid from the air flow path,
increasing liquid removal efficiency, and
providing more usable filtration surface area.
Construction of the filtration media
into a filter element
OIL-X EVOLUTION filter elements use
pleated not wrapped filter media, which
is constructed using a unique deep bed
pleating technique. This provides 450% more
filtration surfacearea when compared to
atraditional wrapped filter element and
around 200% more surface area compared
to a traditional pleated element.
Deep bed pleating also reduces the air flow
velocity within the media, which further
improves filtration performance.
Additionally, the high efficiency AA and AAR
grade elements have a unique graded
density media construction which provides
even greater filtration performance without
adding to pressure loss or energy
consumption.

ENERGY EFFICIENCY
ANY RESTRICTION TO AIRFLOW WITHIN A FILTER HOUSING / ELEMENT WILL REDUCE THE SYSTEM
PRESSURE. TO GENERATE COMPRESSED AIR, LARGE AMOUNTS OF ELECTRICAL ENERGY IS REQUIRED,
THEREFORE ANY PRESSURE LOST WITHIN THE SYSTEM CAN BE DIRECTLY CONVERTED INTO A COST FOR
WASTED ENERGY. THE HIGHER THE PRESSURE LOSS, THE HIGHER THE ENERGY COSTS.
Pressure loss in a compressed air filter is a combination of fixed pressure losses and incremental pressure losses. Fixed pressure
losses come from the filter housing and the interface between the filter housing and filter element. Incremental pressure losses
come from the filter element as it blocks up with contamination during operation.
Inmost filters, high operational costs are generally due to a poorly designed airflow path within the filter housing and element and
poorly selected filtration media. In addition to this, the high differential pressure change points recommended by many filter
manufacturers increase operational costs even further.
Providing an optimal flow
path for the compressed air
is key to reducing system
operating costs.
“Bell mouth” housing inlet
&full flow inlet conduit
OIL-X EVOLUTION filter housings feature
a"Bell Mouth" inlet to provide a smooth, turbulent
free transition for the air as it enters into the filter
element without restriction through the full flow
element inlet conduit.
Smooth 90° elbow &
aerospaceturning vanes
Flow distributor Filter models 015 to055 include an upper flow
distributor and all models include a lower conical
flow diffuser.
The upper flow distributor provides turbulent free
distribution of the air flow throughout the filter
element ensuring full utilisation of all available
filtration media, increasing filtration performance
and reducing energy consumption.
The combination of conical flow diffuser and a
drainage layer wrapped under the lower endcap
allows airflow through the lowest section of the
element, which is not possible on conventional filters
due to the position of the "wet band".
Specialistmedia
treatment
OIL-X EVOLUTION uses a specialist
treatment for it’s filter media which
actively repels oil and water,
preventing the fibres of the media
from soaking up liquid. This ensures
coalesced liquids do not reduce the
high voids volume of the filter media,
therefore reducing system pressure
losses and energy consumption.
AEROSPACE FLOW MANAGEMENT SYSTEM
Deep bed
pleating
Deep bed pleating of the filter
media reduces the air flow velocity
within the media, which in addition
toimproving the filtration
performance of the element,
significantly reduces pressure
losses and energy consumption.
In aerodynamic terms, a design which turns the air sharply
through 90°is known as an inefficient corner. This typically
has always been the method used to direct air into a
compressed air filter element.
OIL-X EVOLUTION uses a smooth 90° elbow to direct air
intothe filter element, reducing turbulenceand pressure
losses significantly by turning the inefficient, sharp 90°
corner into an efficient one.
As the diameter for the conduit increases, the benefits are
reduced, therefore filter models 025 to 055 also include
aerospaceturning vanes which channels the air through a
number of smaller, more efficient corners, reducing
pressure loss and energy consumption even further.
